As fracture resistant and durable as metal, this temperature-resistant zirconia ceramic has been fired to obtain a high hardness and can be used in high-wear applications.

Protectively sheath materials, such as thermocouples, that move between hot and cold environments. Similar to nonporous alumina tubes, air and gas cannot pass through these mullite tubes.

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.
