Calcium hexafluorosilicate(CAS: 16925-39-6)

Calcium hexafluorosilicate (CAS: 16925-39-6) is a solid, white crystalline compound with a high molecular weight. It is insoluble in water but soluble in acid. This compound is highly reactive, particularly with moisture, leading to the release of hydrogen fluoride gas.

Calcium hexafluorosilicate is typically synthesized by reacting calcium fluoride with silicon tetrafluoride. The process requires careful temperature control and is often carried out under anhydrous conditions to prevent hydrolysis and the formation of hydrogen fluoride gas.

Calcium hexafluorosilicate (CAS: 16925-39-6) is used in the pharmaceutical industry for capsule production and as a pH regulator. It is also utilized in the polymer industry for stabilizing plastic and rubber compounds. Additionally, it finds application in the semiconductor industry as a dopant.

When handling Calcium hexafluorosilicate (CAS: 16925-39-6), it is essential to use personal protective equipment (PPE) such as gloves and safety glasses. Work should be conducted in a well-ventilated area or a fume hood. Spills should be cleaned up using appropriate absorbents, and the area should be washed down with water. Always refer to the Safety Data Sheet (SDS) for detailed instructions.
