Thermal conductivity in hot-pressed silicon carbide ...
1996-1-1 · Abstract. Silicon carbide ceramics with equiaxed grain structure were obtained by hot-pressing at 2000 °C in a vacuum with the aid of sufficient amounts of Al 2 O 3 and Y 2 O 3 as sintering additives. The thermal conductivity of the SiC ceramics was investigated using a laser-flash technique and a pure polycrystalline 6H-SiC prepared by Lely's ...
