Pyrolytic Graphite Electrode

Pyrolytic graphite electrode shapes are diverse, flexible size, excellent purity. Whether it’s small or grand, it can be based on your specific needs. Through professional customization process, it can perfectly fit your project requirements. The carbon content of the graphite electrode is generally as high as 98% or high. And it is a well-deserved model of high-purity electrode materials.

Advantages of pyrolytic graphite electrodes

• High temperature stability: Pyrolytic graphite electrodes can withstand extremely high temperatures. And it still maintains structural stability under high temperature environments of more than 3000 ° C, without softening and melting. This allows it to work stably in high-temperature melting, high-temperature synthesis and other processes. Such as in the smelting process of special metals. This can withstand high temperatures for a long time and continue to play the role of electrodes.

• Excellent electrical conductivity: With good electrical conductivity, it can efficiently conduct current. In electrochemical applications, it can effectively reduce resistance loss, improve energy efficiency. In large-scale electrolytic industries, such as electrolytic aluminum production, its excellent electrical conductivity helps to reduce production costs and increase production speed.

• Chemical tolerance: It has a strong chemical inertia, acid, alkali, organic solvents and other chemical substances. It has a high degree of tolerance, not easy to chemical reaction and corrosion. In the complex chemical environment in the chemical field, such as the presence of various electrolytes and corrosive gases, it can run stably for a long time. This reduces the frequency of electrode replacement and maintenance costs.

• Low expansion coefficient: The thermal expansion coefficient of the pyrolytic graphite electrode is very low. And its size changes slightly when the temperature changes. This feature is particularly important in high-precision machining and experimental processes. Such as semiconductor manufacturing. This ensures the dimensional accuracy of electrodes at different process temperatures and ensures the stability of product quality.

Applications of  pyrolytic graphite electrode

The surface of the pyrolytic graphite electrode can be modified to selectively detect ions. For example, when detecting heavy metal ions, chemically modified electrodes produce specific reactions with heavy metal ions. And ion concentrations are determined according to changes in electrochemical signals. It can also detect organic matter. Such as the detection of glucose and other biological small components, fixed on the electrode surface of the glucose oxidase and other biological enzymes. It uses the enzyme and glucose specific reaction generated by the electrical signal changes for quantitative detection.

In the field of electrochemical research, the pyrolytic graphite electrode has good conductivity and stability. And we can use it to study the charge transfer process on the electrode surface, substance adsorption and desorption process and other kinetic problems. This helps to deeply understand the mechanism of electrochemical reaction. And it provides theoretical support for the design of high-performance electrochemical devices. At the same time, we can also use it as a catalyst carrier, load different catalysts to study the impact of electrocatalytic reactions. Such as oxygen reduction reaction, hydrogen evolution reaction, etc.. Therefore we can explore efficient electrocatalytic materials and reaction systems. And this also promotes the progress of fuel cells, electrolytic water and other technologies.

In sensor applications, pyrolytic graphite electrodes can respond to specific gases. For example, sensitive materials such as metal oxides are modified on the electrode surface to detect gases such as oxygen, hydrogen, and carbon monoxide. It can also make biosensors for detecting substances or biological activity in living organisms. For example, combine it with enzymes, antibodies, nucleic acids and other biometric elements. Then it can quickly and sensitively detect blood sugar, blood lipids, pathogens and so on.
