Aluminum Oxide Ceramic Thermal Conductivity

The thermal grease 860 is a silicone oil with a zinc oxide filler and 8616 and 8617 are synthetic oils with various fillers including aluminum oxide and boron nitride.

Aluminum oxide ceramic thermal conductivity. Other ceramics such as beryllium oxide and aluminum nitride feature a much higher conductivity but at a much higher price. Aluminum oxide al 2 o 3 ceramic properties. Ceramtec offers a wide range of material types with different property profiles that can be adjusted via a targeted matrix design. 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.

A relatively low cost is combined with a relatively high thermal conductivity especially when compared to fr4 board material. 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. Al 2 o 3 is an electrical insulator but has a relatively high thermal conductivity 30 wm 1 k 1 for a ceramic material. 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.

Non oxide ceramics aluminum nitride aln ceramic material with very high thermal conductivity aluminum nitride aln is a technical ceramic material that features an extremely interesting combination of very high thermal conductivity and excellent electrical insulation properties. However a word. Aluminium oxide al2o3 or alumina is one of the most versatile of refractory ceramic oxides and finds use in a wide range of applications. High strength and high hardness.

At 25 c the densities are 2 40 2 69 and 1 96 g ml for the greases 860 8616 and 8617 respectively. Aluminium oxide is insoluble in water. Alumina is one of the most cost effective and widely used material in the family of engineering ceramics. It can be produced through a variety of manufacturing methods but it is most commonly available in tape cast substrate form approximately 1mm thick.

Aluminium oxide is responsible for the resistance. Alumina or aluminum oxide al2o3 in its various levels of purity is used more often than any other advanced ceramic material. Alumina is the most well known fine ceramic material for chemical and physical stability. High heat resistance and high thermal conductivity.

Aln is a widely used ceramic in thermal management components with a thermal conductivity of approximately 180 w mk.
