Fundamentals of Flux Growth

Chapter
Part of the NATO ASI Series book series (NSSB, volume 210)

Abstract

“Flux growth” is the name given to crystal growth from high temperature solutions, where the “flux” is typically a molten salt or oxide used as a solvent. The use of this word “flux” is derived from its more general usage for a substance which reduces the melting temperature, or dissolves oxides as in soldering. The principles discussed here can normally be applied to metallic solvents also. Another term which overlaps with flux growth is growth from non-stoichiometric melts, where a substantial excess of one component of a melt can be considered to be the solvent for the crystallizing phase. This article will concern the growth of bulk crystals from oxide or molten salt solutions where the solute concentration is normally from 1% to 30% (molar or weight fraction) and the temperature of crystal growth is from 300–1800°C.
