In contrast, -MoC and -MoC are high-temperature phases which become stable at temperatures above about 1700C. The -MoC phase is considered to be a metastable phase at all compositions and temperatures and is therefore not found in the phase diagram.
Ngunit MOC - MoC at mataas na temperatura phase nagpapatatag sa mga temperatura sa itaas 1700C. Phase-moc itinuturing na isang metastable phase para sa lahat ng komposisyon at mga temperatura at samakatuwid ay hindi sa bahaging diagram.
