Alumina Ceramic Insulator Ring/Innovacera

Material Description

Alumina (aluminum oxide) is the most important, widely used and cost effective oxide ceramic material. The technical alumina ceramics contain at least 80% of aluminum oxide (AL2O3). Small amounts of silica (SiO2), magnesia (MgO) and zirconia (ZrO2) may be added to alumina ceramics. Addition of zirconia to alumina ceramic results in considerable increase of the material fracture toughness.

Application of Al2O3: 
Aluminum ceramics are widely used in electronics and electrical engineering, metallurgical processes, chemical technologies, medical technologies, mechanical engineering, military equipment. 
Aluminum ceramics are used for manufacturing insulators, capacitors, resistors, furnace tubes, sealing refractory parts, foundry shapes, wear pads, thermocouple protection tubes, cutting tools and polishing/grinding powders, ballistic armor, laboratory equipment, bio-ceramic parts for orthopedic and dental surgery, bearings.   

Features

 Typical Alumina characteristics include: 
-High mechanical strength (flexural strength) and hardness; 
-High wear resistance; 
-High resistance to chemical attacks of strong acids and alkali even at high temperatures; 
-High stiffness; 
-Excellent insulating properties; 
-Low coefficient of thermal expansion; 
-Good fracture toughness; 
-Good thermal conductivity; 
-Good biocompatibility.
