CAS 16961-80-1: CALCIUM HEXAFLUOROSILICATE DIHYDRATE

Calcium hexafluoro-silicate (CaSiF6) is a compound that contains silicon and calcium. It has an anhydrous crystal structure and can be prepared by the reaction of silicon tetrachloride and calcium chloride. The thermal expansion of CaSiF6 is 10.5 x 10-6/°C, which is much lower than that of SiO2. This material can be used for high-frequency devices due to its low dielectric constant, wide band gap, and high dielectric strength. CaSiF6 has been shown to be a good candidate for use in the manufacture of solar cells because it is inexpensive, non-toxic, and able to withstand high temperatures.
