一、前言陶瓷原料中极大部分为含水铝硅酸盐矿物,而这类矿物极大多数不能被酸所分解,故这类矿物的化学分析是比较复杂的。在试样分解中,常用HF分解或用无水碳酸钠高温熔融分解。为了避免氟离子的腐蚀,熔融器皿均需用耐高温而价格昂贵的铂坩埚(或 First, the foreword A large part of ceramic raw materials for the water-containing alumino-silicate minerals, and most of these minerals can not be acid decomposition, so the chemical analysis of such minerals is more complicated. In the decomposition of the sample, commonly used HF decomposition or high temperature melting anhydrous sodium carbonate decomposition. In order to avoid fluoride ion corrosion, melting containers are required with high temperature and expensive platinum crucible (or
