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.
