Cristobalite
Cristobalite is a mineral composed of silicon dioxide (SiO2) and belongs to the tetragonal crystal system. It is classified in the tectosilicate group and is identified by the Strunz classification 4.DA.15 and the Dana classification 75.1.1.1. Cristobalite typically exhibits a white streak and has a vitreous luster. Its physical properties include a hardness of approximately 6.5 to 7 on the Mohs scale and a relatively low density. The mineral is notable for its unique crystal structure, which is described by the space group P4₁2₁2. It is commonly colorless but may appear in various hues due to impurities.
