Published: with international search report (Art. 21(3)) (54) Title: SHAPE MEMORY CERAMIC PARTICLES AND STRUCTURES FORMED THEREOF FIGURE 2A ► Loading t unloading (57) : There is provided a shape memory ceramic structure including an aggregate population of crystalline particles. Each crystalline particle in the population, of crystalline particles comprises a shape memory ceramic particle material. Each crystalline particle in the population of crystalline particles has a crystalline particle extent that is between about 0.5 microns and about fifty mi - crons. At least a portion of the population of crystalline particles has a crystalline structure that is either oligocrystalline or mono - crystalline.
