CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Zirconium powder wet appears as a gray amorphous sludge with not less than 25% water. |
|---|---|
| Color/Form | Bluish-black, amorphous powder or grayish-white lustrous metal (platelets or flakes) of hexagonal lattice below 865 °C; body-centered cubic above 865 °C |
| Boiling Point | 6471 °F at 760 mmHg (NIOSH, 2023) |
| Melting Point | 3375 °F (NIOSH, 2023) |
| Solubility | Insoluble (NIOSH, 2023) |
| Density | 6.51 (Metal) (NIOSH, 2023) - Denser than water; will sink |
| Vapor Pressure | 0 mmHg (approx) (NIOSH, 2023) |
| Stability/Shelf Life | Stable under recommended storage conditions. |
| Autoignition Temperature | Cloud ignition temperature: 330 °C |
| Corrosivity | Zirconium is a very reactive metal that, in air or aqueous solution, immediately develops a surface oxide film. This stable, adherent film is the basis for zirconium's corrosion resistance. |
| Other Experimental Properties | Atomic number 40; valance 3 and 4. ... Brinell hardness: 85. Can absorb up to 10 atoms percent of oxygen or nitrogen; reacts with hydrofluoric acid, aqua regia, hot phosphoric acid; not attacked by cold, very slightly attack by hot concentrated sulfuric or hydrochloric acid; not attacked by nitric acid. On prolonged heating the compact form combines with oxygen, nitrogen, carbon, and the halogens. |
| Chemical Classes | Metals -> Metals, Inorganic Compounds |
