반응 단계
A solution containing titanium and metal ions is perpared by mixing 84.0 ml of 0.2 M titanium nitrate solution containing hydrogen peroxide (Ti/H2O2 ratio: 1.5), 116.0 ml of 0.2 M zirconium nitrate solution and 200.0 ml of 0.2 M lead nitrate solution. The solution containing titanium and metal ions is added dropwise with stirring to 400 ml of an aqueous alkaline solution containing 27.7 ml of ammonium hydroxide (28%), 3.9 ml of hydrogen peroxide (30%) and 3.9 g of ammonium nitrate, whereby a precipitate of complex peroxide is obtained. The precipitate is recovered by filtering, washed thoroughly with distilled water, dehydrated with ethyl alcohol, and dried at room temperature. The crystalline lead zirconate titanate, Pb(Zr0.58 Ti0.42)O3, is obtained by heating the resulting precipitate at a temperature higher than 600° C.
