Sažetak
Microstructure of lucite glass-ceramics for dental use was investigated using X-ray diffraction, FT-IR spectroscopy and laser Raman spectroscopy. Main features of the FT-IR and laser Raman spectra were similar to those of silicate glasses containing Al3+, or other M(3+) (M = metal), as network forming ions. Two weak IR bands at 640 and 543 cm(-1) were typical of all lucite-type glass-ceramics and these bands disappeared with the conversion of glass-ceramics into the glass state. The laser Raman spectrum of lucite-type glass showed a broad band with center at approximate to 4600 cm(-1) due to fluorescence/luminescence spectral feature with two luminescence sharp peaks at 5037 and 5007 cm(-1). The results were compared with those obtained for different silicate glasses. [References: 20]
