Ko te whakaeke i te rino konumohe konutai
Ko te konumohe kromo rino (Fecral) he taonga tuuturu e whakamahia nuitia ana i roto i nga tono me nga momo whakahaere hiko tae noa ki te 1,400 ° C (2,550 ° F).
E mohiotia ana nga kaikorero mo te papaa teitei, me te kaha o te kaha me nga waahanga iti ake i nga waahanga ka taea te whakamaori ki nga mea iti ake i te tono me te penapena iti. Ko te tino nui o te pāmahana whakahaere nui ka taea hoki te arahi i te ora roa ake. Ko te konumohe konutai rino te hanga i te konumohe konumohe hina (al2o3) i runga i te 1,000 ° C (1,832 ° F) e kaha ana ki te aukati i te aukati. Ko te hanganga o te oxide e kiia ana ko te whakakotahi i a ia ano me te tiaki i nga waahanga poto i te waa o te whakarewa ki te whakapiri whakarewa. Ko te konumohe konumohe rino he iti te kaha miihini ki te whakataurite ki nga taonga Chrome nika tae atu ki te kaha Creep.
