At high temperature, which outcome occurs because silicon carbide (SiC) crucibles degrade?

💡 Explanation

The primary degradation mechanism is sublimation of SiC; rather than forming a strong protective layer. Sublimation causes direct material loss because vapor pressure increases the removal rate, therefore weakening the crucible, rather than oxidation.
