Thermally Shock-Resistant Mullite Ceramic Tubes
- Color: Beige
- Maximum Temperature: 3,000° F
- Fabrication: Fired
- Porosity: 0%
- Compressive Strength: 79,000 psi
These mullite tubes can repeatedly be exposed to temperature fluctuations without deforming or cracking. They can be used as a protective cover over materials that are moved between hot and cold environments, such as thermocouples. These tubes are fully fired and seal out air and gas in high temperature applications like nonporous alumina. They also resist corrosion from a variety of chemicals. Use them in furnaces, heaters, electrical insulation, and glass- and steel-industry refractories.

Thermally Shock-Resistant Mullite Ceramic Rods
- Color: Beige
- Maximum Temperature: 3,100° F
- Fabrication: Fired
- Porosity: 13%
- Compressive Strength: 150,000 psi
Used in prototypes, insulators, and machine tooling, these mullite ceramic rods won’t deform or crack when exposed to extreme temperature changes, high heat, or stress. Fully fired, they seal out air and gas in high temperature applications, similar to nonporous alumina sheets. These rods won’t corrode from chemicals, including acids that form while metal working.

High-Strength Fracture- and Wear-Resistant Zirconia Ceramic Rods and Discs
Ideal for applications that must resist bending and wear as well as carry heavy loads, these rods and discs are often used for sleeve bearings and shafts instead of metal. Added yttria gives this material more strength and lowers the chances of cracking from impact compared to standard zirconia, alumina, and silicon nitride ceramic. If cracks do occur, they will not spread, extending the life and reliability of this material. It also means this zirconia blend resists wearing down from rubbing against another part or abrasion from chemical slurries.
Zirconia ceramic resists bending better than alumina and silicon nitride ceramic but does not withstand rapid temperature changes or high temperatures as well as other high-performance ceramics.

Extra Thermally Shock-Resistant Single-Closed-End SiAlON Ceramic Tubes
- Color: Gray
- Maximum Temperature: 1,830° F
- Fabrication: Fired
- Porosity: 0%
- Compressive Strength: 510,000 psi
Often used as a protective shield in thermocouples and other conditions with drastic climate changes, these SiAlON ceramic tubes won't deform, expand, or crack when repeatedly exposed to large temperature changes. Submerge the closed end of the tube into harsh settings, such as tanks and furnaces, to protect contents from coming into contact with harmful liquids and gases.
These tubes are stronger and resist thermal shock better than mullite and alumina, though they don’t remain as stable in ultra-high temperatures. They're not as hard as silicon carbide, so they shouldn't be used when wear resistance is necessary. Because they hold up to chemicals, they’re good for use with molten metal, such as aluminum and zinc. Similar to nonporous alumina, these tubes help seal out gas and liquids.
