Uses Zirconium oxide occurs in nature as the mineral baddeleyite. The oxide has many industrial applications. It is used as a refractory material. It is used in making highly reflective glazes for ceramics, glasses, linings of metallurgical furnaces, crucibles, and laboratory equipment. The oxide is used to produce oxyhydrogen and incandescent lights. Other uses are in producing piezoelectric crystals, heat-resistant fibers, and high-frequency induction coils. The hydrous oxide is used in treating dermatitis resulting from poison ivy.
Uses Instead of lime for the oxyhydrogen light; with earths of the yttrium group in incandescent lighting (Nernst lamps); as pigment, abrasive; manufacture of enamels, white glass, refractory crucibles, and furnace linings.
