Graphite electrodes: from basics to applications
1. Basic characteristics of graphite electrodes
Graphite electrodes, with their unique physical and chemical properties, play a vital role in modern industry. As an important conductive material, graphite electrode has the characteristics of high electrical conductivity, high thermal stability, strong chemical stability and easy processing.

First, graphite electrodes have high electrical conductivity. Graphite is a good conductor, its electrical conductivity is second only to metals, and in some aspects it is even better than some metals. This characteristic makes graphite electrodes widely used in electric power industry, electronic industry and other fields.
Secondly, graphite electrodes have high thermal stability. Graphite has an extremely high melting point and can maintain the stability of its structure and performance in high-temperature or even ultra-high-temperature environments. This makes graphite electrodes widely used in high-temperature industries such as high-temperature metallurgy and glass manufacturing.
Furthermore, graphite electrodes have strong chemical stability. Graphite has good corrosion resistance to most acids, alkalis and organic solvents, which makes graphite electrodes widely used in chemical industry, environmental protection industry and other fields.
Finally, graphite electrodes are easy to process. Graphite is soft and easy to cut, carve and shape, which makes graphite electrodes highly flexible and convenient in the manufacturing process.
2. Manufacturing process of graphite electrodes
The manufacturing process of graphite electrodes mainly includes the steps of raw material selection, batching, kneading, molding, roasting and graphitization.
First of all, raw material selection is the first step in graphite electrode manufacturing. The raw materials of graphite electrodes are mainly petroleum coke and pitch coke. The selection of these raw materials directly affects the performance and quality of graphite electrodes.
Secondly, ingredients are the mixing of selected raw materials in certain proportions to achieve the desired performance. The batching process requires precise measurement and control to ensure the stable performance of the graphite electrode.
Then, kneading is to mix and knead the prepared raw materials to form a uniform mixture. The kneading process has an important impact on the uniformity and density of graphite electrodes.
Next, forming involves pressing the kneaded materials to form the preliminary shape of the graphite electrode. The molding process requires precise control of pressure and temperature to ensure the shape and dimensional accuracy of the graphite electrode.
Then, baking is to heat treat the shaped graphite electrode at high temperature to make its structure more stable. The roasting process requires precise control of temperature and time to ensure the performance and quality of graphite electrodes.
Finally, graphitization is to graphitize the calcined graphite electrode at high temperature to achieve a higher degree of graphitization and better performance. The graphitization process requires extremely high temperatures and long-term processing, and is the most critical step in graphite electrode manufacturing.
