Silicosis Wikipedia

Amorphous silica consists of kieselgur from the skeletons of diatoms and vitreous silica produced by heating and then rapid cooling of crystalline silica Amorphous silica is less toxic than crystalline but not biologically inert and diatomite when heated can convert to tridymite or cristobalite Silica flour is nearly pure SiO 2 finely ground Silica flour has been used as a polisher
