(2) dry powder sodium nitrate: white crystal,non-caking, showing loose status.
Density:2.168. No odor, slightly salty. It is liable to deliquesce, dissolved in water,
soluble in liquid ammonia,slightly soluble in ethanol and glycerin,Melting Point:271℃. Decomposition temperature is
320℃，It has oxidability and also has reducibility. It will slowly be oxidized into sodium nitrate in atmosphere, it can form nitrogen compound with nitrilo at low temperature.
