The mixture of natural Cooling water flow rate 10 lpm Processing time 2 and 4 min bauxite and zircon in the ratio of 7:3 by weight (based on compo Plasma temperature w2980 K sition of 3:2 mullite) was milled for 4 h with corundum ball mill Cooling time 10 min media using the Planetary Mill (Insmart, India).
thermal conductivity of polymer composites. Different research groups have developed different finite element models to investigate the effect of shape, size, orientation and type of filler on the thermal conductivity of polymer composites. Kumlutas and Tavman [12] investigated the effect of volume fraction of fillers on thermal conductivity
Thermal conductivity is a thermodynamic parameter playing an important role in the heat transfer process in geothermic and numerous engineering fields. In order to analyze the factors influencing the thermal conductivity of sandstone, the data of thermal conductivity obtained from the literatures in China and abroad were summarized.
