적외선 할로겐 lamp를 열원으로 하는 image furnace을 사용하는 Floating Zone process를 이용하여 Spodumene$(LiAlLi_2O_6)$ 단결정을 성장하였다. 결정의 길이는 50~60mm, 직경 6~8mm였고 dopant에 따라 녹색, 흑색, 연한 녹색의 결정을 얻었다. Spodumene 조성의 고찰을 위해 XRD와 FTIF을 조사하였으며, Laue back reflection pattern을 통해 결정성을 고찰하였다. 결정의 광투과도 측정을 위해 optical transmittance를 측정하였다.
Spodumene$(LiAlLi_2O_6)$ single crystal was grown by Floating Zone process using the image furnace having the halogen lamp as heat sources. The crystal had the dimension of 50~60mm length and 6~8mm diameter. The colors of as-grown crystals were green, black and pale green respectively. The composition of the crystal was analized by XRD and FUR measurement. Growth orientation was examined by Laue back reflection pattern and for measuring the light transmittance, OPtical transmittance was measured.
