Fracture- and Thermally Shock-Resistant Silicon-Nitride Ceramic Balls
- Color: Black
- Max. Temperature: 1470° F
- Porosity: 13%
- Compressive Strength: 550,000 psi
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.

Extra-Strength Fracture- and Thermally
Shock-Resistant Silicon-Nitride Ceramic Sheets
- Color: Gray
- Maximum Temperature: 1,830° F
- Fabrication: Fired
- Dielectric Strength: 254V/mil
- Porosity: 0%
- Compressive Strength: 580,000 psi
Pressed into ultra-dense sheets, these silicon-nitride ceramic sheets resist deforming, expanding, or cracking when compressed, bent, or exposed to quick temperature changes. They’re just as strong and fracture resistant as zirconia ceramic, and hold their strength and shape at higher temperatures. All are stronger, harder, and more fracture resistant than most other ceramics.
Use these sheets for high-stress parts, such as engine parts. You can even use them as a substrate or insulator for electronic parts, such as computer chips. Since they stand up to temperature swings better than silicon carbide and mullite, they’re also good for use in furnaces and immersion heaters. Able to withstand wear, these sheets can be used to make cutting and roughing tools.
These sheets hold up to harsh chemicals, such as acids, but may corrode from nitric acid. They are not as corrosion resistant as silicon carbide.
