Zirconium dioxide ceramics
Zirconium dioxide (ZrO2) has an exceptional range of properties, such as:
All these combinations make zirconia-based ceramics indispensable for a wide variety of industries (from the production of refractories to medicine).
Zirconium dioxide is used in the production of highly refractory products, heat-resistant enamels, refractory glasses, various types of ceramics, ceramic pigments, solid electrolytes, thermal protective coatings, catalysts, cutting tools and abrasive materials. In recent years, zirconia has become widely used in fiber optics and the manufacture of ceramics used in electronics.
