1.
Talc
The
composition of talc contains the aqueous silicon acid magnesium. Molecular
formula is Mg3SI4O10(OH)2,It
belongs to single inclined crystal which colour is white, light green, light
yellow or pink. Degree of hardness of talc is 1 and the specific weight is
2.7-2.8.
2.
Characteristic
The talc
has a character of lubricate、fire-proof、anti- acidity、insulate、higher melt
degree、the non-alacrity chemistry、soft、good lustre、strong adsorptive.
