Abstract
There is provided a platy Mg-containing zinc oxide sintered compact containing 1 to 10 wt % Mg as a first dopant element and 0.005 wt % or more at least one second dopant element selected from the group consisting of Al, Ga and In, the balance consisting essentially of ZnO and optionally at least one third dopant element selected from the group consisting of Br, Cl, F, Sn, Y, Pr, Ge, B, Sc, Si, Ti, Zr, Hf, Mn, Ta, W, Cu, Ni, Cr, La, Gd, Bi, Ce, Sr and Ba, wherein the (002)-plane or (100)-plane orientation in the plate surface is 60% or more. The Mg-containing zinc oxide sintered compact of the present invention has excellent properties such as high orientation despite solid dissolution of Mg.
