Monoclinic Zirconia
CAS-номер: 1314-23-4
Unstabilized monoclinic zirconia powder with ZrO₂+HfO₂ ≥99%. Used in refractory, foundry, and high-temperature applications where phase-transformation toughening is not required. High melting point (~2715°C), excellent corrosion resistance, and low thermal conductivity make it a key raw material for advanced refractories and investment casting.
