Description
Zirconia powder serves as the foundational substance for crafting specialized zirconia ceramics, advanced refractories, optical communication equipment, and new energy materials. Serving as a crucial ingredient in cutting-edge technological materials, the utilization of high-purity ultrafine composite zirconia powder continues to broaden. This powder showcases attributes like low-temperature sintering, resulting in zirconium components that exhibit remarkable hardness, impressive strength, and a pristine whiteness.
