Glassy carbon is widely practiced as an electrode material in electrochemistry, as considerably as for high temperature crucibles and as a part of some prosthetic devices.

The crystalline carbon electrode is one of the widely used working electrodes. It is a good inert electrode with good electrical conductivity, high hardness, high brightness, high hydrogen potential, wide range of polarization and chemical stability. It can be used as an inert electrode directly for the anodic solution, voltammetric determination of the cathode and the Valencia ion, and it can also be used as a chemically modified electrode.
