The Description of alumina ceramic tube
Alumina (Al2O3) is the most commonly used industrial ceramic material due to its high mechanical strength, this high-performance. It results in suitable for use in many future-oriented processes. Additionally, the outstanding chemical resistance, great thermal properties and favorable cost of aluminum oxide (Al2O3 content > 90%), it makes alumina as a perfect material for many industries, from electrical applications and high-temperature applications.
Ceramic alumina tubes are found in a variety of electrical/electronic devices, engineering equipment that works as a structural ceramics, so these alumina ceramic tubes are with special shapes, such as flanged, stepped, slotted, multiple holes, half tube, threaded and so on. Sometimes, in order to enhance the breakdown insulation strength and mechanical strength, the cylindrical surface needs to be glazed.

Main characteristics of alumina ceramic tube
1. Extreme high-temperature stability under reducing, inert, and high-vacuum conditions under high temperature up to 1800°C.
2. Great mechanical properties, hardness, compressive and flexural strength are much higher stainless steel
3. Extreme wear and abrasion resistance., over 276 times in comparison with stainless steel
4. Extraordinary electrical insulation, it always us in many high voltage, high-current application
5. Chemical corrosion resistance under high temperature, even if with strong acid or alkali
6. Protective atmospheres or high vacuum at high-temperature to eliminate contamination or impurity.
7. Low material cost in high-level applications than other technical ceramics
