工业用钛粉原鉴定方法为化学分析，要测定近２０种低含量元素，工作量非常大。针对较多行业使用的钛粉只要求全钛含量或单质钛含量，本文提出用ｘ射线衍射法确定钛含量，此方法简便，且能确定单质钛含量，这是别的办法无法达到的。 Industrial titanium powder original identification method for chemical analysis, to determine nearly 20 kinds of low-content elements, the workload is very large. Titanium powder used for more industries only requires full titanium or elemental titanium content. In this paper, x-ray diffraction is used to determine the titanium content. This method is simple and can determine the content of elemental titanium, which can not be achieved by any other method.
