| 摘 要： | 含铬耐火材料中的SiO2,Al2O3,Fe2O3,TiO2,CaO,MgO和Cr2O3等直接影响着产品质量,属于需控制成分。文章用市售耐火材料标准品和基准试剂配制出适当含量范围且有一定梯度的系列标准样,以四硼酸锂-偏硼酸锂(质量比67∶33)作熔剂、熔样过程中添加碘化铵固体脱模剂的方法制备样品玻璃熔片,通过X射线荧光光谱法(XRF)测定元素的荧光强度,并以理论α系数基体校正法消除吸收与增强效应,从而得到测量上述组分的定量校正曲线。该方法应用于耐火材料标准品的测定,所得结果与标准值吻合。应用于实际样品的测定并和化学法比较,结果准确,精密度好,操作简单、快速,具有良好的实用性。

| Abstract: | Components like SiO2,Al2O3,Fe2O3,CaO,MgO and Cr2O3 dominate the performance of chromium-containing amorphous refractory.That's still a hard task for product evaluation and quality control for amorphous refractory due to various component content,less available standard product and difficulty in fusion bead preparation.In the present study,series calibration standards were made from reagents and marked standards depend upon the content of components in real samples.The fusion bead was prepared with lithium t... |
