Acid-Resistant Silicon-Carbide Ceramic Balls
- Color: Black
- Max. Temperature: 2,550° F
- Fabrication: Sintered
- Porosity: 0.2%
- Compressive Strength: 350,000 psi
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.
