And high-grade silicate materials raw materials , manufacturing method of the high -grade silicate materials raw materials

摘要

The present invention , high solubility and high-grade silica materials for fertilizers raw materials , to provide a method of manufacturing high-grade silica material feedstock . Even a flammable organic content in the self- combustion ( exothermic reaction ) or look shell even chaff to enhance the furnace atmosphere temperature was burned off to increase the content of the inorganic fraction of the actual shell is allowed to continue the exothermic reaction of the chaff also substantially burn off the flame retardant organic fraction remaining on the surface of the chaff , the non- crystalline silica (SiO ₂) the content of by increasing to improve the solubility of the .
