Zirconia has become an alternative to materials used in dentistry because it is characterized by high mechanical strength and a high aesthetic parameter of materials, which resulted in reduced strength and lack of material stability. Zirconia stabilized with yttrium oxide falls under the category of intelligent materials, it means that when applying the right force to the material geometry, the structure of the material - the arrangement of the crystals is transformed from tetragonal to monocyclic. Due to this phenomenon, this material may hinder the propagation of crack propagation. The purpose of this article is physicochemical analysis that allows determining the distribution of aluminum compounds in the cross-section of zirconia, which was subjected to mechanical strength tests for three-point bending. The authors presented a method of producing ceramic samples, static tests of three-point bending strength, testing using an XRF X-ray spectrometer. The XRF analysis was performed by comparing the compound peaks for the external surfaces and cross-section.
