Ko nga ahuatanga matua o te whakamahana kauwhata:
1. ōritetanga o te hanganga whakawera.
2. pai te kawe hiko me te kawenga hiko teitei.
3. parenga waikura.
4. inoxidizability.
5. teitei matū matū.
6. kaha miihini teitei.
Ko te painga ko te kaha o te kaha, te utu nui me te iti o te tiaki. Ka taea e tatou te whakaputa anti-oxidation me te roa o te ora graphite crucible, graphite pokepokea me nga wahi katoa o te whakamahana kauwhata.
