초록
기존의 합성방법에 사용되는 백금 도가니의 단점을 보완할 수 있는 알루미나 도가니를 사용하여 천연 및 기존 의 합성루비와 유사한 적색의 투명한 결정을 성장시켰다. PbO-B2O3 가 혼합된 플럭스를 사용하여 915~1350℃의 온도에서 약 240시간 실험 후 최대 9.02 × 6.36 mm 투명한 적색의 결정이 성장되었다. 이 결정을 보석학적 기초검사를 통하여 굴절 률, 내포물, 비중 등의 특성과 FT-IR, UV-VIS spectrometer 및 XRD 를 사용하여 기존의 합성루비 및 천연루비의 특성과 비 교 분석하였다.
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 915~1350℃ for 240 h, using PbO-B2O3 mixture. The grown ruby crystals with 9.02 × 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.
