Good chemical resist/ceramic alumina tubes for high
temperature application/innovacera
Keywords: alumina ceramics, ceramic tube, alumina tube, ceramic insulator tube, ceramic thermocouple protection tubes,
high temperature tube, ceramic thermocouple.
1. Introduction:
Alumina 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 ***0 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.
