ABSTRACT:
Sheets of meltable materials are produced by causing the molten material to flow out on a molten support bath of material immiscible therewith having a higher specific gravity than the meltable material. The meltable material is allowed to advance to its equilibrium thickness and that thickness is controlled by adjusting the composition of the molten support material so as to increase the wettability of the meltable material to the molten support layer. The molten sheet is directed into a cooler zone where it solidifies into a crystalline sheet. The process is especially useful for the production of thin semi-conductor crystals. Specifically, thin silicon crystals are grown on a molten lead support by adding tin to the molten support.
