Alumina Ceramic Hardness
Alpha phase alumina is the strongest and stiffest of the oxide ceramics.
Alumina ceramic hardness. Aluminium oxide is insoluble in water. In its most commonly occurring crystalline form called corundum or α aluminium oxide its hardness makes it suitable for use as an abrasive and as a component in cutting tools. Often hardness of ceramic material as with other materials is directly equated to wear resistance. Silicon carbide is more than four times harder than stainless steel.
Aluminium oxide al2o3 or alumina is one of the most versatile of refractory ceramic oxides and finds use in a wide range of applications. 40 hardness and fracture toughness of alumina ceramics tvrdoća i lomna žilavost aluminij oksidne keramike lidija ćurković vera rede krešimir grilec alen mulabdić faculty of mechanical engineering and naval architecture ivana lučića 1 zagreb croatia. Aluminium oxide is responsible for the resistance. Features of this material include.
Additionally it can be highly polished making it useful for precision sealing applications like pumps and pistons. It features high hardness and wear resistance low erosion levels high temperature resistance corrosion resistance and bioinertness. Alumina is an excellent high temperature ceramic material due to its high temperature stability. High strength and high hardness.
High purity alumina is usable in both oxidizing and reducing atmospheres to 1925 c. Pingxiang chemshun ceramics co ltd is a professional manufacturer of 92 95 alumina ceramics zta ceramics with the good character of strong hardness 9 mohs hardness scale strong abrasion resistance and impact corrosion resistance excellent heat resistance up to 1500centi degree and it s easy to install. The hardness of ceramic materials is a property which is of high significance as it relates to the ability of the material to withstand penetration of the surface through a combination of brittle fracture and plastic flow. Alumina is the most well known fine ceramic material for chemical and physical stability.
High electrical insulation high corrosion resistance and biocompatibility. High heat resistance and high thermal conductivity. Al 300 97 6 alumina this is a top quality alumina ceramic of 97 6 al 2 o 3 content widely used for high integrity components where its exceptional electrical and thermal properties are essential to operational stability and reliability. Its high hardness excellent dielectric properties refractoriness and good thermal properties make it the material of choice for a wide range of applications.
