The paper presents the results of the study of aluminosilicate glass that contains 0.77 wt% of F- anions. The results show that the critical size of glass particles at which the surface mechanism of crystallization changes to volume crystallization is in the vicinity of 0.075 mm in this glass. The temperature of the maximum nucleation rate was determined to be T-n = 680 degrees C, and it is higher than the transformation temperature T-g. At crystallization temperatures up to T-c = 950 degrees C, the crystal phase of leucite is formed, alone. Above this temperature, besides the main phase of leucite, two other phases, diopside and phlogopite appear. The activation energy of crystallization E-a = 319 +/- 23 kJ/mol was determined. The results also show that the activation energy does not depend on the crystallization mechanism in this glass. The value of the Avrami parameters is n = 1.45. Microstructural studies confirmed the fact that volume crystallization of leucite takes place in this glass. The leucite crystals grow in form of equiaxial dendrites with pronounced anisotropy along the direction [001]. Kinetical and microstructural studies show that the process of leucite crystal growth occurs at the smooth atomic scale-faceted crystal/glass interfaces and that it is controlled by volume diffusion. During the isothermal heat treatment the structure of dendrites changes.
