工业废弃物锆硅渣生产白炭黑

Preparation of silica white from the industrial waste of silica residue containing zirconium

研究用锆硅渣、含碱废液 ,由晶种法制白炭黑的工艺条件 .在最佳工艺条件下 ,二氧化硅的质量分数达到 91 .3 % ,产品质量符合GB1 0 5 1

The process conditions for preparation of silica white have been studied,which was made by inoculating crystal process with the silica residue containing zirconium and alkaline liguor.Under the optimum process conditions,the content of SiO 2 in the product comes up to 91.3%.The quality of the product can meet the requirement of Chinese standard GB10517-89.
