Introduction Improvement of properties of traditional ceramic materials and creation of new ceramics is impossible without expanding the range and improving the quality of initial powders and changing their chemical composition.
The development of new technologies, principles for the selection of additives contributes to the creation of materials with improved (often unique) physical and technical characteristics, or with a number of special properties.
