2018-5-17  Thermal conductivity was increased with bauxite additives increases, because the porosity decreases due to glass phase increasing from fluxing oxides, which melt at temperatures below 1200 °C. As well as the main effect of porosity is to reduce thermal conductivity, because porosity acts as a

2018-4-21  The thermal conductivity was decreased with porosity increases from 0.5 to 0.4 W/m K for bauxite additions and to 0.36 W/m K for metakaolin additions. The effect of porosity is important; when the thermal conductivity of the air is negligible compared to the solid phases, the addition of large volume fractions of pores can dramatically reduce ...

Alumina Al2O3 - PubChem

Bauxite is a naturally occurring, heterogeneous material composed primarily of one or more aluminum hydroxide minerals, plus various mixtures of silica, iron oxide, titania, aluminosilicate, and other impurities in minor or trace amounts. The principal aluminum hydroxide minerals found in varying proportions with bauxites are gibbsite and the polymorphs boehmite and diaspore.
