Industrial Uses of Pyrophyllite

White Cement

Fiberglass

Refractories

Plastics

Porcelain Tiles

Agriculture

Paint Industry

Other Uses

White Cement

Pyrophyllite is used as an alternative to Kaolin in the white cement production to reduce the temperature of making clinker due to increased interaction in Pyrophyllite. The clinker formulations based on Pyrophyllite generally have better physical properties compared to the clinker made with Kaolin and Silica. It also maintains +90% whiteness in the final product of white cement.

Fiberglass

Pyrophyllite ore contains a high percentage of aluminum oxide and a low concentration of iron, titanium oxides, and alkalis, thus it can be effectively used in the manufacture of fiberglass as a partial substitute for kaolin. it has a wide range of advantages such as reducing the cost of production and reducing the amount of sand added to the main mixtures, which helps speed up the disslution by 30% and increase productivity by 12%. it also saves the energy used in smelting by 20% to 25%.

Refractories

Known for its high melting point and thermal stability, Pyrophyllite is an essential raw material in manufacturing of refractory materials which are used in lining melting furnaces and crafting molds resistant to extreme temperatures.

Plastics

Pyrophyllite acts as a reinforcing filler in the plastics industry, improving their mechanical strength, dimensional stability, and resistance to heat and chemicals. It finds application in the production of plastic pipes, films, coatings, composites, and various molded plastic products.

Porcelain Tiles

Pyrophyllite is used in the ceramics industry to enhance mechanical characteristics, chemical resistance, and thermal shock resistance. This mineral also offers excellent dielectric strength and promotes the glazing of finished products without cracks. Utilizing Pyrophyllite in the ceramic industry allows for faster firing cycles than comparable materials due to its quick heating and ability to transform into mullite at a lower temperature (1100°C).

Agriculture

Pyrophyllite serves as a valuable fertilizer carrier, enriched with essential nutrients like calcium, magnesium, potassium, and iron. Its unique structure aids in nutrient retention, soil improvement, and reduction of leaching, contributing to sustainable agricultural practices. As well as the ability to absorb harmful heavy metals from the soil.

Paint Industry

Pyrophyllite is chosen for paint production based on its characteristics such as whiteness, particle size, oil absorption capacity, and acid solubility, which contribute to its smooth application due to its layered molecular structure. It serves as a pigment extender and suspending agent, improving paint volume, and preventing cracking.

Other Uses

In addition to those main industries, Pyrophyllite can be used in the industry of paper, insecticides, electrical insulation, rubber, personal care, pharmaceuticals and glass.
