Potassium Silico Fluoride

1.Properties of potassium silico fluoride K2SiF6:

It is white crystals or powder, odorless, tasteless and weak acidic and have toxic. The density of hexagonal crystal is 3.08.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 silico fluoride K2SiF6:

It can be used as wooden preservatives and insecticides, or to produce synthetic mica and opalescent glass.It can also be used as flux in metallurgy of magnesium and aluminium.

3.Packing: Plastic lined woven bags of 25/50kg

4.Delivery time: 7-10 days after receiving your order.
