Ceramic ball has the characteristics of high temperature and high pressure resistance, high mechanical strength, good wear resistance and stable chemical properties. It can withstand acid, alkali and other organic solvents corrosion, and can withstand the production process temperature changes. Therefore, it is widely used in machinery, electronics, chemical industry, aerospace and other fields.
Ceramic balls usually made in Silicon Nitride and Zirconia and Alumina and Silicon carbide materials.
Alumina Ceramic Balls,
Seal out air and gas in high-temperature and high-wear applications. This ultrahard ceramic can also be used in applications that require superior strength.
Silicon Nitride Ceramic Balls,
It often used to create bearings, silicon-nitride ceramic is harder than many types of bearing steel but is lightweight and can be easily polished. It also withstands high temperatures.
Zirconia Ceramic Balls,
It usually used instead of metal in bearings and rollers, these balls are ideal for applications where strength under heavy loads and wear resistance is needed. It’s the addition of yttria that gives this zirconia more strength and lowers the chances of cracking from impact than standard zirconia, alumina, and silicon nitride ceramic. If cracks do occur, they will not spread, extending the life and reliability of the material. It also means this zirconia blend resists wearing down from rubbing against another part or abrasion from chemical slurries.
Silicon-Carbide Ceramic Balls,
Extremely hard with excellent corrosion resistance, this silicon-carbide ceramic is often used for rubbing parts such as bearings and bushings in chemical-processing environments. This material’s hardness means it resists abrasion and wear, but also makes it more brittle than other ceramics. Don’t use it under heavy loads or at high speeds. Nearly chemically inert, it resists corrosion better than other ceramics when in contact with acids and other chemicals. Silicon-carbide ceramic conducts heat well and doesn’t expand significantly from heat, so it won’t deform or crack from temperature swings. Rated for use at up to 2550° F, it’s good for use in furnaces and refractories.
