Flint chemical formula
Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion (≈3 × 10 −6 K −1 at 20 °C), making them more resistant to thermal shock than any other common glass. Such glass is subjected to less thermal ...Flint, chert, and jasper are names commonly used by geologists and by the general public for opaque specimens of microcrystalline quartz. The same hand specimen might be called "chert" by one person, "flint" by another, and "jasper" by a third. The name used can be influenced by the educational background of the person, the physical properties ...
