Abstract
This oxide sintered compact is obtained by mixing and sintering powders of zinc oxide, tin oxide and indium oxide. As determined by X-ray diffractometry of this oxide sintered compact, the oxide sintered compact has a ZnSnOphase as the main phase and contains an In/InO—ZnSnOsolid solution wherein In and/or InOis solid-solved in ZnSnO, but a ZnInOphase (wherein x, y and z each represents an arbitrary positive integer) is not detected. Consequently, the present invention was able to provide an oxide sintered compact which is suitable for use in the production of an oxide semiconductor film for display devices and has both high electrical conductivity and high relative density. The oxide sintered compact is capable of forming an oxide semiconductor film that has high carrier mobility.
