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.
Silicon nitride balls
Silicon nitride is a hard ceramic having high strength over a broad temperature range, moderate thermal conductivity, low coefficient of thermal expansion, moderately high elastic modulus, and unusually high fracture toughness for a ceramic. This combination of properties leads to excellent thermal shock resistance, ability to withstand high structural loads to high temperature, and superior wear resistance. Silicon nitride is mostly used in high-endurance and high-temperature applications, such as gas turbines, car engine parts, bearings and metal working and cutting tools.
ZrO2 density: 6.0 g/cm3 SI3N4 density : 3.20g/cm3 SIC density: 3.15 g/cm3
Hardness: 85-90 bending strength: 2750 N/mm2, wear resistance and toughness.
Zirconia balls also feature resistance to abrasion and corrosion and are chemically inert to molten metals, organic solvents, caustics, and most acids. In addition, zirconia balls maintain high strength at temperatures up to 982ºC (1800 ºF). Some sizes are available from stock; others may be manufactured to your specifications.
Zirconia balls can be used for: 1. grinding and dispersion of coatings and paints. 2. organic/inorganic pigments, e.g. titanium dioxide, ultra marine, iron oxide, etc. 3. pigments to dye textiles, plastics and food. 4. electric ceramics, e.g. barium titanate, piezoelectric ceramics, sensors, condensers. 5. medical technology, e.g. dentures and hip prosthesis. 6. magnetic ceramic, ferrite. 7. technical ceramic components, e.g. exhaust cultivator in engine technology. 8. dispersion of fungicides, herbicides, insecticides. 9. grinding of pigments and solids for lipsticks, skin and sun protection creams. 10. nano grinding for the production of active substances and supplies substances. Recommendations for grinding applications 1. in high energy mills, like pin-mills. 2. for water-based milling products with low viscosity, low solids - like ink-jet. 3. in the food industry, for pharmaceutical products and cosmetics..
