Steatite also known as soapstone or soaprock is a metamorphic rock a talc schist.
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.
The r conductivity is the thermal conductivity radial to the annual rings t is tangential to those rings and u is unspecified.
Note that the wide variation in the values.
Aluminum nitride has a very high thermal conductivity while being an electrical insulator.

The property that measures how well heat is transmitted through a material is called thermal conductivity.
Cordierite is a crystalline magnesium aluminosilicate.
Most frequently found htcc base high thermal conductivity ceramics are alumina and nitride ceramics such as aln bn and si 3 n 4 materials.
The thermal conductivity of a material is a measure of its ability to conduct heat it is commonly denoted by or.
Among fine ceramics also known as advanced ceramics some materials possess high levels of conductivity and transfer heat well while others possess low levels of conductivity and transfer less heat.
In summary the published thermal conductivity values of ceramics are ideally suited to match experimental results to numerical simulations and i am afraid that this is exactly what.
The table shows the range of values at room temperature for a number of frequently used ceramics from various sources.
Longitudinal heat flow tprc 1 page 24a.
A theoretical analysis of the thermal conductivity κ v of metals and ceramics from their young s modulus e atomic weight m and density ρ based on a harmonic oscillator model is presented the κ v value is expressed as a g n 0 3 ρ e m 3 2 2 where a is the maximum displacement of a harmonic oscillator and equals the mean free path of lattice vibration g is the size factor.
