Crystal structure hexagonal close ... Cobalt is a chemical element; it has symbol Co and atomic number 27. As with nickel, cobalt is found in the Earth's crust only ...
FCC crystal structure is commonly found in cobalt rich alloys, while chromium rich alloys tend to have BCC crystal structure. The γ phase Co-Cr alloy can be converted into the ε phase at high pressures, which shows a HCP crystal structure.
Cobalt(II) oxide is an inorganic compound that has been described as an olive-green [3] or gray [4] solid. It is used extensively in the ceramics industry as an additive to create blue-colored glazes and enamels , as well as in the chemical industry for producing cobalt(II) salts.
The crystal structure of the skutterudite mineral was determined in 1928 by Oftedahl [7] [8] to be cubic, belonging to space group Im-3 (number 204). The unit cell can be considered to consist of eight smaller cubes made up of the Co atoms. Six of these cubes are filled with (almost) square planar rings of As, each of which is oriented parallel ...
Cobalt(II,III) oxide is an inorganic compound with the formula Co 3 O 4. It is one of two well characterized cobalt oxides. It is a black antiferromagnetic solid. As a mixed valence compound, its formula is sometimes written as Co II Co III 2 O 4 and sometimes as CoO•Co 2 O 3. [4]
The cobalt atoms are formally in the +3 oxidation state, hence the IUPAC name lithium cobalt(III) oxide. Lithium cobalt oxide is a dark blue or bluish-gray crystalline solid, [ 4 ] and is commonly used in the positive electrodes of lithium-ion batteries .
The (β) form of cobalt(II) hydroxide has the brucite crystal structure, i.e. the arrangement of the atoms in the crystal are the same as the arrangement of the atoms in Mg(OH) 2. The Co(II) centers are bonded to six hydroxide ligands. Each hydroxide ligand bridges to three Co(II) sites.
