Abstract. With the rapid development of modern industry and high-tech fields, there is an increasingly urgent demand for new materials with high temperature resistance, oxidation resistance, and corrosion resistance. Precious metals such as platinum (Pt), iridium (Ir), and rhodium (Rh) have high melting points (1772 °C, 1963 °C, 2447 ℃ respectively), strong corrosion resistance, thermal stability, and high temperature strength. They have been applied in traditional high-temperature materials such as crucibles for laser crystal melting and high-temperature gas measurement, etc. In addition, their applications in cutting-edge fields such as coating modification of aviation engines, nozzle materials for aerospace engines, and fuel cladding materials for satellite isotope batteries are also receiving increasing attention, The improvement of the performance of precious metal high-temperature materials and the innovation of research methods have become research hotspots in the scientific research field. This paper reviews the application requirements and application status of high temperature precious metal materials in aviation, aerospace and high-tech fields, introduces the research progress of our team in platinum-based superalloy materials, Platinum group precious metals high-throughput calculation, high-throughput experiment and database construction, and looks forward to the implications of genetic engineering of precious metal materials for the research and development of new high temperature precious metal materials. The further research direction and application prospect of high temperature precious metal materials are predicted and suggested.
