Abstract—The influence of the temperature of the primary heat treatment in the case of two-stage heat treat-
ment of glasses on the kinetics of precipitation of PbS nanocrystals and the structure of the glass-ceramic mate-
rials prepared has been investigated. The main structural parameters of the glass-ceramic material, such as the
radius of lead sulfide nanocrystals, relative volume of the crystalline phase, concentration of nanocrystals, and
dispersion of nanocrystal sizes, have been determined under different heat treatment conditions. It has been
demonstrated that a variation in the temperature of the primary heat treatment in the range below the glass tran-
sition temperature of the glass matrix makes it possible to control the nanocrystal sizes and to obtain close-to-
monodisperse size distributions of nanocrystals.
