Potassium Silicofluoride K2SiF6

1.Properties of potassium silicofluoride K2SiF6: 

It is white crystals or powder, odorless, tasteless and weak acidic and have toxic. The density of hexagonal crystal is 3.*8.It is hygroscopic.It is slightly soluble in water, soluble in hydrochloric acid. Its solubility is slightly higher as the temperature gets higher. It is decomposed by heat to form potassium fluoride(KF) and silicon tetrafluoride(SiF4). It is hydrolyzed in hot water to form potassium fluoride(KF),hydrogen fluoride(HF) and silicate acid(H2SiO3).

2.Usage of potassium silicofluoride K2SiF6: 

For wood preservation, fabrication of ceramics and all kinds of optical glass, smelting of lead and magnesium, or used as raw material for synthesis of mica and preserving material.

3.Packing: Plastic lined woven bags of *5/*0/***0kg net each.or according to your request
