Abstract
Disclosed herein is a device for manufacturing a single crystal comprising: a furnace that includes a furnace wall; a crucible disposed on a first base plate within the furnace; where the first base plate has a porosity of 1 to 80 volume percent, based on a total volume of the first base plate; and where the first base plate does not comprise free flowing particles; an induction coil disposed inside the furnace wall and outside the crucible; and a refractory lining being disposed in an annulus between the furnace wall and the crucible.
Claims19
A device for manufacturing a single crystal comprising:
- a furnace that includes a furnace wall;
- a crucible disposed on a first base plate within the furnace;
- where a surface of the first base plate contacts a bottom surface of the crucible and where the surface of the first base plate that contacts the bottom surface of the crucible comprises ridges and channels;
- an induction coil disposed inside the furnace wall and outside the crucible;
- and
- a refractory lining being disposed in an annulus between the furnace wall and the crucible.
A method of growing a high temperature material, comprising:
- disposing a melt within a crucible in a furnace;
- where the furnace includes:
- a furnace wall;
- an induction coil disposed in an annulus between the crucible and the furnace wall;
- where the crucible is disposed on a first base plate within the furnace, further comprising contacting a bottom surface of the crucible to a surface of the first base plate, the surface of the first base plate that contacts the bottom surface of the crucible comprising ridges and channels;
- and
- drawing a boule from the melt within the crucible to grow the high temperature material.
