Glassy carbon is imported glassy carbon
The glass carbon is abbreviated as glassy carbon, which is an amorphous carbon which is slowly heated to a high temperature (up to 1800 ° C) in an inert atmosphere in an inert atmosphere, and is suitable as an electron conductor material for an electrode. The table tennis bottom plate is also widely used.
The advantages of the glassy carbon electrode are good conductivity, high chemical stability, small thermal expansion coefficient, hard texture, good air tightness, wide potential range (about -1 to 1V, relative to saturated calomel electrode). It is formed into an electrode shape such as a cylinder or a disk, and it can also be used as a matrix to form a mercury film glassy carbon electrode and a chemically modified electrode. It is increasingly used in electrochemical experiments or electroanalytical chemistry.
Glassy carbon electrode is one of the most widely used working electrodes. It is a good inert electrode with good conductivity, high hardness, high smoothness, high hydrogen overpotential, wide polarization range, chemical stability, and can be used as inertia. The electrode is directly used for anodic dissolution, voltammetric determination of the cathode and the valence ion, and can also be used as a chemically modified electrode.
