APPARATUS AND METHOD FOR PRODUCING A MULTICRYSTALLINE MATERIAL HAVING LARGE GRAIN SIZES

摘要

A crystal growth apparatus is disclosed comprising a crucible, optionally contained within a crucible box, on a crucible support block, wherein the bottom of the crucible, the bottom plate of the crucible box, if used, and/or the crucible support block comprise at least one cavity configured to circulate at least one coolant therein. Also disclosed is a method of preparing a crystalline material using the disclosed crystal growth apparatus as well as the resulting crystalline material, having larger overall grain sizes.
