补充资料:碳氮化钙
CaCN2    分子量80.10
    无色六方晶系结晶体。工业品因含有碳素等杂质为深灰色粉末或颗粒。有电石或氨的气味。视密度0.9-1.1g/cm3。升华1090℃。熔点1300℃。遇水分解为氨气,体积增大,容易引起爆炸。有毒!人吸入后容易引起呼吸障碍发生痉挛。如含有杂质碳化钙或少量磷化钙时,遇水易自行燃烧。
    应用  农业上是-种碱性肥料。用于酸性土壤,既可中和土壤酸性,又可利用土壤酸性消除毒性,因在转化成尿素的过程中,中间产物对作物有毒性,一般只作为基肥,不能直接作追肥和种肥;如用于碱性土壤中,因分解缓慢,且易形成双氰胺,故不宜施用。也是一种生产高效低毒多菌灵农药、除草剂、杀菌剂、杀虫剂的主要原料。另外,还是有机工业和塑料工业的基本原料,用于生产双氰胺、三聚氰胺、氰熔体、硫脲、有机玻璃等。
