Abstract
A method is provided of growing crystals from compounds that melt congruently with negligible volatilization. The composition of one or more crystal samples is measured. A determination is made of a deviation of crystal composition from congruency. A determination is made of an initial melt composition and a source material composition correction relative to the deviation. Crystals are grown using the composition correction to yield reproducible material for surface acoustic substrate manufacturing.
