    • Abstract

       

      The authors examine the boric oxide—ammonia route with special stress on the yield and composition of the intermediate addition compound (BN)x(B2O3)y(NH3)z. It has been concluded that B2O3 and NH3 present in the addition compound formed between 350°C and 900°C cannot be further reacted to convert the B2O3 into BN and the BN yield remains at around 66%. A formula (BN)12·7(B2O3)7·5NH3 has been suggested for the addition compound.
