Microbubble formation during crystallization of LiNbO 3 melts
Bubbles whose size ranged from sub-micron to ∼ 1 μm were observed along the interface in the interface liquid boundary layer of LiNbO 3 melts when fiber-shaped LiNbO 3 crystals were grown via laser-heated pedestal growth (LHPG). This method usually yields a very high temperature gradient near the so...

Summary: | Bubbles whose size ranged from sub-micron to ∼ 1
μm were observed along the interface in the interface liquid boundary layer of LiNbO
3 melts when fiber-shaped LiNbO
3 crystals were grown via laser-heated pedestal growth (LHPG). This method usually yields a very high temperature gradient near the solid-liquid interface leading to significant thermoelectric power which affects the distribution of LiNbO
3 intrinsic species in the melt. Supersaturation of OLi
− and/or O
2− ions at the interface were calculated to have a large enough total supersaturation to nucleate bubbles due to a combination of both solute build up and a significant temperature difference between the interface and the far-field liquid. |
