硅灰石的主要成分是偏硅酸钙（CaSiO₃），其化学式为Ca₃Si₃O₉，其中氧化钙（CaO）占43%左右，二氧化硅（SiO₂）占52%左右。
The main component of wollastonite is calcium metasilicate (CaSiO), and its chemical formula is CaSiO, of which calcium oxide (CaO) accounts for about 43% and silica (SiO) accounts for about 52%.
Chemical composition of wollastonite
The chemical composition of wollastonite mainly includes calcium oxide (CaO) and silicon dioxide (SiO 2), of which CaO accounts for about 43% and SiO 2 accounts for about 52%. In addition, wollastonite often contains small amounts of iron, magnesium, manganese and other elements.
Physical properties of wollastonite
Wollastonite is a non-toxic, tasteless, high temperature resistant mineral material with a small coefficient of thermal expansion, good electrical insulation and chemical stability, and a certain resistance to acid and alkali. Its heat resistance is good and can remain stable at high temperatures. In addition, wollastonite also has excellent processing stability and production molding performance, which can reduce processing viscosity and improve the stability of production process.
The use of wollastonite
Wollastonite is widely used in a variety of industries, including:
1. Metallurgy: as a flux, to reduce the melting point.
2. Ceramics: used as raw materials to enhance the strength and heat resistance of products.
3. Papermaking: used as fillers and reinforcements.
4. Friction materials: improve melting speed and high temperature shock resistance
5. Glass fiber: reduce the furnace melting temperature and increase the hardening speed of fiber forming
6. Welding material: used for electrode coating, which can accelerate the melting speed
7. Coatings and paints: improve the leveling and wear resistance of the coating.
8. Rubber and plastics: used as fillers to enhance the mechanical and electrical properties of materials.
9. Building materials: used to make insulation materials and gas filtration materials.
