Floating-Zone Growth of Single Crystal Olivine $[(Mg_{1-x}Fe}_{x})_2SiO_4]$
Floating Zone법에 의한 올리빈 $[(Mg_{1-x}Fe}_{x})_2SiO_4]$ 단결정 성장
Abstract
Large single crystals of olivine were grown by using image furnace(floating zone furnace)under controlled partial pressure of oxygen. The transparent crystals have maximum sizes 65mm in length by 7mm in diameter. When partial pressure of oxygen was decreased, the portion of secondary phases in crystals were increased so that it made crystals dark brown. The secondary phases were proved to be solid solution of Mg, Si, and Fe by electron microprobe analysis. Mg was major portion and the rest was minor.
커다란 olivine 단결정을 image furnace(floating zone furnace)를 사용하여 산소분압의 조절하에서 성장시켰다. 결정은 투명하였으며 길이가 65mm, 직경이 8mm였다. 산소분압이 감소할 때 결정내 제2상이 증가하여 결정을 엷은 갈색에서 짙은 갈색으로 변화시켰다. 이 제2상은 EPMA결과 Mg가 기저를 이룬 것에 Si와 Fe가 solid solution을 형성한 것이었다.
