近年来,铌、钽矿床形成的地球化学及地质特征方面的研究,提供了不少资料。因而促进了这方面实验工作的开展。目前最重要的问题之一,是研究铌、钽的迁移形式以及迁移和沉淀的物理化学条件。 В.П.帕舒京,Б.П.索鲍列夫(1963)首先研究了钽在超临界(气)溶液中的迁移形式。他们采用50毫升体积的直筒高压釜进行实验,釜内装有两个坩埚。一个装有K_2TaF_7的坩埚放在高压釜的底部;另一个装有捕集剂Ca(OH)_2的坩埚悬挂在釜
In recent years, niobium, tantalum deposits formed geochemical and geological characteristics of the research, provided a lot of information. Thus promoting the experimental work in this area. One of the most important issues now is to study the migration patterns of niobium and tantalum and the physico-chemical conditions of migration and precipitation. В.П. 帕舒 京, Б.П Sobolev (1963) first studied the migration of tantalum in supercritical (gas) solutions. They used a 50 ml autoclave autoclave, which contained two crucibles. A crucible containing K_2TaF_7 was placed on the bottom of the autoclave. Another crucible containing Ca (OH) _2 was suspended from the autoclave
