Abstract
RICE and Freamo prepared the well-known Rice's blue material from hydrazoic acid by thermal decomposition and also by passing the acid through an electric discharge, the products of both treatments being, in part, condensed on a ‘cold finger’ at 77° K.1,2 Attempts to prepare Rice's blue material from other chemical compounds—ammonia, hydrazine—and from mixtures of nitrogen and hydrogen proved unsuccessful2.
