Product Overview
Alumina Ceramic tubes
1.Aluminum oxide ceramic tube is the most mature of the engineering ceramics, offering excellent electrical insulat Good insulator/alumina tube furnace for metallurgical melting/innovacera ion properties together with high hardness and good wear resistance but relatively low strength and fracture toughness.Alumina has a high melting point, high hardness,although mechanical strength is reduced at temperatures above 1000 C. Due to the relatively large coefficient of thermal expansion, thermal shock resistance is reduced.Good chemical stability of alumina leads to
high corrosion resistance. It is insoluble in water and only slightly soluble in strong acid and alkaline solutions. Testing has shown that the low chemical solubility of alumina ceramics components makes them highly resistant to chemical corrosion. This is what makes high purity alumina the material of choice for components in a wide range of industrial applications.

-- Ceramic tubes are used when conditions exclude the use of metal, either for chemical reasons or because of excessive
temperatures.Their main applications are between 1000 and 1800°C.
-- Ceramic tubes should be mounted in a hanging position above 1200°C to prevent distortion or fracture due to bending stresses.
