Özet

ZnO doped calcium-silicate glasses in the composition of 47SiO2–24CaO–

6P2O5–2Al2O3–(21-x)Na2O: (x)ZnO (x = 1, 3 and 5, wt%) were produced by

the traditional melt-quenching technique. The effect of ZnO contribution

at various rates on the physical, structural and thermal characteristics of

the glass structure was investigated. Densities (ρ) and molar volumes (Vm)

of the glasses were determined by the Archimedes method. Its structural

properties were measured with FTIR (Fourier Transform Infrared) spectrum

and its thermal properties were measured with DTA (Differential Thermal

Analysis) device. Densities of the synthesized glasses ranged from 2.709 to

2.784 g.cm-3. It was discovered that ZnO plays a glass-forming role in the

structure by interpreting the peaks in the FTIR spectrum. Glass transition

(Tg), crystallization (Tc) and melting temperatures (Tm) of all glasses produced

using the DTA spectrum were determined.
