Glassy carbon, also known as glass carbon, is a non-crystalline carbon material with a glass-like appearance, which is obtained by slowly heating polyacrylonitrile resin or phenolic resin in an inert atmosphere at high temperature (up to 1800°C). It is a suitable electronic conductor material for electrodes and is widely used in table tennis blades.
The advantages of glassy carbon electrodes are good conductivity, high chemical stability, low thermal expansion coefficient, strong hardness, good airtightness, and a wide potential range (approximately -1 to 1V, relative to the saturated calomel electrode). They can be made into cylindrical, disc-shaped, and other electrode shapes. When used as substrates, they can also be made into mercury film glassy carbon electrodes and chemically modified electrodes. They are increasingly used in electrochemical experiments or electroanalytical chemistry.
Electrode characteristics: Glassy carbon electrodes are widely used working electrodes. They are good inert electrodes with good conductivity, high hardness, high smoothness, high hydrogen overpotential, wide polarization range, chemical stability, and can be directly used as inert electrodes for anodic dissolution, voltammetric determination of cathodes and redox ions, and as chemically modified electrodes.
