We had the similar temperature challenge on gas turbines although magnitude of temperatures were couple of thousand K⁰ lower. We called those materials that can be commercially viable and withstand continues temperature of lets say 1800 K⁰ under thermal and pressure loads, "Unavailium"! Materials technology is by far the biggest barrier in front of disruptive breakthrough in almost any field!
