摘要
本文对K_2O—TiO_2—SiO_2—R_xO_y系统玻璃宝石性质进行了详细研究,确定了玻璃中高折射系数氧化物的种类和数量及不同基态光谱项稀土元素的作用,优选出折射率1.68～1.76、硬度6～6.5、双色效应较强的玻璃宝石组成配方和工艺条件。
In this paper, properties of K2O-TiO2-SiO2-RxOy system glass-gem has been studied in detail. It's determined that the variety and number of high refractive coefficient oxide in glass and the action of the rare earth elements with different base terms spectrum. The formulation compose and technology conditions of glass-gem that refractive index between 1.68-1.76, hardness letween6-6.5 and dichraic effect fairly good have been optimized
