Features Specifications:Zirconia Beads (Y-TZP)  TZP Ceramic Beads has high density and toughness and super hardness, so it has better grinding efficiencies compared with other grinding media such as Alumina and Agate. The high wear-resistant TZP Ceramic Beads prevents materials from being contaminated and chemical etching or short service life of the grinder.  These special features make TZP Ceramic Beads especially suitable for material grinding in important occasion. Product Features Product Features Preventing material from contamination High grinding efficiency Suitable for high viscosity, wet grinding and dispersion So it's tougher and more resistant to wear and deterioration from a long term point of view.
