NaNO3 Sodium Nitrate Used as Raw Material for Preparing Enamel Powder
Sodium nitrate is colorless, transparent or white with slightly yellow rhombus crystals. It tastes bitter and salty. It is easily soluble in water and liquid ammonia, slightly soluble in glycerol and ethanol, and is easily deliquescent. Especially when it contains a very small amount of sodium chloride impurity, the deliquescent property 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.
