Method for preparing calcium copper titanium oxide compound powder
The invention discloses a method for preparing a calcium copper titanium oxide compound powder. The method comprises the following steps: proportioning titanium dioxide, copper nitrate and calcium nitrate according to the stoichiometric proportion of CaCu3Ti4O12, and carrying out solution preparation, heat treatment, pulverization and the like to finally prepare the calcium copper titanium oxide compound powder with uniform composition, favorable dispersity and pure phase. The low-price titanium dioxide is used instead of the high-price isopropyl titanate or tetrabutyl titanate, thereby lowering the production cost. No catalyst is needed in the preparation process, thereby lowering the environmental pressure of the production technique. The holding time is obviously shortened in the calcination process, thereby effectively lowering the energy consumption. The method simplifies the technique for preparing a calcium copper titanium oxide compound powder by a sol-gel process, greatly lowers the cost and reduces the environmental pollution. The prepared CaCu3Ti4O12 powder has the advantages of uniform composition, favorable dispersity and pure phase.
