NOVELTY - High temperature-resistant heat conduction material comprises 0.11-0.13 wt.% carbon, 0.24-0.28 wt.% manganese, 0.62-0.66 wt.% silicon, 16-18 wt.% chromium, 6-8 wt.% nickel, 0.2-0.5 wt.% aluminum, 0.02-0.04 wt.% phosphorus, 0-0.03 wt.% sulfur, 0.2-0.5 wt.% rare earth oxide composition, 2.4-3.6 wt.% modified graphene oxide, and iron and unavoidable impurity (balance amount). USE - The heat conduction material is useful in incinerator combustion chamber (claimed). ADVANTAGE - The heat conduction material has thermal conductivity of 143-159 W/mK. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing high temperature-resistant heat conduction material, comprising (i) adding electrolytic copper, electrolytic nickel, industrial pure aluminum, industrial chromium oxide, crystalline silicon and iron nails into a melting furnace, heating and melting, cooling after completely melted to 1200 degrees C, then adding rare earth oxide composition and modified graphene oxide, and continuously melting for 30-60 minutes to obtain melting liquid, and (ii) adding smelted liquid into a casting ladle, allowing to stand for a moment, slagging off and casting at 170 degrees C to obtain heat conduction blank, then placing blank in a vacuum annealing furnace, then fast heating to 540 degrees C and reacting for 60 minutes, and then cooling to room temperature along with the furnace to obtain final product.
