二十年来,核纯氧化铍中硅的测定都是用化学分析法,鉴于打开矿样难度较大,因此不能当天报结果,对于指导生产极为不利.而且核纯氧化铍中其它19个杂质元素都是以氧化铍粉末直接以发射光谱激发测定,硅的分析是否也能归纳到核纯氧化铍的杂质全分析方法中,对此,我们作了大量的试验工作。 In the past 20 years, the determination of silicon in pure beryllium oxide was carried out by chemical analysis. In view of the difficulty of opening the ore sample, it was not possible to report the result on time and was extremely unfavorable to the guide production. Moreover, the other 19 impurity elements in the nuclear pure beryllium oxide All of this is based on the direct analysis of the emission spectra of beryllium oxide powder and whether the analysis of silicon can be summed up in the method of total impurity analysis of pure beryllium oxide. To this end, we have done a lot of experiments.
