Rezumat:
Langasite family compounds have attracted a lot of attentions because of the combination of a number of nice material properties such as high piezoelectric coupling, temperature compensation and low acoustic loss. Another very important property is that the compound melts congruently so that large single crystals of langasite can be produced by the conventional Czochralski melt pulling technique. This makes the commercial scale production feasible. Synthesis, growth conditions, and structural considerations are presented.
