IPC: C04B33/32
Filed: 1997-03-11
Abstract: PROBLEM TO BE SOLVED: To improve strength and fracture toughness by producing a graphite refractory material of a composite material which contains a graphite source material, SiC, SiO2 , BN and carbon fiber in specified proportions. SOLUTION: The graphite refractory material contains 5 to 30wt.% graphite source material, a ceramic component having <2μm particle size including 10 to 70wt.% SiC, 1 to 30wt.% SiO2 and 1 to 5wt.% BN, and 0.1 to 2wt.% carbon fiber.
