The Mechanical Activation Of Zinc Oxide, Copper Oxide, Nickel Oxide, Energy Storage Research

The energy changes of mechanically activated Zinc oxide, cupric oxide, nickel monoxide were studied in order to investigate the relation between mechanically activated storage energy and the way of activation, and to provide a fundamental basis for the mechanical activation . The main conclusions made are as follows:(1) The parameters of the Calvet HT-1000 microcalorimeter were calibrated systematically with a new electric caliboration device redesigned. The parameter of the instrument K is 0.4105J·V^-1·s^-1. The reliability of the microcalorimeter was verified. At 298.15K, the heat of 1mol KC1 in 200mol pure wate is 17.61 kJ·mol^-1.The result is close to that of the literature which is 17.56 kJ·mol^-1, with a relative error 0.34%.(2) The mechanically activated stored energy of Zinc oxide, cupric oxide, and nickel monoxide increases with the increased grinding time. The mechanically activated stored energy of Zinc oxide by planetary ball mill is about 26.7kJ·mol^-1, by attritor ball mill is about 27.2 kJ·mol^-1. The mechanically activated stored energy of cupric oxide by planetary ball mill is about 23.5kJ·mol^-1, by attritor ball mill is about 24.2kJ·mol^-1. The mechanically activated stored energy of nickel monoxide by planetary ball mill is about 30.4kJ·mol^-1, by attritor ball mill is about 32.2kJ·mol^-1.(3) The increase of the specific surface energy of mechanically activated Zinc oxide, cupric oxide and nickel monoxide is not the main reason. The mechanically activated stored energy is closely related to the lattice distortions.(4) The efficiency of attritor ball mill is higher than which of planetary ball mill, got higher activated storage energy in a shorter time.
