Another name: Water glass
CAS No.: 1344-09-8
HS Code: 28391910
There are two different forms, including:
Solid sodium silicate
Lump shape
Size: 4-5CM
Light green to light blue crystal, transparent or semi-transparent.
Liquid sodium silicate
Liquid state
Colorless clear or light gray deup
Different density ° Baumé Is available
The liquid is common, colorless clear or light gray deup. The solid is light blue or light green crystals, transparent or semi-transparent.
Sodium Silicate is made from sodium oxide and silicon dioxide, the molar ratio between them called modulus, the physical property and usage would be different if the modulus changes
Use:
Sodium Silicate is the indispensable raw material of washing powder, detergent and soap. Settling agent and water softener for water treatment; It is the fundamental material of the chemical products such as silica gel, white carbon black, zeolite molecular sieve. It can also be used in the industry of binder, foundry, mineral floating select., acid-resisting material, constructional material
