Abstract: Disclosed herein is a furnace and a method of growing a high temperature oxide crystal. The furnace includes a cylindrical furnace wall, an induction coil disposed within the cylindrical furnace wall, a quartz tube disposed within the induction coil, a refractory lining disposed within the quartz tube, and a crucible disposed within the refractory lining, the crucible including a melt therein. A lid placed on the crucible. An asymmetric configuration of at least one of the crucible, the refractory lining, the quartz tube, the induction coil and the lid within the cylindrical furnace wall creates a thermal gradient that causes a cold spot in the melt to migrate from a first location to a second location of the melt. A rod having a seed crystal at an end thereof is lowered into the crucible to draw a boule from the melt via the seed crystal from the first location.

Abstract: A furnace and a method of growing a high temperature oxide crystal in the furnace. The furnace includes a crucible having a melt therein and a heating element for generating heat in the melt. A thermal element within the furnace produces a thermal gradient within the melt to draw a cold spot of a convection cell of the melt away from a seed location of the crucible. A seed crystal is drawn from the melt at the seed location to form a boule to grow the high temperature oxide crystal.
