Description	Leucit (KAlSi2O6) je hlavní krystalickou fází ve většině živcových dentálních porcelánů používaných v zubním lékařství pro metalo-keramické náhrady. Přítomnost leucitu v porcelánové matrici zvyšuje hodnotu koeficientu teplotní roztažnosti výsledného kompozitního materiálu a umožňuje tak jeho spájení s kovovou výztuží. (cs) Leucite ceramics having high fracture toughness and suitable thermal expansion being useful for making ceramic-fused-to-metal restorations represents a very promising material for dental applications. The aim of our work is to replace existing technologies based on the crystallization from a melt by preparation of a composite material in which leucite and glassy matrix are synthesised separately. Both these phases are subsequently homogenised and sintered in a dentist laboratory. This technology ensures reproducible control of leucite ceramics microstructure, which is requited to improve its fracture toughness and persistence. In the present study preparation of leucite powders with controlled particle size distribution was investigated Leucite was prepared by ion exchange of analcime, the degree of ion exchange was determined by XRD and XRF analysis.
