Products Description
SIL-CO-SIL® Ground Silica products are produced from high purity silica, precision ground from 125 to 45 micron topsize. Our ground silicas are inherently inert, bright white, with low moisture and are at least 99.5% Si02.
FLINT - (SiO2) (m.p. 3119o F/1715o C) is the dark porous variety of chert that contains organic matter (chert is a hard, extremely dense, dull to semi-glossy sedimentary rock which is microcrystalline to cryptocrystalline quartz). True flint is very fine (cryptocrystalline) hydrated silica (1% molecular bound water) and is less dense than Quartz Sand due to a fine porous structure. The name flint is a carry over from England and France in which the true flints were prepared by calcination and grinding. Many geologists and archeologists suggest that the term flint be discarded or used only to identify artifacts of prehistoric humans (see also Silica).
