HUPC Zirconia Silicate Grinding Beads is made by electric-fusion process. Compared to sinter beads and the similar others, It has more even internal crystallite structure. The middle density and hardness features are suitable for grinding slurry in viscosity from low to middle. It is widely used in grinding of coatings, inks, dyestuffs, kaolin, fillings etc.
