IN-SITU YBA2CU3OX GROWTH-RATE ANALYSIS

The growth of large mono-domian YBa2Cu3Ox (Y-123) pellets has been stu died with levitation applications in mind. The Top-Seed Melt-Texturing method (TSMT) was applied using a SmBa(2)Cu(3)Ox seed. During the pro cess, a video recording was made of the evolution on the sample surfac e. Using this data, a model for the growth of mono-domains, inside a t emperature window, is discussed and a strategy is defined to overcome the limitation in crystal size. 40 mm diameter mono-domains have alrea dy been obtained following this strategy.
