The results show that under the condition of the experiments, the high KOH concentration is benefit to the formation of soluble niobate, but the high temperature is favor of the formation of insoluble niobate, and the insoluble tantalate is the sole leachin...

而KOH浓度一定，温度升高，有利于生成偏铌酸钾。浸出时间过长也将促使不溶性偏铌酸钾的形成。试验条件下，Ta2 O5在KOH高浓介质体系中只得到不溶性的偏钽酸钾。Nb2 O5和Ta2 O5混合物的浸出规律与纯Nb2 O5类似，铌、钽不能被选择性地浸出。

Catalyst The catalyst consists of oxygenated compounds of tellurium, cerium and molybdenum supported on a microspheroidal silica carrier.
