A crystal of borazon is strikingly similar to that of diamond, but while diamond "
burns up " in air at about 800°C, borazon withstands 1,800°C. A good deal is
known about the hexagonal form of boron nitride in which the atoms are
arranged in a ...
Now Dr. Robert H. Wen- torf Jr., young GE physical chemist and creator of
borazon, has accomplished the "impossible" by making such a substance.
Simplest evidence of his feat is the familiar scratch test for hardness. Traditionally
, "only a ...

Boron nitride has a structure similar to graphite. Hybridisation at B and N in it is
sp2. Boron nitride is also known as white graphite. □ A hard substance known as
borazon is obtained when boron nitride is heated at 3000°C and 10,000 atm.
Borazon crystals scratch diamonds and stay hard in temperatures at which
diamonds burn. Officially named "cubic boron nitride," each colored grain is
about as hard as a diamond and withstands 3500 degrees F., while a diamond
burns at ...
