lumina ceramic is the most mature of the engineering ceramics, offering excellent electrical insulation 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.
The alumina material is unique in that it does not expand, even at high temperatures. Components made of this material can withshand even the most abrupt temperature changes of several hundred degrees without damage.
These properties make aluminum titanate especially ideal for use in metallurgical melting, Components for furnaces, Thermocouple tubes, Machine components.
We manufactures various types of ceramic round insulator tubes, including single and multi-bore configurations, using Alumina, Mullite, Zirconia, and Sialon ceramic materials. We produce our tubes through extrusion, slip casting, and isostatic pressing.
Tubes:
Extruded Tubing
Cast Tubing (large diameter tubes)
Round Double Bore Tubing
Oval Double Bore Tubing
Round Four Bore Tubing
