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: High whiteness and Features: 1. High hardness. 2. High wear resistance. Alumina ceramic is the material of choice for alumina wear parts. 3. Good tenacity, impact-endurable, no break under high speed impact. 4. Higher density than any other grinding bead brings higher grinding efficiency, thus allowing higher solid proportion or increased material flow. The main advantages of ZrO2 ceramic ball to steel balls are: 1. It is 23% lighter than the steel ball, which reduces the centrifugal force, rolling and wear of the channel during high-speed and accelerated operation of the bearing; 2. The friction coefficient is small and the rotation flexibility is good; 3, high temperature resistance, the use temperature can reach 750 C, more resistant to chemical corrosion than steel; 4, can work under the conditions of no oil lubrication; no metal pollution; no magnetic; electrical insulation.

Zirconia ceramics are white, yellow or gray when containing impurities, and generally contain HfO2, which is difficult to separate. There are three crystal states of pure ZrO2 at atmospheric pressure. The production of zirconia ceramics requires the preparation of high-purity, well dispersed, ultrafine particles and narrow particle size distribution powders. There are many methods for the preparation of zirconia ultrafine powders. The purification of zirconia mainly includes chlorination and thermal decomposition, alkali metal oxidation decomposition, lime melting, plasma arc, precipitation, colloid, hydrolysis, spray pyrolysis, etc.
