Sponge zirconium is a silver gray metal with a steel like appearance and a glossy finish. It is used in aerospace, nuclear reactions, and other industries.
Sponge zirconium has a melting point of 1852 ℃, a boiling point of 4377, and a density of 6.49. Zirconium easily absorbs hydrogen, nitrogen, and oxygen; Zirconium has a strong affinity for oxygen, and oxygen dissolved in zirconium at 1000 ℃ can significantly increase its volume. Zirconium is relatively stable in air; Powdered zirconium is easy to burn, and fine zirconium wires can be ignited with matches. At high temperatures, they can directly combine with dissolved oxygen, nitrogen, and hydrogen.
