Multi - application and industrial value of wollastonite

Wollastonite is a natural calcium silicate mineral. With its unique needle-like or fibrous structure, high whiteness, chemical corrosion resistance and low water absorption, it has become an indispensable functional material in modern industry and is widely used in ceramics, plastics, coatings, metallurgy and other fields.

In the ceramic industry, wollastonite is a high-quality flux and strengthening agent. It can significantly reduce the firing temperature of ceramics, shorten the firing cycle, and reduce the shrinkage and cracking risk of products. Ceramic products added with wollastonite have higher mechanical strength and better heat resistance, and are widely used in the production of building tiles, sanitary ware and high-end daily-use ceramics.

As a filler modifier for plastics and rubber, the needle-like structure of wollastonite can effectively improve the mechanical properties of materials. After surface treatment, it can enhance the impact resistance, tensile strength and dimensional stability of polymer and reduce the production cost. In the fields of automobile parts, electronic equipment housings and so on, wollastonite filled plastics are gradually replacing traditional metal parts, realizing the double promotion of lightweight and durability.

In addition, wollastonite can replace part of titanium dioxide in the coating, improving the weather resistance and corrosion resistance of the coating; Used as the base material of continuous casting flux in metallurgical industry to improve the quality of molten steel; Its adsorption characteristics are also used in wastewater treatment and development of environmental protection materials. With the development of technology, the application potential of wollastonite in emerging fields such as high-performance composite materials and biomedicine has been continuously tapped, showing a broad market prospect.
