High Quality Sodium Nitrate Powder Crystal Industrial Grade NaNO3 For Glass Dye
Sodium nitrate has a melting point of 306.8°C and a density of 2.257 g/cm3 (at 20°C). It is colorless, transparent or white with yellowish rhombus crystals. Its taste is bitter and salty, easily soluble in water and liquid ammonia, slightly soluble in glycerin and ethanol, and easily deliquescent, especially when it contains a small amount of sodium chloride impurities, the deliquescent of sodium nitrate is greatly increased. When dissolved in water, the temperature of the solution decreases and the solution becomes neutral. When heated, sodium nitrate is easily decomposed into sodium nitrite and oxygen. Sodium nitrate can support combustion and must be stored in a cool and ventilated place. It is oxidizing. It can cause combustion or explosion when rubbing or impacting with organic matter. It is toxic.
