Abstract
The kinetics and mechanism of isothermal crystal growth of K2TiGe3O9 from a glass of the same stoichiometric composition were studied. The crystal growth rate, U, in the range 1x10-11-1.27x10-10 m s-1 was experimentally determined in the temperature interval 540-600°C. In the range of high under-cooling, Δt, 435-375°C, spherical crystals growing at (374±19) kJ mol-1 was observed.
Pod izotermskim uslovima proučavana je kinetika i mehanizam rasta K2TiGe3O9 kristala iz stakla istog stehiometrijskog sastava. U intervalu temperature 540-600°C eksperimentalno su određene brzine rasta kristala, U, 1x10-11-1.27x10-10 m s-1. Pokazano je da se u oblasti visokih pothlađenja, Δt, 435-375°C, rast sfernih kristala ove faze odvija po mehanizmu zavojne dislokacije. Dobijena je energija aktivacije rasta kristala GD=(374±19) kJ mol-1.
