Abstract

ABSTRACT. Studied glasses in the system 50P2O5-(49-x)SrO-1AlF3-xAl2O3 (mol%), 0≤x≤4.5, were prepared via the melt-annealing technique. The prepared samples are transparent amorphous network structures. Glasses are still transparent upon the heat treatment at 540 ºC for 4 hours. 27Al nuclear magnetic resonance (NMR) has been applied to determine the structural role of Al2O3. X-ray diffraction (XRD), Fourier transform infrared (FTIR), and Vickers hardness (Hv) measurements have been carried out. XRD spectroscopy is used to investigate the glasses' crystalline features. The crystallinity was enhanced via the heat treatment process. Some of investigated strontium phosphate glasses are recommended to be applied in dental applications.

应用于玻璃离子水泥的氧化铝改性磷酸锶玻璃的结构与性能

摘要采用熔融退火法制备了50P2O5-(49-x)SrO-1AlF3-xAl2O3 (mol%)(0≤x≤4.5)体系的玻璃。制备的样品为透明的非晶网状结构。在540℃下热处理4小时后，玻璃仍然透明。27Al核磁共振(NMR)已被应用于确定Al2O3的结构作用。进行了x射线衍射(XRD)、傅里叶变换红外(FTIR)和维氏硬度(Hv)测试。用XRD光谱分析了玻璃的晶体特征。通过热处理工艺提高了结晶度。所研究的部分磷酸锶玻璃推荐用于牙科应用。关键词:核磁共振，氧化铝，GIC, x射线衍射，磷酸锶化学。Soc。阿比西尼亚人。2023年,37 (3),653 - 662 .
