The article presents a chemical analysis and static mechanical strength tests on samples, with a geometry suggested by the authors. The market of dental materials is one of the most dynamically developing markets in the world. The materials used in the dental prosthetics must feature high biocompatibility, aesthetics and durability. In particular, the tests for materials used for dental crowns are widely developed. The test results related to the analysis of physical and chemical properties are used to improve the quality of services provided by the dental practices. The authors presented a newly developed method to prepare the mini-samples. 120 samples in 4 test groups were prepared: X-ray diffraction, derivatography, spectral analysis, 3-point bending static test. A chemical analysis showed that the tested material - zirconium dioxide is not susceptible to changes in temperature, and also showed numerous inclusions of other elements in the material.
