Applications of Alumina Ceramic tubes:

Thermal Processing: Used as furnace tubes, radiant tubes, and kiln furniture for heat treatment, sintering, and brazing.
Temperature Measurement: Serving as protective sheaths for thermocouples and thermistors in corrosive and high-temperature environments.
Electrical & Electronics: Acting as insulating beads, spacers, and housings in electrical systems and electronic heaters.
Semiconductor Industry: Used as process tubes in diffusion furnaces for wafer manufacturing due to their high purity and temperature resistance.
Industrial Equipment: Employed as guide tubes, wear-resistant liners, and components in chemical processing and metallurgy.
