The other carbonate mineral in common use as a filler is dolomite calcium magnesium carbonate (CaC03. MgC03). It is in the trigonal crystal system and is usually found as rhombohedral crystals with curved composite faces. Dolomite is harder (3.5), denser (2.85), and slightly more acid resistant than calcite, bnt in general, the mineral properties and properties in a polymer are similar. [Pg.61]
