Czochralski Growth of Oxide Crystals: Numberical Simulation and Experiments

By Jyotirmay Banerjee and K. Muralidhar

A mathematical model that explores the basic transport phenomena in a Czochralski process, their interaction and influence on the growth of high quality oxide crystals is presented. Steady state simulation has been carried out for the full Czochralski domain including the melt, crystal and gas within the enclosure. The numerical code has been modified to simulate continuous growth of a YAG crystal under quasi-steady conditions, by taking into account the increase in crystal height and a reduction in the melt volume. Experiments using liquid crystal thermography have been conducted to study the interaction between buoyancy and crystal rotation, as well as for validating the computer codes.
