CAS 14464-46-1
:Cristobalite, (SiO2)
Description:
Cristobalite is a high-temperature polymorph of silica (SiO2) characterized by its tetragonal crystal structure. It typically forms at temperatures above 1470 °C and is stable at elevated temperatures, making it significant in various geological and industrial processes. Cristobalite is less stable than quartz at room temperature but can transform back into quartz upon cooling. It is known for its low thermal expansion coefficient, which contributes to its utility in high-temperature applications, such as ceramics and glass manufacturing. The substance is generally colorless or white, though impurities can impart different hues. Cristobalite exhibits high hardness and chemical resistance, making it suitable for use in abrasive materials and as a filler in various products. However, inhalation of cristobalite dust can pose health risks, including silicosis, a lung disease caused by silica exposure. Therefore, handling cristobalite requires appropriate safety measures to minimize dust generation and exposure. Its CAS number, 14464-46-1, is used for regulatory and identification purposes in chemical databases.
