本法采用在隋性气氛保护下用稀硫酸分解试样,定量地将固溶钛和钛的化合物进行分离。酸法处理后的残留物用硝酸、高氯酸及硫酸处理,可分别测出钛的碳化物,硫化物及氮化物含量。其钛化合物中各元素分析结果所计算出来的钛含量与实测的碳、硫化舍物中钛的含量一致,说明其结构为TiC、TiS即Ti_2CS,,与电镜观察结果一致,并与工艺条件和其他物理性能基本相符。
This method is used under inert gas atmosphere with dilute sulfuric acid decomposition of the sample, quantitatively the solid solution of titanium and titanium compounds were isolated. Residues after acid treatment were treated with nitric acid, perchloric acid and sulfuric acid to determine the contents of carbides, sulfides and nitrides respectively. The titanium content calculated from each elemental analysis result of its titanium compound is consistent with the measured content of titanium in the measured carbon and sulfurous building materials, indicating that the structure is TiC, TiS is Ti_2CS, which is consistent with the observation by electron microscope and is in good agreement with the process conditions and Other physical properties basically match.
