el boro también forma el compuesto binario nitruro de boro, cuyo interés es alto ya que es isoelectrónico con el carbono y se encuentra en dos modificaciones estructurales: una es una una estructura en capa suave y lubricante similar al grafito, la otra (formada bajo alta presión) tiene una estructura tetraédrica muy dura y estable como la del diamante.
boron also forms the binary compound, boron nitride, which is of interest as it is isoelectronic with carbon and occurs in two structural modifications; one is a layer structure similar to graphite which is soft and lubricating, whilst the other (formed under high pressure) has a very hard, stable, tetrahedral structure as found in diamond.
