摘　　要：本文模拟库水硼镁石形成的地质条件,并根据掺杂作用原理,控制试剂用量和pH值,运用溶解、变温、蒸发、静置、稀释、冷冻等方法进行合成,并对其产物进行扫描电镜分析、X射线衍射分析和化学分析。根据库水硼镁石的热化学性质,在样品中掺入少量Eu_2O_3(纯度99.99%),在770℃条件下使其脱水重结晶,然后测定产物的激发光谱与发射光谱。Kurnakovite(2MgO·3B_2O_3·15H_2O)has been synthesized. The amount of reagents added and the pH value of the mixture are controlled according to the chanza (i. e. mixing principle. Processes such as dissolving, heating,evaporating,diluting, freezing and setting are used. Geological surroundings and physico-chemical conditions of the formation of kurnakovite are discussed. Kurnakovite has been dewatered and doped with Eu^(3+). Its Luminescence properties are also studied.
