Abstract

Boron nitride was from boric acid-diethanolamine or -triethanolamine condensation products by their pyrolysis in a nitrogen flow. The condensation products obtained from boric acid-diethanolamine system (molar ratio 1:1 and 2:3) were glassy solids and had a polymeric structure containing the B-O-C bond. Monomeric triethanolamine borate, which contained both B-O-C and coordinate B-N bonds, was formed from boric acid-triethanolamine system. Pyrolysis of these condensation products in N//2 flow at 1400 degree C yielded boron nitride. A small amount of B//4C was also formed, depending on the molar ratio or on the carbon content of the condensation products.
