Abstract
A process for growing crystals of an inorganic material by forming a solution of the material in a solvent for the compound, forming a film of the solution and etching the solvent from the film with an etching gas until crystals of the material form. The solution has a solidification temperature lower than the melting or sublimation temperature of the material and higher than the condensation temperatures of the etching gas and of reaction products formed by the etching. The etching temperature is between the solidification temperature of the solution and the melting or sublimation temperature of the material and is lower than the vaporization temperature of the solvent and solution and higher than the condensation temperatures of the etching gas and reaction products.
