Zirconium Silicate Balls NanorZr-64B  are shaped with granulating and compacting press method and sintered at high temperature in a kiln. The compacted and homogenous microstructure of zirconium silicate to form a tough and non porous woking surface. Due to the lower wear rate, middle density and higher toughness strength, it is suitable to millling low to middle density slurries which refuse the alumina contamination.
