Here are some of the main reasons why we use graphite in electrodes:
Graphite has a low coefficient of thermal expansion Physical changes in expansion and contraction with changes in temperature are minimal.
Graphite's high thermal conductivity is useful in high-temperature processes, reducing the risk of overheating by dissipating the heat generated, thereby extending electrode life.
High The electrical conductivity of graphite allows an efficient passage of electric current, minimizing power losses and thus ensuring optimal performance.
Graphite is highly chemically inert and does not react easily with most chemicals, even at high temperatures. Therefore, when exposed to corrosive environments, it remains resistant to corrosion and contamination.
Graphite's low density makes it relatively light compared to other conductive materials such as copper, making it easier to handle.
Graphite's mechanical strength and structural integrity at high temperatures allow it to maintain its physical properties over long periods of time.
Graphite is more cost-effective than alternative materials such as copper, making it the preferred choice for high temperature and stress applications.
Easier Machine Graphite can be made into more complex shapes and sizes than other electrode materials, depending on the needs of the process.
With a high melting point graphite can support applications involving extreme temperatures without degradation when temperatures exceed 3,600°C.
What is the price of graphite electrodes?
The cost of graphite electrodes varies widely, depending on factors such as raw material costs, size, grade and market forces. Graphite electrode prices typically range from $2,900 to over $8,000 per ton. Growing demand for electric vehicle batteries and geopolitical factors are increasingly influencing the price of graphite electrodes.
