Sodium metasilicate nonahydrate is white crystal or powder, mainly used in detergent industry.

Sodium Metasilicate Nonahydrate Na2SiO3 9H2O

Chemical Formular: Na2SiO3 9H2O

CAS NO.: 13517-24-3

 

Property:

Sodium metasilicate nonahydrate is strongly alkaline, having strong capacity of cleaning, buffering and softening, 

counteracting acidic contamination, emulsifying fat and oil, deflocculating to inorganic. 

 

Application:

Sodium Metasilicate can replace STPP to be used for the manufacture of effective detergents and rust remover for metal, 

reducing environmental pollution, preventing corrosion for metal (zinc, aluminum, etc.). 

Therefore, sodium metasilicate anhydrous is widely used for the manufacture of a variety of detergents, 

used as rust remover for metal, grinding aids for ceramics, deinking agent for paper, dyeing and printing auxiliary 

for removing oil in textile industry, and also used as the raw material for flameproofing agent, plastic maintenance 

agent, water retention agent, etc.
