| 摘要: 某硼酸盐盐湖卤水经日晒蒸发到不同析盐阶段,分别取泻盐和钾盐饱和卤水在实验盐田中储存越冬.前者在天然冷冻析出泻盐之后,当卤水中硼含量达到1.69%MgB4O7,温度为-21℃时开始结晶析出MgO·3B2O315/2H2O.对于后者,当硼含量为2.43%MgB4O7,温度为-17℃时开始结晶析出MgO·3B2O3·15/2H2O. |

| Abstract: The brine taken from the borate salt lake is concentrated by solar evaporation to that it just begin to crystallize epsomite or potassium salt out. The different concentrated brine containing borate is transfered separately into experimental basin which is in the. field of the salt lakebefore winter is coming. The results show that MgO·3B2O3·15/2H2O canbe crystallized out from the brines which contains 1·69% MgB4O7 or 2.43% MgB4O7 when they are frozen to -21℃and -17℃ respectively during natural cooling in winter. |
