使用X射线衍射(XRD)测量和Maker条纹技术对含有Ba2TiSi2O8晶相的BaO TiO2-SiO(2)结晶玻璃进行了检查。研究发现，成分接近Ba2TiSi2O8化学计量的结晶玻璃表现出块状结晶，而其他非化学计量成分Ba2TiSi2O8的结晶玻璃则表现出表面结晶。参数 AT（结晶起始温度与玻璃化转变温度之间的温度差）强烈影响本 BTS 玻璃的结晶行为。具有强c取向BaTiSi2O8相的30BaO-20TiO(2)-50SiO(2)透明表面微晶玻璃表现出二阶非线性光学常数d(33) = 6.1 pm/V。 (c) 2007 年 Elsevier B.V. 出版
The BaO TiO2-Sio(2) crystallized glass containing Ba2TiSi2O8 crystal phase was examined using X-ray diffraction (XRD) measurement and Maker fringe technique. It has been found that the crystallized glasses with a composition of close to the stoichiometric Ba2TiSi2O8 showed bulk crystallization, whereas other crystallized glasses with non-stoichiometric composition of Ba2TiSi2O8 showed surface crystallization. The parameter AT, the difference in temperature between the crystallization onset and the glass transition temperature, strongly affects the crystallization behaviors of the present BTS glasses. The 30BaO-20TiO(2)-50SiO(2) transparent surface crystallized glass with strong c-oriented BaTiSi2O8 phase showed its second-order non-linear optical constant, d(33) = 6.1 pm/V.
