Yttrium Stabilized Zirconium Oxide Beads

Product Description This is Lifeng Y-TZP yttrium stabilized zirconium oxide beads, which is made of top quality zirconia powder, suitable for any kinds of mills such as ball mill, sand mill, attritor mill and vibratory mill.   Applications Electronics Industry: Piezoelectric ceramics, inductance materials, capacitors ceramics, semiconductor ceramics, etc.. Battery Industry: Lithium iron phosphate, cobalt acid lithium materials, etc.. Chemical Industry: Paint, materials, printing ink, pigments, etc.. Ceramic Industry: Refractory materials, glaze materials, silicic acid zirconia, structural ceramics, etc.. Other Industry: Food, Medicine, Cosmetics     Features 1. Glossy satin smooth surface 2.  Excellent tanacity & impact-resistance, making the beads keep fine in high rotation speed 3. Low friction coefficient makes lower abrasion to the equipment. 4. Y-TZP grinding media is over 30-50 times longer life than glass beads 5. Y-TZP grinding media is 5 times longer life than zirconium silicate beads. 6. Higher density than other grinding media 7. Y-TZP's grinding efficiency is 6-8 times than glass beads, 2-3 times than zirconium silicate beads.     Specifications
