Cobalt – Crystal Structure - Periodic Table of Elements
WEBNov 13, 2020 · A possible crystal structure of Cobalt is hexagonal close-packed structure. In metals, and in many other solids, the atoms are arranged in regular arrays called crystals. A crystal lattice is a repeating pattern of mathematical points that extends throughout space.
Cobalt - Wikipedia
WEBCobalt is a chemical element; it has symbol Co and atomic number 27. As with nickel, cobalt is found in the Earth's crust only in a chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, somewhat brittle, gray metal.
The Coy Element Cobalt | Periodic Table - ChemTalk
WEBThe beta form, or β-form, of cobalt assumes a closely-packed, hexagonal, crystalline structure. The alpha form, or α-form, exists as a cubic crystal. Although both allotropes are stable under normal conditions, the beta form dominates under temperatures of approximately 400°C, or 750°F.

WEBAug 31, 2024 · cobalt (Co), chemical element, ferromagnetic metal of Group 9 (VIIIb) of the periodic table, used especially for heat -resistant and magnetic alloys. The metal was isolated (c. 1735) by Swedish chemist Georg Brandt, though cobalt compounds had been used for centuries to impart a blue colour to glazes and ceramics.
