摘要:

利用熔融和晶化技术制备掺钕磷酸盐玻璃陶瓷。 采用差热分析、X射线衍射、扫描电子显微镜、紫外可见近红外分光光度计及荧光光谱仪对材料进行表征和分析。 结果表明,在490~540 ℃核化1~2 h,在550 ℃晶化1~3 h,可制得主晶相为Al2SiO5的透明玻璃陶瓷。 其透过率可达69%,晶粒平均尺寸为90 nm,并随热处理时间的增加逐渐增大,但透过率降低。 由于Nd3+在热处理后进入到Al2SiO5晶相中,使荧光谱线在1 056 nm处峰值比原始玻璃强度大。

Abstract:

The transparency phosphate glass-ceramics which is doped neodymium is prepared by melting and the technology of crystallization. And it is characterized by DTA,XRD,SEM,fluorescence spectrometer. It indicates that the transparent glass-ceramics whose main crystal phase is Al2SiO5 would be made.The temperature of nuclear generation is at the range from 490℃ to 540 ℃,and the time of treatment is about 1h~2h.Then the temperature of crystallization is at 550℃, and the time of treatment is about 1h~3h..The range of grain size is 90nm.Because of the concentrating of Nd3+ in the crystal phase after the heat treatment,the intensity of the peak which belongs the sample is bigger than the intensity which belongs the host glass at 1056nm in fluorescence spectra.

Key words: melting method, phosphate, glass-ceramics
