At a boron nitride plant in New York, a newly installed technology exceeded required performance criteria and helped a plant with an air pollution control problem remain a part of the local industrial community.
Boron nitride is a product obtained by heating a mixture of boric acid and tricalcium phosphate in an electric furnace with an atmosphere of ammonia. The compound is a fine white powder with a high resistance to thermal shock, making it an excellent refractory material. Its graphite-like hexagonal plate structure makes it useful as a lubricant in some applications. The compound is used commercially in electronics, ...
