The main use of zirconia is in the production of hard ceramics, such as in dentistry, with other uses including as a protective coating on particles of titanium dioxide pigments, as a refractory material, in insulation, abrasives, and enamels.

Zirconium dioxide or zirconia is one of the most widely used ceramic oxides. Its applications range from use in abrasive products, dental bridges and crowns, additive in paints and lacquers, in fuel cell membranes and in joint implants

Zirconia is even more durable than the conventionally used PFM ceramics. For instance, solid zirconia contains more stabilizers than PFM ceramics, making it more durable to withstand forceful chewing and grinding. If properly maintained, zirconia restorations can last a patient's lifetime.
