High Purity Alumina Tube 99.6% Al2O3 Ceramic Tube High-Temperature
Applications
High Purity Alumina Tube, 99.6% Al2O3 Ceramic Tube
High purity alumina tubes can withstand very high temperatures
under reducing, inert or high vacuum conditions. They remain good
chemical resistance under high temperatures and have excellent wear
and abrasion resistance. 99.6% Alumina tube can withstand up to
1800℃.
Our high purity alumina (Al2O3 content > 99%) ceramics are
purpose-built to perform across a wide range of high-temperature
applications. Our high purity alumina shows considerable resistance
to chemical attack due to the lack of glassy phases that tend to
determine corrosion resistance.
Alumina tubes can be used in a multitude of applications include:
Turbine casting supports
Surgical devices
Knife sharpeners
Wafer processing components
Ceramic insulators
Vacuum devices
High-power resistor
Thermocouple components
Protection tubes
Igniter tubes
Thermostats

*Other sizes can be produced according to your requirement.
Note: Alumina products are sensitive to thermal shock. Try to warm
up the furnace chamber slowly. A heating rate between
150℃~300℃/hour is recommended for the first 1-1.5 hours so that the
alumina products can be evenly heated to reduce the impact of
thermal shock.
