Keywords: alumina ceramics, ceramic ring, alumina ring, ceramic insulator ring, ceramic ring, ceramic insulator
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 is an electrically insulating material, with a high electrical resistivity, increasing with purity.
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.
