    Thermal-Shock-Resistant Mullite Ceramic Tubes

    Image of Product. Front orientation. Ceramic. Thermal-Shock-Resistant Mullite Ceramic Tubes.
    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.

    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 alloy. Similar to nonporous alumina, these tubes help seal out gas and liquids.
