对含硼浓缩盐卤在冷冻析除一般盐类后在放置过程中析出的一种硼酸镁盐进行了研究。经化学分析、热分析、X射线粉晶衍射和红外光谱鉴定,结果表明是MgO·3B_2O_3·7~(1/2)H_2O。同时还确定同一浓缩卤水在室温(20℃)到-20.5℃温度范围内析出同一硼酸盐结晶
A kind of magnesium borate salt precipitated during the placement of boron-enriched salt brine after freeze-drying general salts was studied. The results of chemical analysis, thermal analysis, X-ray powder diffraction and IR spectroscopy showed that it was MgO · 3B 2 O 3 · 7 ~ (1/2) H 2 O. It is also confirmed that the same concentrated brine precipitates the same borate crystal within a temperature range of from room temperature (20 ° C) to -20.5 ° C
