About synthetic zeolites

Synthetic zeolites are manufactured aluminosilicate minerals with a sponge-like structure, made up of tiny pores (frameworks) that make them useful as catalysts or ultrafine filters. They are commonly known as molecular sieves and can be designed to selectively adsorb molecules or ions dependant on their unique construction and have the ability to be regenerated over and over again for re-use (recycled).

Zeolites act much like a magnet that can hold cations, like heavy metal, ammonia, low level radioactive elements, toxins, petrochemicals, many different type of gases and a multitude of various solutions.

The selectivity properties of different synthetic zeolites enable them to be effective in wastewater treatment applications, water filters and as ion exchangers in many everyday dishwashing and laundry detergents.

Zeolites play an important role in a cleaner and safer environment.

  • zeolites are an effective substitute for harmful phosphates in powder detergent, now banned in many parts of the world because of blue green algae toxicity in waterways
  • as catalysts zeolites increase process efficiencies = decrease in energy consumption
  • zeolites can act as solid acids and reduced the need for more corrosive liquid acids
  • zeolites adsorbent capabilities see them widely used in water treatment i.e. heavy metal removal including those produced by nuclear fission
  • as redox catalysts sorbents zeolites can help remove exhaust gases and CFC’s

Our proprietary mineral processing technology also presents as a potential commercial remediation solution for suitable mine tailings/residues, by applying tail streams as feed for low cost production of high value zeolites.

Synthetic zeolites can be manufactured for specific applications in a range of industrial environments, the primary types are:

Zeolite A

Zeolite A is a sodium aluminosilicate and is utilized as a builder in tablets and detergent powders for the water softening in washing process. This type of zeolite is also known as Linde Type A (LTA), which belongs to the aluminosilicate molecular sieves family. Sodium ions present in zeolite A can be replaced with other cations, including potassium, lithium, and calcium. There are around 150 synthetic zeolites designed for the specific purposes. However, the most common type is zeolite type A, which include:

  • 4A a detergent builder and polyvinyl chloride (PVC) heat  stabiliser. Type 4A represents over 50% of total global volume of  synthetic zeolites used today.
  • 3A a molecular is a molecular sieve that has a pore size that is 3 angstrom (3A), hence it will not adsorb any molecules larger than 3A. It is a very effective and reliable desiccant (drying agent) and is used in a wide variety of commercial applications, some of which include, natural gas drying, refrigerant drying, moisture removal in polyurethane plastic/paint, static drying of insulating glass units and is also applied in method of drying that is used by fuel ethanol producers.
  • 5A a molecular sieve that has a pore size that is 5 angstrom (5A). It cannot adsorb any molecules smaller than 5A and primary applications are separation of alkane types, co-adsorption of carbon dioxide and moisture, along with pressure swing adsorption (PSA) for gases.

Zeolite X

Zeolite X belongs to Faujasite family which are used as catalysts and sorbents. There are several different types of zeolite X dependent on pore size. It is mainly used in the gas drying applications, however, it has a variety of industrial applications, including gas separation and adsorption, besides being utilized as a catalyst. Zeolite X ion exchange properties also make it effective in removing toxins from wastewater. One key type of zeolite X is:

  • 13X  has larger pore size than Type A zeolites (circa 10 angstroms) and is primarily used in types of air refining (ie removing carbon dioxide and water), removal of grease and solvents and in gas pressure swing adsorption.

Zeolite ZSM-5

Zeolite Zsm-5 belongs to pentasil family of zeolites . This type of zeolite is extensively utilized in the petroleum sector as a heterogeneous catalyst. It is comprised of numerous pentasil units combined together to form pentasil chains by oxygen bridges. These pentasil chains form corrugated sheets with interconnected oxygen bridges. ZSM-5 main applications are in fine chemical production processes.

Zeolite Y

Zeolite Y is utilized as a fluid cracking catalyst of heavy petroleum distillates to increase the yield of diesel and gasoline fuel from crude oil. Zeolite Y is among the most popular catalysts due to its properties, such as good hydrothermal stability and inherent surface acidity. The hydrothermal and thermal stability of the zeolite Y is associated with its silica and alumina ratio that plays crucial role in materials produced for applications, such as  catalytic cracking catalysts in the oil industry.

Primary applications:

  • Detergent builder
  • PVC heat  stabiliser
  • Moisture removal / drying across a range of substances
  • Separation and purification ie Water treatments and air purification
  • Cracking processes ie Oil and Gas industry


Synthetic zeolites play an important role as ion exchangers in many everyday dishwashing and laundry detergents, assisting to remove calcium and magnesium and soften water so they work more effectively. Synthetic zeolites are sought after as a detergent builder as they present an environmentally friendly substitute for toxic phosphates (which are banned in the USA, Europe, Australia and some parts of Asia).

Water treatment

The rise in adoption of synthetic zeolite based adsorbents in major end use industries including water treatment, chemicals and petrochemicals particularly in the Asia Pacific, Middle East and Latin America has boosted the growth of the market and this is expected to continue over the next decade.

Rising environmental concerns regarding wastewater health hazards have triggered regulatory bodies across the globe to mandate the use of synthetic zeolite based adsorbents. The stringent regulatory norms specifically in the U.S. and Europe to disinfect both water and air have also been boosting the demand for adsorbents [1]

Other applications

Synthetic zeolite is also used as a catalyst in the pharmaceutical and petroleum industries, in catalytic crackers to break large hydrocarbon molecules into gasoline, diesel, kerosene and waxes.

Zeolites are used in agriculture to improve soil conditions, control release of fertilizers and increase water use efficiency, in turn improving yield. They also have potential applications as inputs in animal feed supplements, as mycotoxin adsorbents.

High Purity Alumina (HPA)

The HPA market is experiencing significant growth. Demand is primarily being driven by sapphire glass and lithium-ion batteries. HPA is a very pure form of aluminium oxide (Al2O3) and a pre-cursor material required for the manufacturing of sapphire glass and ceramic coated Lithium-Ion-Battery separators.

Synthetic Sapphire

HPA is a critical input in the production of synthetic sapphire – one which has no substitute. Applications:

  • Substrates for LED lights, Lenses and Semiconductors
  • Scratch-resistant sapphire glass used for optical lenses, watch faces, televisions, tablet and smartphone components
  • Bio-medical devices and Phosphors

The higher brightness, energy efficiency, and longer life span of LED lights are some of the major factors that offer tremendous opportunities for LED lighting market in years to come.

Lithium-ion Batteries

HPA’s fastest growing market is in Lithium-ion batteries.

HPA is now being used as a coating on the separators in Lithium-ion batteries in the EV industry.

The separator is vital to the safety, integrity and performance of the Lithium-ion battery in vehicles where the battery is subjected to peculiar stresses. In the past most Lithium-ion battery separators were based on polyethylene or polypropylene which were adequate for cathodes such as lithium iron phosphate, lithium manganese oxide and lithium cobalt oxides. This has been fine up until recently when demand for higher energy density in a smaller more compact battery has meant higher operating temperatures in the batteries.

This is where the use of HPA coated separators becomes extremely important in reducing flammability as the separators can tolerate much higher temperatures than traditional separators (>200oC), resulting in thermal stability.

HPA coated separators have also been shown to significantly lengthen battery life due to lower self-discharge and increased battery discharge rate.

CRU demand forecast for 4N HPA in lithium-ion batteries is set to increase at an extraordinary CAGR of 57.5% between 2017 and 2025.
