Zirconium oxide is widely used in watches, cutlery, heart pacemakers, scissors, and golf clubs. Zirconia is unique since it is a tough ceramic, with a combination of hardness, strength, fracture toughness, wear resistance, and chemical inertness. Stabilizers such as yttria are added to control the microstructure and for toughening.
Zirconium oxide ceramics can thus be used to make refractory crucibles, channels, filters, coatings and the like. These ceramic crucibles (Fig. 17.3) have high chemical resistance and, because of the high melting temperature of the zirconium oxide, allow continuous exposure to temperatures in excess of 2000 °C. On the other hand, due …
German chemist Martin Heinrich Klaproth accidentally discovered zirconium dioxide (ZrO2) in 1789. It was later isolated by the Swedish chemist Jöns Jakob Berzelius in 1824. ZrO2 is a white crystalline …
