Ceramic Thermal Conductivity Cryogenic
Not all properties are available for all materials.
Ceramic thermal conductivity cryogenic. The materials currently in the database are ones commonly used in the construction of cryogenic hardware. The properties available include thermal conductivity specific heat linear thermal expansion thermal expansion coefficient and young s modulus. Since ceramic materials have good mechanical properties and favorable thermal properties low thermal conductivity and thermal expansion they can be used as adequate materials in cryogenic engineering. Ceramics especially zirconia based ceramics have been an attractive candidate for fundamental research at cryogenic temperatures due to their favorable mechanical properties corrosion resistance.
Looking at the values quoted in various handbooks papers and data sheets two things are observed. Abstract the thermal conductivity and specific heat of a commercial machinable ceramic have been measured to 0 06 k. The role of impurities and of crystallites is discussed. The data are compared with those of other materials commonly used in the construction of cryogenic apparatus.
The lower this value for a material is the lower its thermal conductivity and the better it is at avoiding thermal bridges.
