The growth of strain-free Y3Al5O12 single crystals

Czochralski growth of oxides

“…Furthermore, it was assumed that a conical interface was necessary to maintain stable growth and that a flat or convex interface shape would result in unstable growth. One of the first attempts to modify the shape of the growth interface was by Cockayne et al [27]. They showed that under the proper conditions, the shape of the growth interface could be controlled by the crystal rotation rate.…”

Revisiting the Hydrothermal growth of YAG

“…While the field of optics has advanced at a rapid pace to develop and improve such lasers it would seem that the crystal growth of garnets has not advanced quite at the same pace. Though the Czochralski and flux growth of YAG have enjoyed several advances (in particular the understanding of compositional variations, interface shape and diameter control [9][10][11][12]), YAG crystals are still grown much in the same way as they were in the early days of laser materials research some 40-50 years ago [13][14][15][16].…”

Growth characteristic of Al2O3/Y3Al5O12 (YAG) eutectic ceramic in situ composites by laser rapid solidification

“…α > 2 (α = ξ S f /R; where S f /R and ξ, respectively, are the entropy of fusion of eutectic phases and a crystallographic factor less than but almost equal to 1), which results in an anisotropic and faceted growth of Al 2 O 3 phase at solid-liquid interface and the second phase of YAG growing and interweaving cooperatively with Al 2 O 3 phase. Moreover, the YAG phase normally also grows in a faceted manner [22]. The spacing among the lamellae of the faceted-faceted eutectic growth is not constant, resulting in an irregular morphological structure.…”
