Nickel Carbonate
Table of contents
Key Data
Formula: Ni4CO3(OH6)(H2O)4
CAS: 3333-67-3 or 29863-10-3
Other names: Basic nickel carbonate, nickel (II) carbonate, nickelous carbonate
Appearance: Light green powder
Solubility in water: 93mg/L
Thermal decomposition: H2O is given off from 90 - 200°C as Ni4CO3(OH6)(H2O)4 → Ni4CO3(OH6) + 4H2O,
then H2O and CO2 are given off from 270 - 420°C as Ni4CO3(OH6) → 4NiO + CO2 + 3H2O
