硼钙锡矿的水热合成

HYDROTHERMAL SYNTHESIS OF NORDENSKILDINE

本文报道了硼钙锡矿的水热合成及其鉴定步骤。文中侧重于在一定温度和压力条件下,溶液介质中的阳离子组成对硼锡矿物生成种类影响的研究。实验结果表明:当溶液中铁、锰活度较高时,硼钙锡矿会被铁镁方硼石类矿物所替代;而较小的铝、硅活度则不影响其矿物相种类的变化。

Nordenskildine——CaSn(BO_3)_2 was hydrothermally synthesized at 400-475℃ and 5.066 MPa. Experimental results show that nordenskildine will be replaced by ericaite in the case of high activity of Fe and Mn in the solution, while relatively low aetivity of Al and Si would exert no influence on the formation of borate mineral assemblage.
