摘要： 以氯化钙、四硼酸钾为原料,以水为溶媒,采用易于工业化、无污染的水溶液法制备一种新型硼酸钾钙复盐.该方法工艺条件为:去离子水450ml,四硼酸钾和氯化钙的质量比65∶7.5,搅拌转速400r/min,45℃反应3h.通过化学分析、红外光谱、X射线衍射、扫描电镜等分析测试方法,对所合成的复盐进行了分析和表征.考察了反应温度对晶体形貌的影响.结果表明:所采用的工艺条件是合适的,制备的K2O.CaO.4B2O3.12H2O硼酸钾钙复盐晶型发育良好、形貌规整.反应温度的不同会使硼酸钾钙复盐的形貌发生改变.

Abstract: Using CaCl2 and K2B4O7 as raw materials, K2O · CaO · 4B2O3 · 12H2O was synthesized from aqueous solution. Conditions were as follows: water 450 ml; mass ratio of K2B4O7: CaCl2 was 65:7.5; reaction temperature 45°C; stir speed 400 r/min; reaction time 3 h. The product was analyzed and characterized by chemical analysis, FT-IR spectra, X-ray powder diffraction and SEM. The result showed the reaction conditions were appropriate and varying reaction temperature affected growth inhibition of dissimilar K2O · CaO · 4B2O3 · 12H2O. K2O · CaO · 4B2O3 · 12H2O was a rhombic crystal about 4 mm long. The shape of K2O · CaO · 4B2O3 · 12H2O crystal was well and integrated.
