Wollastonite

Wollastonite

Wollastonite is a calcium inosilicate mineral with the chemical formula CaSiO₃. It is typically found in metamorphosed limestone and is known for its needle-like crystal structure. Wollastonite is used in various industrial applications, particularly in ceramics, paints, and the production of specialty materials.

Wollastonite is commonly used in the ceramics industry to improve the strength, durability, and thermal stability of ceramic materials. It is added to porcelain, tiles, and other ceramic bodies to enhance their properties.

It helps to reduce the firing temperature and improves the glaze quality, resulting in smoother and more durable ceramic products.
