Abstract: The microstructure of polydomain tetragonal zirconia (t'-ZrO2), i.e., a ZrO2 modification exhibiting ferroelastic behavior, is studied by high-voltage electron microscopy. This material consists of three domain variants of the tetragonal phase with their c-axes nearly orthogonal to each other, Always two variants of these platelike domains are alternately arranged, forming elongated regular colonies, Hence, in both variants the common habit plane of the domains is a {110} twin plane. The colonies are of columnar shape with a [111] longitudinal axis. They are bound by {110} planes, too, which are twin planes for the domains in the contiguous colonies. Owing to their particular structure and the helical arrangement of the adjoining colonies, the material remains coherent and pseudocubic over large macroscopic regions, although it is formed by different tetragonal domains.
