| 摘 要： | 用矾土标准物质、白云石标准样品、基准氧化铝及优级纯氯化钾和氯化钠作为基本材料,并应用Excel公式算法求得上述各物质的准确质量,配制成一组包括各被测组分的质量分数呈梯度分布的12种混合物,分别将上述各混合物置于铂-金坩埚中与无水四硼酸锂熔融,所得玻璃状熔块即为自制的一组供X射线荧光光谱分析刚玉质耐火材料用的系列标准样品。按所给的各分析通道的参数,测定了此类耐火材料中8项组分(即SiO2、Al2O3、MgO、Na2O、K2O、Fe2O3、CaO及TiO2)。另取基准氧化铝一份,按试验方法作空白试验,从而消除其中可能存在的痕量杂质的干扰。将所配制的系列标准样品应用于实样分析,所得8项组分的测定结果与用化学分析法所测得结果相符,其测定值的相对标准偏差(n=10)均小于12%。

| Abstract: | A series of mixtures of the CRM or standard sample of alumina and dolomite,primary standard of aluminum oxide and extrapurity potassium chloride and sodium chloride,with their exact masses obtained by applying the Excel formula algorithm,was prepared,and fused with anhydrous lithium tetraborate in a Pt-Au crucible.The 12 pieces of glassy melts obtained formed a series of standard samples having the contents(w%) of their components(i.e.,SiO2,Al2O3,MgO,Na2O,K2O,Fe2O3,CaO and TiO2) distributed in gradients,and... |
