%X 高温合金因其高温下具有优异的力学性能、良好的抗氧化和耐腐蚀性能，在国民经济和现代国防建设领域都有着广泛的应用。真空感应熔炼是高温合金生产的重要工艺，在高温低压长时间服役过程中，坩埚耐火材料的分解、溶解以及与高温合金中活性元素的化学反应都将影响高温合金的纯净度，进而影响合金性能。因此，制备高热力学稳定性和耐高温熔体侵蚀性能优异的坩埚耐火材料，是实现高纯高温合金熔炼的关键。为此，本文就高温合金感应熔炼坩埚用耐火材料的发展、材料的热力学稳定性，以及耐火材料与高温合金熔体间相互作用展开综述，并就高稳定性耐火材料在高温合金熔炼方面所存在的问题及其未来发展方向提出建议。<br />
Superalloys are widely used in the na-tional economy and modern national defense construction considering their excellent mechanical properties, good oxidation resistance and corrosion resistance at high temperatures. Vacuum in-duction melting is an important process in the production of superalloys, the decomposition and dissolution of crucible refractories and the chemical reaction with active elements in molten super-alloys during long-term service at a high temperature and low pressure will affect the purity of the superalloys, which in turn will affect the properties of the superalloys. Therefore, the preparation of crucibles with high thermal stability and excellent corrosion resistance to molten alloy is the key to achieving high purity of superalloys. In this paper, the development of refractories for induction melting crucibles of superalloys, the thermal stability of materials, and the interfacial reaction be-tween refractories and molten superalloys are reviewed, the problems in the application of high thermal stability refractories in superalloys are discussed and the future development of refracto-ries for superalloys induction melting is suggested.
