硝酸钠是具有多种用途的化工产品,主要用于化学、玻璃、冶金,机械等工业。食品、医药、电子以及矿山炸药也大量使用。全国年产量目前约6万吨,随着工业生产的发展,尤其是一些新产品的涌现,过去很多用硝酸钾为原料的工业产品逐渐用硝酸钠代替,故目前国内产量仍处在供不应求的状态。为满足市场需要,有些生产厂对生产工 Sodium nitrate is a chemical product with many uses. It is mainly used in chemical, glass, metallurgy, and machinery industries. Food, medicine, electronics, and mine explosives are also widely used. The annual output of the country is about 60,000 tons. With the development of industrial production, especially the emergence of new products, many industrial products using potassium nitrate as raw materials have gradually been replaced with sodium nitrate. Therefore, domestic production is still in a state in short supply. . In order to meet market needs, some production plants
