Character:
traits odorless and colorless transparent crystals (industrial microstrip yellow) . Mei-hardship. 2.261g/cm³ density. 306.8C melting point. Slightly deliquescence, almost non-caking, but in a very small amount of impurities in sodium chloride, sodium nitrate deliquescence nature is increasing dramatically. Dissolved in water, methanol, ethanol, ammonia is highly soluble in slightly soluble glycerol, dissolved in acetone very slim. When dissolved in water can absorb heat. Warming up to 380C above that break down into oxygen and sodium nitrite, 400 an 600C emit nitrogen and oxygen, 700Crelease nitric oxide, 775 ~ 865C when only a small amount of nitrogen dioxide and nitrogen oxide formation. With a total heat sulfate, and nitrate generation sodium bisulfate. Salts can play with the Minute decomposition. Yes oxidants. With wood, cloth, oils and other organic contact, can cause a fire and explosion.

Application:

Enamel Industrial applications for flux, oxidizers and for the preparation of enamel powder raw materials. For a variety of industrial glass and glass products, the bleaching agents, antifoaming agent to clarify flux oxidation agents. No hunger industrial caustic soda used for melting and the bleaching agent used in the manufacture of other nitrates. The food industry for the meat processing hair color agent to prevent meat qualities, and seasonings role to play. Apply fertilizer industry for quick-impact acidic soil fertilizer, particularly applicable must root crops, such as carrots, turnips, etc.. Dye industrial production picric acid dyes and raw materials. Steelmaking for the metallurgical industry, the heat treatment of aluminum alloys agent. As for the industrial metal cleaning agent and the preparation of ferrous metals Bluing agents. The pharmaceutical industry for the medium penicillin. Cigarette tobacco industry for the Combustion. Analytical chemistry for chemical reagents. In addition, for the production of explosives.
