E toru ngā momo matua o te polymorph silicon carbide
E 250 pea ngā momo tioata o te karawiti hiko. Nā te mea he raupapa momo rite tonu te karawiti hiko me te hanganga tioata rite, ko ngā āhuatanga o te karawiti hiko he rite tonu ki te tioata maha.
He tino onge te karāhe hāora (Mosanite) i runga i te Ao, engari he mea noa i te wāhi. Ko te karāhe hāora he wāhanga noa o te puehu wāhi huri noa i ngā whetū waro. Ko te karāhe hāora e kitea ana i te wāhi me ngā rangitoto he tioata āhua-β tonu.
Ko te A-sic te mea tino kitea o ēnei momo maha. Ka hangaia i ngā pāmahana neke atu i te 1700°C, ā, he hanganga tioata hexagonal tōna, he rite ki te wurtzite.
Ko te B-sic, he rite ki te taimana te hanganga tioata sphalerite, ka hangaia i raro i te 1700°C.
