高铝陶瓷原料的瓷坩埚熔样法及其测定

The Fusion Method of Ceramic Raw Materials High in Aluminum and the Determination

本研究采用价格低廉的瓷坩埚代替价格昂贵的铂坩埚,熔融高温难熔的高铝样品,并用带硅法测得氧化铝含量.其方法简便,分析结果准确可靠.可广泛应用于陶瓷生产及科研中的常规化学分析及学生实验.解决了长期以来高铝样品脱离不了铂坩埚,难熔难测的问题.

We research the method by porecelain crucible instead of plutinun cruciblesuccessfully to melt ceramic meterial.By this method,not only expensive platinum cruci-ble can be replaced by cheap porcelain crucible,but also the operation becomes simply,theanalytical results are accurete and reliable,On the othe hand,the high fusion point mate-rials containing high in aluminum can be also melted by using this method and aluminiumis determined,Thus,it can fit for students experiments and routine analysis of middle orsmall industrial euterprises widely.
