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 Sheets
- Color: Beige
- Maximum Temperature: 3,100° F
- Fabrication: Fired
- Dielectric Strength: 250V/mil
- Porosity: 13%
- Compressive Strength: 150,000psi
Often used as kiln shelves and refractory bricks, you can repeatedly move these mullite ceramic sheets between very hot and cold environments without deforming or cracking. All of these sheets are fully fired and seal out air and gas in high temperature applications, similar to nonporous alumina sheets. They also stand up to corrosion from chemicals, including acids that form while metal working. These sheets can even be used as electrical insulation.

Thermally Shock-Resistant Mullite Ceramic Powder
- Color: White
- Temperature Range: 0° F to 3,000° F
- Porosity: 6%
Mullite can withstand very high temperatures and will not deform or crack when repeatedly exposed to temperature fluctuations. Add it to slurries to create crucibles, ladles, and other parts by casting it. Mullite powder is common in furnaces, heaters, thermocouples, electrical insulation, and glass- and steel-industry refractories. When exposed to chemicals that are used to make steel, such as acid, it will not corrode. Due to fused fabrication, it has higher purity and more uniformity which leads to better thermal shock resistance and low thermal expansion.
Choose a particle size based on the application of your finished piece. Finer powders can be processed into finished pieces that will be harder, stronger, and more wear-resistant than those made with coarse grains. They may also have a finer finish. Parts made with coarse grain powders can be processed into pieces that are more porous and thermally shock-resistant than pieces made with finer grains. Mixing sizes can combine these properties.

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.
