Chinese name： Industrial Sodium Nitrate (NaNo3)
English name： Sodium nitrate
Product Category： Inorganic Chemicals / Inorganic Salt
CAS NO： 7631-99-4
EC NO： 231-554-3
UN： 1498
Molecular formula： NaNO3
Property: White fine crystal. Some are light gray or buff. The relative molecular weight is 84.99 and density is 2.257. It's easy to be deliquescence and to dissolve in water and liquid ammonia, but only a little can dissolve in ethanol and glycerin. The melting point is 271°C. And decomposition temperature is 3801. Its decomposition products are sodium nitrite and oxygen. If heated to higher temperature, it will be decomposed into the mixed gas of oxygen, azote and oxynitride.lt has the strong oxidizing property and can cause the inflammation and explore while mixed with organics, sulfur and sulfite, etc.
This product is important chemical raw material, which is widely used in glass, dye, detonator, metallurgy, machinery and vitreous enamel and other industries.
(1)This product shall be stored in the place of ventilation and dry, avoiding rain, heated and exposure under sunlight.
(2)This product shall not be delivered or stored together with acid, metal powder, saw dust, gauze, paper, sugar, sulfur, and other organic tinder and regulated.
(3)Handle with care against friction and bounce while moving and piling.
(4)The fire caused by sodium nitrate can be eradicated by pouring water.

物理性质
相对密度：2.26
熔点（℃）： 308
溶解性： 1g溶于1.1ml水、0.6ml沸水、125ml乙醇、52ml沸乙醇、3470ml无水乙醇、300ml无水甲醇，还溶于液氨和甘油。
化学性质
溶解于水时能吸收热。加温到380℃以上即分解成亚硝酸钠和氧气，400一600℃时放出氮气和氧气，700℃时放出一氧化氮，775～865℃时才有少量二氧化氮和一氧化二氮生成。与硫酸共热，则生成硝酸及硫酸氢钠。与盐类能起复分解作用。是氧化剂。与木屑、布、油类等有机物接触，能引起燃烧和爆炸。
化学表达式NaNO3。
