No, boron nitride is often used as an insulator in the semi-conductor industry.
NASA used Boron Nitride in many different ways. It was used as a catalyst when starting Saturn rocket engines. Boron Nitride is also used in one form to protect the outside of the spacecraft. Boron Nitride is one of the hardest chemicals known to man.

You think probable to boron nitride (borazon); but other nitrides (of titanium, zirconium, vanadium, niobium, etc.) are also very hard. But no one equal the hardness of diamond.
Boron is use in doping semiconductors, modifying their electrical properties. Boron oxide (B2O3) is used in glassmaking and ceramics. Borax (Na2B4O7.10H2O) is used in making fiberglass, as a cleansing fluid, a water softener, insecticide, herbicide and disinfectant. Boric acid (H3BO3) is used as a mild antiseptic and as a flame retardant. Boron Nitride's hardness is second only to diamond, but it has better thermal and chemical stability, hence boron nitride ceramics are used in high-temperature equipment. Boron nitride nanotubes can have a similar structure to carbon nanotubes. BN nanotubes are more thermally and chemically stable than carbon nanotubes and, unlike carbon nanotubes, boron nitride nanotubes are electrical insulators. Boron carbide (B4C) is used in tank armor and bullet proof vests.
