Bulk crystal growth and characterization of non-centrosymmetric single crystal CaTa ₄ O ₁₁

This is the authors' abstract. We don't add key points for this paper.

For the first time, high-quality bulk single crystals of CaTa 4 O 11 were grown by the floating-zone method, and thus the current phase-diagram was revised for the stoichiometry CaO·2Ta 2 O 5 , showing a congruent melting behavior.
