Abstract
An ultrapure mineralizer is formed by vaporization, condensation, and delivery of a condensable mineralizer composition. The mineralizer has an oxygen content below 100 parts per million. The ultrapure mineralizer is useful as a raw material for ammonothermal growth of bulk group III metal nitride crystals.
