Cristobalite, Powder, 99.95%, -4 mesh approx

Cristobalite is used in the production of high-temperature refractory materials and investment casting molds due to its high melting point and volume stability at elevated temperatures.

Used as a precursor or source material for depositing silicon dioxide thin films which serve as low-refractive index layers in multilayer optical coatings.

High-purity cristobalite-derived silica is utilized in the fabrication of sputtering targets for the deposition of dielectric insulating layers in microelectronic and optical applications.

Cristobalite serves as a high-purity source material for physical vapor deposition processes to create protective and functional silica coatings.
