Ammonothermal Growth of Rhombohedral Boron Nitride

physica status solidi (b), Volume 262, Issue 12, December 2025.
Boron nitride crystals are grown using the ammonothermal technique in a temperature‐induced solubility gradient of BN dissolved in a solution of supercritical ammonia using sodium as the mineralizer. The grown BN crystals harvest off the autoclave walls, and cubic BN seeds are characterized as hexagonal and rhombohedral phases of BN. Boron nitride (BN)
