Alumina ceramic tube has the characteristics of high hardness, high strength, high temperature oxidation resistance, good corrosion resistance, and excellent insulation performance. In addition, the alumina ceramic tube also has good wear resistance, stability and chemical corrosion resistance, and can maintain the performance of the material in extreme environments.


Alumina ceramic tube has the following main properties:


  1. High hardness: The molar hardness of alumina ceramic tube is as high as 9, second only to diamond and boron carbide, so it has good wear resistance.

  2. High strength: Alumina ceramic tube has good mechanical strength and toughness, and its tensile, compressive, bending and impact resistance are excellent, making it very suitable for use in harsh environments.

  3. High-temperature oxidation resistance: Alumina ceramic tubes can work for a long time in high-temperature environments because they are not easily oxidized and brittle at high temperatures.

  4. Corrosion resistance: Alumina ceramic tubes are resistant to corrosion by various acids, alkalis, salts and other chemical media, especially in high temperature and high pressure environments.

  5. Excellent insulation performance: Alumina ceramic tubes have excellent insulation performance and can maintain stable insulation performance under high voltage and high frequency conditions.

  6. Good chemical stability: Alumina ceramic tubes have good chemical stability and are not easily corroded and damaged by acids, alkalis and other chemical substances.


In summary, alumina ceramic tubes have the characteristics of high hardness, high strength, high temperature oxidation resistance, corrosion resistance, excellent insulation performance and good chemical stability, so they can be used in various high temperature, high pressure, strong corrosion and wear environments widely used.


Alumina ceramic tubes are usually used in electronic, mechanical and chemical equipment under high temperature, high pressure and strong corrosion environment. For example, in petroleum, chemical industry, metallurgy, electric power and other fields, alumina ceramic tubes are widely used in pipeline isolation, reactor lining, heater, catalyst carrier and so on. In addition, it is also widely used in the fields of semiconductor devices, optical fiber communication and medical equipment manufacturing.
