Abstract
Nickel oxide(NiO) powder is prepared by decomposition of basic nickel carbonate (mNi(OH)(2).nNiCO(3).xH(2)O) in microwave field with NiO see d as a microwave absorbing additive. Basic nickel carbonate(BNC) can d ecompose completely to NiO powder in a short time. Firstly, the heat f or BNC decomposition is provided by NiO seed which absorbs microwave a nd then by NiO product which also absorbs microwave. The decomposition process of BNC can be accelerated by increasing the amount of BNC, th e amount of NiO seed or the microwave field power. The size of NiO pow der product is about 180nm when the size of BNC used is about 160nm.
