abstract = "Dense aluminum nitridesilicon carbide (AlNSiC) solid solutions with a 2H structure were fabricated by the post-heat treatment of dense AlNSiC composites fabricated by spark plasma sintering (SPS). The changes in the relative density, microstructure, and phases present were investigated for the compositions of 25 mol% AlN75 mol% SiC (AlN 25), 50 mol% AlN50 mol% SiC (AlN 50), and 75 mol% AlN25 mol% SiC (AlN 75). The AlNSiC composites fabricated by the SPS were dense ceramics with fine microstructures and composed of 2H and 6H AlNSiC solid solutions. The AlN 50 samples heat treated at 2200\textdegreeC and the AlN 75 samples heat treated at 2100\textdegreeC were also dense ceramics and composed of only the 2H AlNSiC solid solution. In contrast, the AlN 25 samples heat treated at 2200\textdegreeC were porous ceramics and composed of several AlNSiC solid solutions (2H, 4H, 6H, and 15R), and the AlN 75 samples heat treated at 2200\textdegreeC were decomposed into an Al melt. Dense AlNSiC solid solutions composed of only the 2H phase can be obtained by controlling the heat-treatment temperatures, except for the AlN 25 sample.",
