Summary: | The glass was prepared by the standard melt-quenching technique. The
crystallization of powder glass from the system Li2O-Al2O3-GeO2-P2O5 was
studied. The investigations were performed under non-isothermal and
isothermal conditions using the AAS, DTA, XRD and FTIR methods. The aim of
this research was to study the ease of glass formation, crystallization and
crystal structure of obtained phases. The results showed that the glass
crystallizes by primary crystallization. LiGe2(PO4)3 was formed as the
primary phase, until detectable traces of GeO2 were formed as secondary. The
influence of particle size of the glass powder samples in the range 0-1 mm
on the temperature of the DTA crystallization peak, Tp, the peak height
(dT)p and the parameter Tp2/(DT)p was studied. It was demonstrated that for
the particle size in the range of 0.05-0.35 mm surface and volume
crystallization were significant, while the particle size >0.35 mm according
to the volume crystallization was dominant. |
