Claim Text:
1. A method for growth of group III metal nitride crystals, comprising: providing a manifold comprising at least one first transfer vessel, a source vessel containing a condensable mineralizer composition, and a receiving vessel; chilling the at least one first transfer vessel; transferring a quantity of the condensable mineralizer composition to the at least one first transfer vessel via a vapor phase and causing condensation of the condensable mineralizer composition within the at least one first transfer vessel; measuring the quantity of the condensable mineralizer composition within the at least one transfer vessel; transferring the condensable mineralizer composition to the receiving vessel; and utilizing the transferred condensable mineralizer composition or a composition formed from the condensable mineralizer composition as a mineralizer for ammonothermal crystal growth of a group III metal nitride boule, the ammonothermal crystal growth being performed at a temperature of at least about 400 degrees Celsius.
