摘要
本方法采用同一份分析试液测定镁铬质耐火材料中的铬、钙、镁、铁、铝 5种元素 ,铬用高氯酸直接氧化测定 ,钙、镁不需分离直接测定 ,铁。
The article introduces a determining method about contents of Cr,Ca,Mg,Fe & Al in magnesite—chrome refactories by use of only one analysis preparation:Cr is determined after direct oxidation by perchloric acid;Ca & Mg are directly determined without any separation;and Fe & Al by continuous titration.
