Taupānga

Ko te Hafnium diboride he karaehe whiti-pango-hina-pango, no te punaha hexagonal te hanganga karaihe. Ka rite ki te rauemi uku teitei ultra-teitei, hafnium diboride (HfB2) he ira whakarewa tiketike (3380 ℃), he maha whakamahia te reira i roto i te rauemi anti-ablation i roto i te taiao hāora teitei-te pāmahana me te āhuatanga o te pakeke tiketike, modulus tiketike, teitei kawe waiariki me te kawe teitei. Kei te whakamahia nuitia i roto i nga paninga kakahu-aukati, nga rauemi whakaahuru, taputapu tapahi me nga punaha tiaki waiariki aerospace me etahi atu mara.
