Local:
Zirconium forms a number of compounds as below:

• Zirconia (also known as zirconium oxide or as zirconic anhydride, ZrO2 ): toxic, heavy white powder that is insoluble in water, soluble in mineral acids; melts at 2700°C; used in ceramic glazes, special glasses, as an abrasive, a refractory material, and a component of acid- and alkali-resistant glasses and of ceramics employed in fuel cells and medicine, and to make piezoelectric crystals.
• Zirconium Acetate (ZrC₂H₄O₂, CAS RN: 7585-20-8) used as a flame retardants for textiles.
• Zirconium Neodecanoate (ZrC₄₀H₇₆O₈, CAS RN: 39049-04-2)
• Zirconium Acetylacetonate ((C₅H₇O₂)₄Zr, CAS RN: 17501-44-9)
• Zirconium Boride (ZrB₂, CAS RN: 12045-64-6): toxic, gray, hard powder; melting at 3000°C; used as an aerospace refractory, in cutting tools, and to protect thermocouple tubes.
• Zirconium Butoxide (C₁₆H₃₆O₄, CAS RN: 1071-76-7)
• Zirconium Carbide (ZrC, CAS RN: 12070-14-3): Hard, gray crystals or powder; soluble in water and acids; ignites spontaneously in air; melting at 3400°C, boiling at 5100°C; used as an abrasive, refractory, and metal cladding, and in cermets, incandescent filaments, and cutting tools.
• Zirconium Carbonate (CAS RN: 12671-00-0): white powder used as in manufacturing of zirconium compounds, manufacturing paint drier auxiliaries, pigments, various catalysts and paper sizings.
• Zirconium Dicarbide (ZrC₂, CAS RN: 12340-54-4)
• Zirconium Fluoride (ZrF₄, CAS RN: 7783-64-4, 13569-28-3, 13814-22-7, 13842-94-9)
• Zirconium Hydride (ZrH₂, CAS RN: 7704-99-6, 13940-37-9): flammable, gray-black powder; used in powder metallurgy and nuclear moderators, and as a reducing agent, vacuum-tube getter, and metal-foaming agent.
• Zirconium Hydroxide (Zr(OH)₄ CAS RN:12688-15-2, 14475-63-9): toxic, amorphous white powder; insoluble in water, soluble in dilute mineral acids; decomposes at 550°C; used in pigments, glass, and dyes, and in making other zirconium compounds.
• Zirconium Iodide (ZrI₂, CAS RN: 14728-76-8, 13779-87-8, 15513-85-6)
• Zirconium Nitrate (CAS RN: 12372-57-5)
• Zirconium Nitride (ZrN, CAS RN: 25658-42-8): hard, brassy powder that is soluble in concentrated acids; melts at 2930°C; used in refractories, cermets, and laboratory crucibles.
• Zirconium Oxychloride (ZrOCl₂, CAS RN: 7699-43-6): White crystals that are soluble in water, insoluble in organic solvents, and acidic in aqueous solution; used for the manufacture of other zirconium salts, textile dyeing, oil-field acidizing, in cosmetics and greases, and for antiperspirants and water repellents and TIO₂ pigment coating.
• Zirconium Oxynitrate (ZrO(NO₃)₂, CAS RN:13826-66-9)
• Zirconium Phosphate (ZrO(H₂PO₄)₂): toxic, dense white powder insoluble in water, soluble in acids and organic solvents; decomposes on heating; used as an analytical reagent, coagulant, and radioactive-phosphor carrier.
• Zirconium Silicate (ZrO₄Si, CAS RN: 10101-52-7)
• Zirconium silicide (CAS RN: 12039-90-6)
• Zirconium sulfide (CAS RN: 12039-15-5)
• Zirconium Tetrachloride (ZrCl₄, CAS RN: 10026-11-6): toxic, white lustrous monoclinic crystals; decomposes in water, soluble in alcohol, sublimes above 300°C; used to make pure zirconium and for water-repellent textiles.
• Zirconium-95: radioactive isotope of zirconium (Half-life of 63 days with beta and gamma radiation); used as a catalyst in a cracking plant and to trace petroleum circulation flows.
• Zirkelite  A black mineral consisting of an oxide of zirconium, titanium, calcium, ferrous iron, thorium, uranium, and rare earths.
• Calcium Zirconate (CaZrO₃ CAS RN: 12013-47-7)
