Superhard Materials Glossary

• Alloy

  A mixture containing two or more metallic elements or metallic and nonmetallic elements usually fused together or dissolving into each other when molten.

• CBN

  A short form for Cubic Boron Nitride.

• Chemical Inertness

  A chemical analysis of an abrasive.

• Cube

  A three-dimensional shape with six square or rectangular sides.

• Crustal Movement

  Movement resulting from or causing deformation of the earth's crust.

• Carats

  Such as a weight unit for jewelries.

• Carbonaceous

  Relating to or consisting of or yielding carbon.

• Cemented Carbide

  A kind of alloy material made through powder metallurgy.

• Cleavage Plane

  The bility of mineral crystals breaking up under the external force and showing the crystallization direction with the smooth plane is called cleavage, and the planes are called the cleavage planes.
