Highlights

  • Increase in operating temperatures of the gas turbine engine hot path demands application of more high-temperature materials for the GTE metal elements production

  • Nowadays the greatest distribution was gained by the crucibles of mullite-corundum and corundum-zirconiumoxide-silicate structures differing in high thermal stability due to formation of microcracking structure

  • The presence of silicon at the ceramic structure leads to the increased erosion of refractory material and the pollution of metal by silicon
