摘要
选择ＢａＯ－ＳｒＯ－ＴｉＯ２－ＳｉＯ２玻璃系统，采用特殊的定向析晶工艺，获得透明极性微晶玻璃．测定了材料的显微结构、光谱透过率等性能．研究结果表明：该透明微晶玻璃在波长为４００ｎｍ—５μｍ区间内有较高的透过率，沿晶粒生长方向的压电常数ｄ３３为９．５×１０－１２Ｃ／Ｎ，二阶非线性光学系数χ（２）为１．２×１０－１３ｍ／Ｖ．
The oriented crystallization in the system of 0.2BaO-1.8SrO-TiO 2-2.9SiO 2 was studied,and the transparent glass-ceramics were obtained by recrystalling from glass. The main crystal phase and the properties of the glass-ceramics were determined.The results show that the glass-ceramics have high transmission rate in the range of 400nm—5μm,the piezoelectric constant d 33 is 9.5×10 -12 C/N and the second_order nonlinear susceptibility χ (2) is 1.2×10 -13 m/V.
