High Level Alloy Silicon Slag
Products Description
Potash fertilizer was synthesized using hot metal silicon slag and potassium carbonate as raw materials, and the crystallization properties of the potash fertilizer samples were analyzed using X-ray diffraction; the effects of potassium oxide addition, heating temperature, insulation time, cooling method and oxide addition type on the crystallization properties of the synthesized potash fertilizer were investigated. Potash fertilizer can be synthesized using hot metal desiliconized slag and potassium carbonate as raw materials; the synthesized potash fertilizer is composed of a potassium-containing crystalline phase Ca1.917K0.166SiO4, a non-potassium-containing crystalline phase Ca2SiO4 and a potassium-containing non-crystalline phase; various factors have no obvious effect on the crystallization properties of the synthesized potash fertilizer

Products cooperation picture
1.A harmless treatment method for methylchlorosilane monomer silicon slag. The methylchlorosilane monomer silicon slag is added to a closed stirring reactor, and is sequentially acid-washed, water-washed, alkaline-washed, and finally washed with a surfactant, filtered by a plate-frame filter press, and dried and discharged by a dryer. The harmless treatment method for methylchlorosilane monomer silicon slag overcomes the shortcomings of single acid washing or alkaline washing in the prior art, and adopts a combination of acid washing and alkaline washing to obtain a neutral silicon slag after treatment; finally, it is washed with an anionic surfactant, which not only greatly shortens the time cost, but also solves the problem of treating methylchlorosilane monomer silicon slag with a high copper content as hazardous waste at room temperature, and realizes the harmless treatment of methylchlorosilane monomer silicon slag. At the same time, the filtrate after washing the silicon slag can be recycled after copper extraction and desalination treatment, saving water resources.
