Characterization of LiNbO3 micro single crystals grown by the micro-pulling-down method

Modification of the micro-pulling-down method for high-temperature solution growth of miniature bulk crystals

“…The micro-pulling-down (m-PD) method which has been developed at the Fukuda Laboratory of Tohoku University [1] is usually believed as being suitable only for melt growth of congruently melting compounds. Since the melt is delivered to the growth interface through the narrow capillary channel, only the diffusion controlled growth mode is considered [2].…”

Evaporation induced diameter control in fiber crystal growth by micro‐pulling‐down technique: Bi4Ge3O12

“…Melting, melt homogenization, and seeding were shortened as much as possible. The raw materials were not melted at the stage of preliminary heating of the system (surrounding furnace and the after-heater [1][2][3][4]). Heating of the crucible and following melting of raw materials began just before seeding.…”

“…Number of congruently melting fiber crystals including LiNbO 3 (LN) [1][2][3], Ca 3 (Li,Nb,Ga) 5 O 12 (CLNGG) [4], Y 3 A1 5 O 12 (YAG) [5,6], Bi 4 Ge 3 O 12 (BGO) [7], Tb 3 Ga 5 O 12 (TGG) [8], etc. was grown by micro-pulling-down (µ-PD) technique ( Fig.…”

Composite Oxide Fibres Grown by Internal Crystallisation Method

“…Single crystalline fibres, which are much more creep-resistant, are normally obtained by technologies of low productivity rates such as Edge Feed Groeth [9], Laser Heated Pedestal Growth [10], and µ-pulling down [11]. Fibres produced by these methods are characterised by a nearly ideal microstructure, but they are too expensive to be used as reinforcement for structural composites [6].…”
