Sažetak
The processes of nucleation and crystallization of a polycomponent ZnO-Al2O3-B2O3-SiO2-TiO2-ZrO2 glass were studied. The methods used were isothermal and non-isothermal DTA as well as X-ray diffraction. The temperature of maximum nucleation rate was determined, it was established which crystal phases made the crystallization and the temperature range of the crystallization of each crystal phase was defined. Kinetic parameters for the crystallization of each phase in isothermal and non-isothermal conditions were determined. The superimposed peaks on DTA curves were separated using previously developed computer program.
