补充资料：钙镁磷肥
分子式：
CAS号：

性质：又称熔融钙镁磷肥。一种微碱性、含有磷酸根的硅铝酸盐玻璃体。无明确的分子式与分子量。成品颜色有灰白、浅绿、墨绿、黑褐等。无毒、无臭、不吸湿、不结块，对包装材料无腐蚀。不同组成熔料，熔融温度相差甚大，可由1260℃到1500℃。黏度随温度的升高而降低：1266℃时为0.8Pa·s，1504℃时为0.183Pa·s。磷矿石、助熔剂(硅酸镁矿物，如蛇纹石、白云石、橄榄石加硅石)和燃料配制的炉料在工业(如高炉、电炉、平炉、旋风炉等)中于1350℃熔融，熔体用压力水水淬、沥水、干燥、磨细即得成品。为枸溶性磷肥，含有效P2O512％～25％，MgO 8％～25％，CaO 25％～40％。可作为磷、镁、钙肥施用于酸性(或微酸性)土壤，并可作为土壤改良剂。
