Explanation
ceramics with ZrO2 as the main component Zirconia has three crystal forms: monoclinic phase, tetragonal phase and cubic phase. The transformation of monoclinic phase to tetragonal phase is accompanied by a volume change of 7% -9% when heating at about llOO ℃, and the transformation of monoclinic to tetragonal phase will occur in the opposite direction when cooling at about 1000 ℃, which also produces a large volume change, which is easy to cause product cracking.
