Appearance
and character:
Monoclinic
system, short crystal columnar, aggregate is dense and massive or husk like,
colorless, transparent, sometimes with light yellow or green, soluble in
water. White, odorless, bitter crystal or powder with hygroscopicity. The
shape is colorless, transparent, large crystalline or granular small crystal.
Sodium sulfate is a strong acid and strong alkali salt of oxygen containing
acid.
Uses:
1.
The chemical industry is used to make sodium sulfide sodium silicate and
other chemical products.
2.
The cooking agent used in the manufacture of sulphate pulp.
3.
