Ceradyne Boron Products provides a high purity, high density titanium diboride for applications in aerospace and chemical manufacture. The corrosion resistance of TiB₂ lends to advantages in extreme environments. For instance, TiB₂ can be used as a cathode material in aluminum smelting, replacing historical graphite cathodes and thus reducing greenhouse gas emissions.

TiB₂ has good electrical conductivity and can be shaped by EDM (electrical discharge machine) for sputtering targets.
