Description: White powder, insoluble in water, soluble in acid. It is very easy to absorb moisture and can quickly absorb moisture and carbon dioxide in the air. It should be placed in a sealed container. | Description: White powder, insoluble in water, soluble in acids, As it is highly hygroscopic and absorb the moisture and carbon dioxide from air rapidly, it should be kept in sealed containers. Uses: Used as the raw material of the industries of glass, ceramics and electronics. | ||
