High precision zirconia balls are available in many sizes. Zirconia balls are most commonly used as check valves in flow control applications. When subject to stress by impact, grinding, or cracking, a zirconia ball undergoes “transformation toughening” which stops cracks from spreading and actually makes the ball stronger in the stressed area than what it was originally.
Zirconia balls also feature resistance to abrasion and corrosion and are chemically inert to molten metals, organic solvents, caustics, and most acids.
