Products Description

Aiming at the problem that the elemental silicon content in the complex silicon slag phase cannot be analyzed in the prior art and affects the recycling of silicon slag, a quantitative analysis method for the elemental silicon content in industrial silicon slag is provided. The present invention can be used for the determination of the elemental silicon content in silicon slag Quantitative analysis and determination can obtain the mass percentage content of silicate, silicon carbide and silicon in silicon slag, so as to facilitate the recovery and treatment of silicon slag, obtain the content of elemental silicon in silicon slag efficiently and accurately, and solve the problem of silicon slag recycling. And the problem that the content of elemental silicon cannot be quantified in the process of sales, it is convenient to realize the utilization of silicon slag points. This method is simple in process, easy to operate, high in efficiency, and can accurately quantify the content of industrial silicon in silicon slag.

A method for quantitative analysis of elemental silicon content in industrial silicon slag, the specific steps are as follows:

(1) Crushing and grinding industrial silicon slag into silicon slag powder with a particle size of 100-300 objects, weighing the silicon slag powder mass m1;

(2) Add excess hydrochloric acid to silicon slag powder for acid leaching to completely silicate to obtain acid leaching solution containing silicic acid and solid particles containing elemental silicon and silicon carbide, and vacuum-dry the solid particles containing elemental silicon and silicon carbide , weigh the mass m2 of solid particles containing elemental silicon and silicon carbide;

(3) Add excess nitric acid and excess hydrofluoric acid in sequence to solid particles containing elemental silicon and silicon carbide for secondary acid leaching to completely dissolve silicon to obtain acid leaching solution containing silicofluoric acid and solid particles of silicon carbide, silicon carbide Dry the solid particles in vacuum, then weigh the mass m3 of the silicon carbide solid particles;

(4) Calculate the mass m4 of the silicate in the silicon slag powder and the mass m5 of the elemental silicon according to the weight difference method, and then calculate the mass percentages of the silicate, elemental silicon and silicon carbide in the industrial silicon slag respectively .
