thermal conductivity bauxite

thermal diffusivity of the carbon composite with 10mm in diameter and 510mm in thickness. The thermal conductivity was calculated based on the one dimensional transient heat flow equation as following: K=α∙∙C p. Where α,, C p are the diffusivity (m2/s), density (g/cm3) and specific heat (J/(g∙K)) of the sample respectively.

 · Jordan Malaysia Sundar Calcined bauxite (including Rotary Kiln Bauxite and Round Kiln Bauxite) is produced by sintering/calcining of low iron, low alkali containing raw bauxites at temperatures of 1600 – 1800 degree Celsius. In this calcination process, the high refractory mineral phases corundum and mullite are formed.:::Jordan Calcined Bauxite is .
