Al2o3 Ceramic Structure

The most well known oxide ceramic material alumina or aluminum oxide al 2 o 3 in its various levels of purity is used more often than any other advanced ceramic material.

Al2o3 ceramic structure.

The most common form of crystalline aluminium oxide is known as corundum which is the thermodynamically stable form. Ullmann s encyclopedia of industrial chemistry. Although alumina denotes pure al2o3 the term is commonly applied to any ceramic whose major constituent is alumina even if the ceramic contains other components. The results showed that 3 vol zro2 al2o3 composite ceramics prepared by mechanical grinding and dispersing technology contained a large number of intragranular structures after microwave sintering at 1500 c for 30 min and its relative density flexural strength fracture toughness and vickers hardness were 99 07 520 21 mpa 7 64 mpa m1 2 and 18 79 gpa respectively.

Ceramtec offers a wide range of material types with different property profiles that can be adjusted via a targeted matrix design. The solid contents and temperature of the slurries were 45 vol and 50 c respectively. The top quality ai2o3 ceramic structure we make has myriad uses including heavy duty forming tools substrates heat sinks for lighting systems resistant cores in the electrical industry protection tubes in thermal processes tiles for wear protection and ballistics and catalyst carriers for the chemicals industry etc. The oxygen ions form a nearly hexagonal close packed structure with the aluminium ions filling two thirds of the octahedral interstices.
