What are the differences in production processes and applications between calcined talc and uncalcined talc?

Liaoning Haicheng's talc powder, the difference between calcined and uncalcined talc lies in: talc is a non-metallic mineral product, primarily composed of silicon dioxide, magnesium oxide, calcium carbonate, etc. It boasts good acid resistance, strong corrosion resistance, high melting point, high whiteness content, high anti-adhesion properties, and excellent low thermal conductivity. It is suitable for uses in coatings, paints, plastics, rubbers, and more.

The primary difference between calcined talc and uncalcined talc lies in their whiteness, composition, and viscosity. Calcined talc has a significantly reduced amount of calcium carbonate. The product is processed through a series of processes, including mining, crushing, and acid washing, among others.

Burnt talc with improved brightness components enhances its physical and chemical properties, improving its resistance to high temperatures, thereby broadening the application scope of talc powder.
