Alumina Ceramic Thermal Conductivity

High heat resistance and high thermal conductivity.

Alumina ceramic thermal conductivity. Aln is a widely used ceramic in thermal management components with a thermal conductivity of approximately 180 w mk. Very high thermal conductivity measurements up to 22 600 w m 1 k 1 were reported by fenton e w rogers j s. High electrical insulation high corrosion resistance and biocompatibility. Ceramics with high or low thermal conductivity can be selected from our materials list.

Aluminium oxide al2o3 or alumina is one of the most versatile of refractory ceramic oxides and finds use in a wide range of applications. Aluminum oxide al 2 o 3 ceramic properties. Electrical insulator alumina is commonly used as a high temperature electrical insulator. It is ideal for wear resistant inserts or products.

In some journal of physics which has its name blurred up in reference 570 on page 1458 41 2026 33 1963. Silicon carbide sc1000 200. At present the thermal conductivity of the prepared beo ceramics can reach 280 w m k which is 10 times higher than that of aluminum oxide al2o3 ceramics. The data is listed on pages 6 through 8 and graphed on page 1 where fenton and company are on curves 63.

Aluminum nitride an216a 150. Aluminium oxide is insoluble in water. Aluminium oxide is responsible for the resistance. Thermal conductivity is a material property that describes ability to conduct heat thermal conductivity can be defined as the quantity of heat transmitted through a unit thickness of a material in a direction normal to a surface of unit area due to a unit temperature gradient under steady state conditions.

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. Information of silicon carbide. Abrasion resistant alumina is a very hard ceramic and is excellent at resisting abrasion. High strength and high hardness.

The raw materials from which this high performance technical grade ceramic is made are readily available and reasonably priced resulting in good value for the cost in fabricated alumina shapes. Al 2 o 3 is an electrical insulator but has a relatively high thermal conductivity 30 wm 1 k 1 for a ceramic material. It can be produced through a variety of manufacturing methods but it is most commonly available in tape cast substrate form approximately 1mm thick.
