Al2o3 Ceramic Thermal Conductivity

Aluminium oxide al2o3 or alumina is one of the most versatile of refractory ceramic oxides and finds use in a wide range of applications.

Al2o3 ceramic thermal conductivity.

Aluminium oxide is responsible for the resistance. Alumina is the most well known fine ceramic material for chemical and physical stability. Alumina oxide is chosen for its strength stiffness and resistance to corrosion as well as its electrical insulation and high thermal conductivity. 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.

Thermal conductivity 20 c. 8 0 x10 6 m m k upper continuous use temperature. Alumina ceramic is the material used in a wide variety of industrial and engineering applications for its high performance and purity. Its general properties are as follows.

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. High heat resistance and high thermal conductivity. 28 35 w m k thermal expansivity 20 1000 c. Alumina oxide is chosen for its strength stiffness and resistance to corrosion as well as its electrical insulation and high thermal conductivity.

Very high thermal conductivity measurements up to 22 600 w m 1 k 1 were reported by fenton e w rogers j s. Al 2 o 3 is an electrical insulator but has a relatively high thermal conductivity 30 wm 1 k 1 for a ceramic material. Al2o3 alumina ceramic top hat washer. Aluminium oxide is insoluble in water.

Alumina ceramic is the material used in a wide variety of industrial and engineering applications for its high performance and purity. Aluminoborosilicate abs glass ceramics containing 15 wt of multiwalled carbon nanotubes mwcnts exhibited an improvement of electrical conductivity by 10 6 and a thermal conductivity by 70. High electrical insulation high corrosion resistance and biocompatibility. The data is listed on pages 6 through 8 and graphed on page 1 where fenton and company are on curves 63.
