Fe-Sialon-corundum composite refractory material and preparation method thereof
The invention discloses a Fe-Sialon-corundum composite refractory material having low production cost, good toughness and containing metal-plastic phases and a preparation method thereof. The Fe-Sialon-corundum composite refractory material comprises the following original materials: corundum aggregate and fine powder, Al2O3 micropowder, SiC fine powder, Si powder, silicon-iron alloy powder and metal Al powder; Fe-Sialon-corundum composite refractory material is formed by adopting vibratory pressurization and prepared by a machine-pressing method for forming and sintering by in-situ nitriding reaction under the N2 atmosphere or the carbon-immersing condition. The Fe-Sialon-corundum composite refractory material disclosed by the invention has the advantages that the Fe-Sialon-corundum composite refractory material having good thermal-shock stability, good toughness, low production cost and containing metal-plastic phases is prepared by introduction of a certain amount of silicon-iron alloy powder, optimized combination of the material and reasonable granularity ratio and adoption of in-situ nitriding reaction.
