Thermal Conductivity Of Ceramic Materials

Cordierite is a crystalline magnesium aluminosilicate.

Thermal conductivity of ceramic materials.

The thermal conductivity of ceramic materials plays an important role in its application. In a certain range increasing the thermal conductivity of ceramic materials by specific methods will improve its ability of heat conduction heat convection and heat radiation so as to further expand its application field. Steatite also known as soapstone or soaprock is a metamorphic rock a talc schist. Lasance articles design materials compounds adhesives substrates test measurement ceramics technical data thermal conductivity ceramics are increasingly used in packages and printed circuit boards because they have a number of advantages over plastics.

The most pure form ax05 has a thermal conductivity of up to 130 w mk. Large pieces of this material are available however it has poor mechanical properties and can be quite fragile. Twelve commercial ceramic materials were selected for this irradiation study and are listed in table 1 along with their room temperature physical properties. Shapal is a composite material made up of aluminum nitride and boron nitride and has a thermal conductivity of approximately 90 w mk.

Much higher thermal conductivity possible match. September 1 1999 clemens j. Of importance is that for some of the materials sic and al 2 o 3 different ceramic grades are used to obtain different non irradiated thermal conductivities for nominally equivalent base materials. Porcelain is a ceramic material made by heating selected and refined materials often including clay in the form of kaolinite to high temperatures.
