Embodiment 2: a kind of quantitative analysis method of elemental silicon content in industrial silicon slag, concrete steps are as follows:
(1) The industrial silicon slag is broken and ground into an average particle size of 200 mesh silicon slag powder, and the weight of the silicon slag powder is 10g;
(2) The silicon slag powder is subjected to hydrochloric acid acid leaching for 2 hours to dissolve silicate to obtain an acid leaching solution containing silicic acid and solid particles containing elemental silicon and silicon carbide. Dry under vacuum, weigh the solid particle mass m2 containing elemental silicon and silicon carbide to be 3.76g; wherein the solid-liquid ratio g:ml of silicon slag powder and hydrochloric acid is 1:2;
(3) Slowly add nitric acid to the solid particles containing elemental silicon and silicon carbide, and then add hydrofluoric acid drop by drop to make the elemental silicon react with the mixed acid of nitric acid and hydrofluoric acid for 1.5h, dissolve in nitric acid and hydrofluoric acid The acid dipping solution containing silicofluoric acid and silicon carbide solid particles were obtained in the mixed acid, the silicon carbide solid particles were vacuum-dried at a temperature of 60°C, and the mass m3 of the silicon carbide solid particles was weighed to be 2.52g; the nitric acid and hydrofluoric acid The volume ratio is 1:1, and the solid-to-liquid ratio g:ml of solid particles containing elemental silicon and silicon carbide to nitric acid is 1:24, and the solid-to-liquid ratio g:ml of solid particles containing elemental silicon and silicon carbide to hydrofluoric acid: ml is 1:24;
(4) calculate respectively the quality m4 of silicate and the quality m5 of elemental silicon in the silicon slag powder according to the weight difference method,
The quality m4=m1-m2=6.24g of silicate, the quality m5=m2-m3=1.24g of elemental silicon, then calculate the mass percentage content of silicate, elemental silicon and silicon carbide in the industrial silicon slag respectively;

(2) The silicon slag powder is subjected to hydrochloric acid acid leaching for 3 hours to dissolve silicate to obtain an acid leaching solution containing silicic acid and solid particles containing elemental silicon and silicon carbide. Dry under vacuum, weigh the solid particle mass m2 containing elemental silicon and silicon carbide to be 2.78g; wherein the solid-liquid ratio g:ml of silicon slag powder and hydrochloric acid is 1:2;
(3) Nitric acid is slowly added to the solid particles containing elemental silicon and silicon carbide, and then hydrofluoric acid is added drop by drop to make the elemental silicon react with the mixed acid of nitric acid and hydrofluoric acid for 3 hours, and dissolve in the nitric acid and hydrofluoric acid. The acid dipping solution containing silicofluoric acid and silicon carbide solid particles were obtained in the mixed acid, and the silicon carbide solid particles were vacuum-dried at a temperature of 60° C., and the mass m3 of the silicon carbide solid particles was weighed to be 1.11 g; wherein the nitric acid and hydrofluoric acid The volume ratio is 1:1, the solid-liquid ratio g:ml of solid particles containing elemental silicon and silicon carbide to nitric acid is 1:15, the solid-liquid ratio g:ml of solid particles containing elemental silicon and silicon carbide to hydrofluoric acid is 1:15;
(4) Calculate the quality m4 of silicate and the quality m5 of elemental silicon in the silicon slag powder respectively according to the weight difference method, the quality m4=m1-m2=7.22g of silicate, the quality m5=m2- of elemental silicon m3=1.02g
