Crystallization of Barium Aluminum Borate Glasses—Rhodium as a Specific Catalyst
Experimental work is described on the nucleation and crystallization of various BaO-B2O3-Al2O3 glasses both with and without metallic nucleating agents. Previous studies of the crystallization behavior of glasses are reviewed. Experiments are reported which indicate that small additions of metallic rhodium catalyzed internal crystallization in glasses of the barium aluminum borate system. Other noble metals were studied, but none was as effective as rhodium.
