Abstract

Zirconia-based ceramic articles produced by the Klein and Syntek Keramik firms (Germany) are investigated by the methods of x-ray, luminescent, and ultrasound analyses. The density, the porosity, ultimate bending strength at room temperature, Weibull's modulus, crack resistance, and Young's modulus are investigated for specimens cut from the articles and are compared with the properties of domestic specimens based on zirconia partially stabilized by Y2O3. The structure and the composition are investigated by the methods of scanning electron microscopy, petrography, and x-ray and chemical analyses. The high-temperature strength is measured and the structure of fractures caused by these tests is investigated by the method of scanning electron microscopy.
