该课题的任务较多,我院承担了“兰钨相组成的定量分析方法,兰钨的制取及其氢还原的工艺基础理论研究”。具体包括下述三方面内容: 1.兰钨相组成的定量分析方法; 2.兰钨相组成与工艺参数的关系; 3.兰钨相组成对钨粉粒度的影响。 钨的兰色氧化物,简称兰钨,是钨冶金过程中的一种重要的中间产物。工业兰钨一般为多相物质的混合物。兰钨的相组成对其性质及后续产品的质量有显著影响。 制取含α-W和WO_2两相物质的标样。利用该标样,并借助于未知试样的含氧量数据,可以对含α-W、β-W和WO_2三相物质的未知试样进行X射线有标定量相分析。本研究还提供了制取铵钨青铜(ATB),ATB+W_(20)O_(58)等标样的方法。至此,可以对兰钨中的各相进行X射线有标定量相分析。
The task of the task more, our hospital assumed the “blue tungsten phase quantitative analysis of the composition, preparation of blue tungsten and hydrogen reduction process based on theoretical research.” It includes the following three aspects: 1. Quantitative analysis of the composition of the blue tungsten phase; 2. The relationship between the composition of the blue tungsten phase and the process parameters; 3. The influence of the composition of the blue tungsten phase on the particle size of the tungsten powder. Tungsten blue oxide, referred to as lantern tungsten, is an important intermediate in tungsten metallurgy. Industrial tungsten is generally a mixture of heterogeneous substances. The phase composition of blue tungsten has a significant effect on its properties and the quality of subsequent products. Preparation of standard samples containing α-W and WO_2 two-phase material. Using this standard, and with the aid of the oxygen content data of unknown samples, it is possible to perform X-ray stationary phase analysis of unknown samples containing α-W, β-W and WO 2 three-phase materials. This study also provided the preparation of ammonium tungsten bronze (ATB), ATB + W_ (20) O_ (58) and other standard samples. Up to this point, X-rays can be calibrated for each phase in blue tungsten.
