zirconium dioxide
4.Some new technological measures,such as new reactors,gel method to remove silicon,direct dissolve acid to recrystallizate and direct calcine from zirconyl chloride,were used to reform zirconium dioxide production process.As a result,the materials consumption and energy consumption were reduced and the wastewater discharge was decreased.Meanwhile the rubbish were recovered and utilized to prepare into a by-product as silica aerosol.The pollution prevention and control in production process were achieved.
