You can Google the graphite electrode . Simply put, the graphite electrode used today can be understood as a resistive semiconductor, and its resistance is very small. However, since people make some new materials, they basically have to sacrifice the performance of electrode materials to make various electrodes. Such as triode, and so on. Therefore, the performance of graphite electrodes also affects its price to a certain extent. But in general, the price is determined by the performance.

The specific performance cannot be seen, but there are two kinds of materials used in general motors: 1, high conductivity and low corrosion resistance.  2. Low electrical conductivity and high corrosion resistance.

Specific volume value, graphite is one of the pressure vessel grade materials. Specific heat capacity, graphite is one of the capacity container grade materials.

The key depends on how you want to use it. The logic circuit of the three-phase combination is a capacitor, and the high-power electronic circuit is a three-phase capacitor.

Graphite alloy is a chemical product, which is used to make oxides with particularly good corrosion resistance. And the graphite on the market is graphite electrodes, not graphite raw materials (also mixed with other materials). In terms of characteristics, graphite is highly conductive, high rotational resistance, poor electrical conductivity, compressible and cladding, etc. Therefore, the comparison of price and purity should be related to the performance of the graphite electrode material itself. But according to general industrial needs, no one cares about impure graphite or silicon-based silicon paste. So it can flow down, because the resistance is high and the efficiency is low, so there is no need to ensure sufficient quality.

Graphite electrodes are vacuum clad. The usage in the chemical industry is to put the silicon slag in the solution, and after it is reduced to graphite, the electrode surface is treated on the metal plate.
