Hemispheric Yttria Stabilized Zirconia Beads For Grinding Wear Resistant
Wear resistant zirconia hemispheric beads use for valve or pump
Description:
Zirconia ceramic, also known as zirconium oxide (ZrO2), is a white crystalline oxide of zirconium. Its most naturally occurring form is the mineral baddeleyite with a monoclinic crystalline structure.
Zirconia has the highest strength and toughness at room temperature of all the advanced ceramic materials. Zirconia oxide ball offers superior load bearing capability,easily polished to finer surface finishes.
Our company Zirconia ball manufacturing capability ranges in size from 0.5mm to 50.8mm
