【摘要】 对三元体系K+,Mg2+/B4O2-7-H2O25℃的溶解度进行了研究,该体系属简单共饱型,两段溶解度曲线对应于体系的两种原始组分K2B4O7·4H2O、MgB4O7·9H2O的结晶区,共饱点组成为K2B4O713 96%,MgB4O70 53%。更多还原

【Abstract】 The result of study on the ternary system K⁺,Mg²⁺/B₄O^2-₇-H₂O at 25℃ has been reported. The system is of a simple eutectic type. The solubility isotherm of the system consistes of two branches and has two crystallization areas,corresponding to MgB₄O₇·9H₂O and K₂B₄O₇·4H₂O. The composition of the eutectic point is 13.96 weight percent of K₂B₄O₇ and 0.53 weight percent of MgB₄O₇,respectively.更多还原
