[0057] figure 1 It is a schematic cross-sectional view showing the joined body of the metal material and the ceramic-carbon composite material according to the first embodiment.
[0058] like figure 1 As shown, the joined body 6 of the metal material and the ceramic-carbon composite material is a joined body of the metal material 4 made of metal and the ceramic-carbon composite material 1 .
[0059] (Metal material 4)
[0060] The metal constituting the metal material 4 is not particularly limited. Specific examples of metals include W, Mo, Ti, Si, Al, Cr, Cu, Sn, alloys thereof, and the like. The metal material 4 preferably includes at least one of W and Mo. That is, the metal material 4 is preferably composed of W, Mo, or an alloy of W and Mo.
[0061] The metallic material 4 may have any shape. The shape of the metal material 4 may be, for example, a granular shape, a plate shape, a columnar shape, a fiber shape, or the like. The metal material 4 is preferably powd...
experiment example 1
[0090] As described below, a ceramic-carbon composite material having substantially the same structure as the ceramic-carbon composite material 1 was produced.
[0091] As the carbon particles 2, graphite (mesophase small spheres, manufactured by Toyo Tanso Co., Ltd.) was used. As the ceramic, aluminum nitride powder (H type manufactured by Tokuyama Co., Ltd.) was used.
[0092] Graphite (10g), aluminum nitride (3.54g) and Y as sintering aid 2 O 3(0.19g) mixed to obtain a mixed powder, and the obtained mixed powder was mixed with acrylamide (8g) and N,N'-methylenebisacrylamide (1g) dissolved in isopropanol (45g) by a gel casting method. ) in a binder solution (2.49 g), and the mixture was cast in a plastic mold. The volume ratio of graphite to ceramic in the mixture was 80:20. The obtained mixture was dried under normal pressure at 80° C. for 12 hours to obtain a dried product. Next, the dried product was heated in a vacuum at 700° C. for 1 hour to remove acrylamide as a ...
experiment example 2
[0101] A silicon carbide-graphite composite material was obtained in the same manner as in Experimental Example 1, except that silicon carbide (E10 type manufactured by Ube Industries, Ltd.) was used instead of aluminum nitride. The volume ratio of graphite to ceramic is 70:30.
[0102] By the method described in Example 1, the bulk density, bending strength and thermal conductivity of the obtained silicon carbide-graphite composite material were measured. The results are shown in Table 1 below.
