Abstract

In this study, ruby single crystals were successfully grown by flux method using an alumina crucible. The alumina crucible can be a substitute for the platinum crucible of high price. The ruby single crystals were grown in the temperature range of $915{\sim}1350^{\circ}C$ for 240 h, using $PbO-B_2O_3$ mixture. The grown ruby crystals with 9.02 ${\times}$ 6.36 mm in size exhibited red color and were transparent. The optical and structural properties were examined by UV-VIS spectrometry, FTIR and XRD. The optical properties of theses crystals were similar to those of the natural ruby and synthetic ruby grown by other methods.

기존의 합성방법에 사용되는 백금 도가니의 단점을 보완할 수 있는 알루미나 도가니를 사용하여 천연 및 기존의 합성루비와 유사한 적색의 투명한 결정을 성장시켰다. $PbO-B_2O_3$ 가 흔합된 플럭스를 사용하여 $915{\sim}1350^{\circ}C$의 온도에서 약 240시간 실험 후 최대 9.02 ${\times}$ 6.36 mm 투명한 적색의 결정이 성장되었다. 이 결정을 보석학적 기초검사를 통하여 굴절률, 내포물, 비중 등의 특성과 FT-IR, UV-VIS spectrometer 및 XRD 를 사용하여 기존의 합성루비 및 천연루비의 특성과 비교분석하였다.
