摘要
使用XRD、DTA、VSM和穆斯堡尔谱等分析测试手段 ,对在不同气氛下晶化热处理的含少量的B2 O3、P2 O5钙铁硅微晶玻璃的晶相结构和性质进行了比较深入的研究。研究结果表明 ,在氧化性气氛下热处理的钙铁硅微晶玻璃以赤铁矿为主 ;
The phase composition and properties of calcium iron silicate glass-ceramics containing minor B 2O 3 and P 2O 5, heat-treated in different atmosphere, were investigated with DTA, XRD, VSM and mossbauer spectrum. The results showed that hematite was its main crystalline of the calcium iron silicate heat-treated in oxidation atmosphere.Only if it was heat-treated in reduction atmosphere could the ferromagne- tic glass-ceramic, whose main crystalline was magnetite,be prepared.
