or Mineral Information Institute, silica is the chemical name of quartz, which can also be known as silicon dioxide. In pharmaceuticals it is used as a filler, or in food production as an anti-coagulant. It is also used in the manufacturing...
silicon (ˈsɪlɪkən) n (Elements & Compounds) a.a brittle metalloid element that exists in two allotropic forms; occurs principally in sand, quartz, granite, feldspar, and clay. It is usually a grey crystalline solid but is also found as a brown amorphous powder. It is used in...
Is dolomite a carbonate mineral? Carbonate minerals: Some of the more common types of carbonate minerals consist of carbonate ions complexed with calcium, magnesium, iron, and manganese. However, carbonate ions can also complex with rare-earth metals, although the occurrence of this is less common...
