摘　　要：应用X衍射物相分析方法 ,确定贵州福泉钾钙肥产品中主要物相为KAlSiO4 、Ca2 SiO4 、Ca2 AlSiO7、CaAl2 O4 、Al2 SiO5等 ,其中KAlSiO4 为钾钙肥主要有效成分。通过红外光谱对原矿中钾长石 (K[AlSi3O8])及钾钙肥产品中KAlSiO4 的结构比较 。The main phase compositions of potassium-calcium fertilizer in Guizhou fuquan are KAlSiO 4?Ca 2SiO 4?Ca 2Al 2SiO 7?CaAl 2O 4 and Al 2SiO 5 ect ., which is determined by using X-ray diffraction phase analysis method.KAlSiO 4 in potassium-calcium fertioizer is main effective composition. The IR spectrum of K[AlSi 3O 8] in mineral is compared with that of KAlSiO 4 in product. the soluble mechanism of K + in potassium-calcium fertilizer is studied.
