Cristobalite Silica

Cristobalite Silica: Properties and Applications

Cristobalite silica is one of the three types of silica minerals found in the Earth’s crust. This mineral naturally occurs as transparent or white crystals and is chemically represented by the formula SiO₂.

Properties of Cristobalite Silica:

• High Thermal Resistance: Cristobalite is the high-temperature phase of silica, forming at temperatures above 1450°C.

• High Purity and Whiteness: This material is produced with a purity exceeding 95% and whiteness over 98%, making it a potential substitute for titanium oxide in certain applications.

Applications of Cristobalite Silica:

1. Paint Industry:

   • Used as a high-whiteness filler in the production of paints and coatings.

2. Building Materials:

   • Applied in the manufacture of construction materials resistant to heat and pressure.

3. Military and Petrochemical Industries:

   • Utilized due to its high resistance to acids, bases, and chemicals.

4. Casting Plasters Production:

   • Serves as a primary material in producing high-quality casting plasters.
