Production and properties of Cr2O3 Raw Material for Refractories
摘要
There are many processes to produce Cr2O3 from chrome-ores,Different particle size ranges of Cr2O3 powder,fine pinment grade green Cr2O3 and coarse metallurgy grade black Cr2O3, are made by different processes in China,Green Cr2O3 as superfine and addition and metallurgy grade black Cr2O3 used to synthesize Cr2O3 grain can be applied to refractories.It is very difficult for high purity Cr2O3 to sinter to densification and TiO2 addition is contributed to densification of Cr2O3 sintered at high temperature,Cr2O3 grains with relative density of 91%-95% are gained by sintering Cr2O3 with TiO2 addition and electrofusing Cr2O3 raw materials.
