Alkaline co-precipitation products of soluble cobalt, manganese and nickel salts

Substance identity

Identification

Display Name:

Alkaline co-precipitation products of soluble cobalt, manganese and nickel salts

Molecular formula:

Co(OH)2(0.005-0.1)Co2O3(0.03-0.3)Mn3O4(0.01-0.1)MnO2(0.02-0.25)Ni(OH)2(0.35-0.91) The stoichiometry of (OH)x+Oy per metal component in the substance cannot be determined unambiguously from solely analytical data, since the composition of the present UVCB substance is highly variable (i.e. complexly mixed and poorly ordered at the atomic level). The composition of the UVCB substance can be estimated based on analytical examination in combination with a calculation that is based on the average oxidation number (NOx) in the sum of the elements Ni, Co, Mn. As a result, the following constituents in concentration ranges as described below can be identified in the UVCB: The sum of all constituents equals 1 and ranges are: • Co(OH)2: 0.005-0.1 • Co2O3: 0.03-0.3 • Mn3O4: 0.01-0.1 • MnO2: 0.02-0.25 • Ni(OH)2: 0.35-0.91
