Single crystal growth of langataite (La3Ta0.5Ga5.5O14) by vertical Bridgman (VB) method along [21¯1¯0] in air and in an Ar atmosphere

Crystal growth and physical properties of shape-controlled La3Ta0.5Ga5.5O14 single crystals by micro-pulling-down method

“…According to the chemical analysis by the EPMA system, the main phase was composed of LTG with the cation ratio of La:Ta:Ga¼3.31:0.465:5.22. On the other hand, the secondary phase was La-Ta-O system and the generation of the La-Ta-O system in the LTG crystal was also confirmed in the previous report about the LTG crystal grown by the Bridgman method [11]. According to the previous report about the phase diagram of LTG [12], LTG is an incongruent material and a single crystal without secondary phases cannot be grown from the stoichiometric composition.…”

Growth and characterization of strontium-substituted Ca₂Al₂SiO₇ piezoelectric single crystals

“…Rectangular parallelepiped specimens with dimensions of 75 © 100 © 125¯m 3 were used in all experiments. Diffraction intensities and the related angles were measured at room temperature using a Rigaku AFC5S automated four-circle diffractometer.…”

LGT (La 3 Ga 5.5 Ta 0.5 O 14 ) langatate bulk crystal grown from the melt by Czochralski technique and characterization

“…LGT by micro-pulling-down method [6], by vertical Bridgman method [7], and by Czochralski method [2,4,8,9]. That the composition of LGT crystals depends significantly on preparation conditions such as a charge preparation, growth atmosphere and growth conditions.…”
