Abstract

We report for the first time the growth of large size single crystals of KLiYF₅ (KLYF) by TSSG method using the conventional weight-feed-back automatic diameter control Czochralski puller. We also succeeded to grow for the first time single crystals of KLiGdF₅ (KLGF). We constructed a new pseudo-binary phase diagram for the KF-LiF-YF₃ system. Both KLYF and KLGF melt peritectically. They both showed high optical anisotropy as we expected. However, this anisotropy comes from the layer structure of the crystal which also gives a perfect set of (010) cleavage plane. At present, this is a problem preventing us to get crack-free single crystals.
