Title: Preparation of single crystal
Inventor: HABA HARUO
IPC: C30B15/00
Filed: 1985-02-18
Abstract: PURPOSE:To prepare a large sized Bi-substituted Y-Fe-garnet of high quality in a short time by carrying out the growth of the single crystal utilizing a differential temp. flux pulling method based on a BaO-Bi2O3-B2O3 mixture. CONSTITUTION:A single crystal of Bi-substituted Y-Fe-garnet is prepd. by a differential temp. flux pulling method utilizing a BaO-Bi2O3-B2O3 mixture. If Bi2O3 is used a flux in the above-described method, elution of the components of crucible is caused due to corrosion of the crucible deteriorating the light absorbing characteristics because of contamination of the grown crystal. For the improvement of the corrosion resistance, utilization of BaO-Bi2O3-B2O3 mixture is preferred to be used in the constitution of the process of this inven tion instead of using Bi2O3 alone as flux.
