Ag Katkılı NaPO3 Camları: Sentez ve Karakterizasyon

Bu çalışmada, Ag katkısının NaPO3 camlarının yapısal özellikleri ve morfolojisi üzerine etkileri araştırıldı. Buamaçla farklı oranlarda Ag içeren NaPO3 camları 850 °C’de üretildi. Hazırlanan numunelerin karakterizasyonu Xışını kırınımı (XRD), Fourier dönüşümlü kızılötesi (FTIR) spektroskopisi ve taramalı elektron mikroskopisi (SEM)teknikleri kullanılarak gerçekleştirildi. Elde edilen tüm numuneler için gözlemlenen tek faz, ortorombik kristalyapıdaki NaPO3’tür. Ag katkısıyla ikincil bir fazın oluşumu gözlenmedi. Ag katkılanmasının, sodyum fosfatcamlarının kristal büyüklüğü, kristalleşme miktarı ve örgü parametrelerinde belirgin değişimler meydana getirdiğigörüldü. FTIR spektrumlarında fosfat grubuna ait bantlar tespit edildi. Morfolojinin Ag katkısından etkilendiğigözlendi.

Ag-doped NaPO3 Glasses: Synthesis and Characterization

In this study, the effects of Ag-doping on the structural properties and morphology of NaPO3 glasses were investigated. For this purpose, Ag-containing NaPO3 glasses were produced at 850 °C. The characterization of the as-prepared samples was performed using X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM) techniques. The as-observed single phase for all the asobtained samples is the NaPO3 having the orthorhombic crystal structure. The formation of the secondary phase was not observed. It was seen that the Ag-doping caused significant changes in the crystallite size, amount of crystallinity and lattice parameters. The bands related to the phosphate group were detected in the FTIR spectra. It was observed that the morphology was affected by Ag-doping.
