本文提出用H_2O_2-NaOH溶解鸽粉,同时实验了钨对硅发色的影响,拟定出快速测定钨及三氧化钨中硅的方法,可测下限为,钨粉中硅,0.02%;三氧化钨中硅0.006%。
In this paper, it is proposed to use H 2 O 2-NaOH to dissolve pigeon and experimentally study the effect of tungsten on the color development of silicon. A rapid method for the determination of silicon in tungsten and tungsten trioxide is proposed. The measurable lower limit is that silicon in tungsten powder is 0.02% Tungsten silicon 0.006%.
