摘要
通过在实验中调整配方的剂量和热处理温度,得到与红宝石的折射率和颜色相近的玻璃。实验表明,其折射率随Pb质量分数的增加而加大,Pb的质量分数对玻璃的软化温度和流动性有明显的影响。运用Pb质量分数为30%的玻璃进行了天然红宝石充填实验,结果表明,高Pb玻璃充填处理红宝石样品中的裂隙降低,颜色有一定程度的提高和改善。
The glass with colour and refrective index resemblance to ruby is obtained by adjusting the proportion of formula and heat-treatment temperature in the experiments. The results show that the refrective index increases with the content of Pb. The content of Pb has the obvious effect on tg and liquidity of glass. The filling experiments on the natural ruby samples by glass containing 30 % Pb show that the fissures decrease and the colour and quality are improved in the treated samples.
