A large number of silicate minerals exist in nature. Some of the important minerals are : feldspar i.e. Albite NaAlSi3O8, zeolites e.g. chabazite Ca2[(AlO2)4 (SiO2)8.H2O, micas [KAl2(Si3AlO10(OH)2] and asbestos [Mg3(Si2O5)(OH)4]. The basic structural unit in silicate is the SiO44- terahedra. The two important man-made silicates are glass and cement. Silicates are … [Read more...] about Silicates
