Abstract
An example ferroelastic ceramic composition includes at least one compound having a relative chemical formula of AXBYC(1-X-Y)D. Element A, element B, and element C are independently selected from different members of the group consisting of yttrium, lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, and lutetium. Element D is selected from the group consisting of phosphate, niobate, and tungstate. X and Y are each equal to or greater than zero and less than one. X and Y are collective less than one.
