Abstract
A sintered composite oxidecomposed mainly of zinc, aluminum, titanium and oxygen, the atomic ratio of the elements satisfying the following equations (1) to (3), the sintered composite oxidecomprising particles having a hexagonal wurtzite structure containing zinc oxide as the major component and having a mean particle size of no greater than 20 μm, and particles having a ZnTiO-like structure and/or ZnTiO-like structure containing aluminum and titanium and having a mean particle size of no greater than 5 μm, and containing no particles with a spinel oxide structure of zinc aluminate with zinc and aluminum in solid solution, and a manufacturing method for the same.(Al+Ti)/(Zn+Al+Ti)=0.004-0.055  (1)Al/(Zn+Al+Ti)=0.002-0.025  (2)Ti/(Zn+Al+Ti)=0.002-0.048  (3)[In the equations, Al, Ti and Zn represent the contents (atomic percents) of aluminum, titanium and zinc, respectively.]
