Carbon vs Graphite Rod

Carbon Graphite Products

Differences in raw materials and properties

Graphite rods are made of natural graphite through high-temperature baking and high-pressure processing. Its main component is graphite, so graphite rods have the characteristics of easy conductivity, wear resistance, and high-temperature stability.

Carbon rods are made of a mixture of various carbonaceous materials. Their conductivity and thermal stability are not as good as graphite rods, but carbon rods have certain chemical stability and mechanical strength.

Differences in use

Because graphite rods have high conductivity and stability, they are widely used in the manufacture of carbon brushes and electrodes with high conductivity requirements. In the manufacturing process of graphite rods, ceramics or metals can also be sprayed on their surface to improve their surface hardness and wear resistance. Carbon rods are usually used in ordinary batteries, dry batteries, automatic igniters, electric furnaces, etc.

Related applications of graphite rods and carbon rods

1. Application of graphite rods

(1) Polymer batteries: Graphite rods can be used as conductive materials for battery electrodes and are used to produce secondary lithium-ion batteries and polymer batteries, etc.
(2) Waste gas treatment: They can be used as process materials for gas treatment devices to purify waste gas;
(3) Conductive materials: They can be used to manufacture conductive materials, such as electromagnetic wires, IGBT chips, capacitors, etc.

2. Application of carbon rods

(1) Match heads: When producing match heads, phospholipids and wood are needed, and some powders and carbon powders are added to react with red phosphorus. The added carbon powder is the carbon rod;
(2) Dry cell batteries: Carbon rods are one of the main components of dry cell batteries. They can be used as the basis of electrolyte and electrode materials;
(3) Electric furnaces: The electrodes in electric furnaces are made of carbon rods. They are usually used in petrochemical and aluminum industries, etc.

In summary

although graphite rods and carbon rods are both conductive materials, there are some differences in their raw materials, processing and use. Graphite rods have high conductivity, high temperature stability and wear resistance. They have a wide range of applications, including polymer batteries, waste gas treatment, conductive materials, etc. Carbon rods are usually used in dry batteries, match heads, electric furnaces, etc. For different needs, you can choose the appropriate material according to the actual situation.
