Properties of graphite

Graphite and its products have excellent properties such as high acid resistance, corrosion resistance, high temperature resistance of 3000℃ and low temperature resistance of -204℃, and are widely used in metallurgy, chemical industry, petrochemical industry, high energy physics, aerospace, electronics, etc. The specific characteristics of graphite are roughly as follows:

1. Super high temperature resistance

The melting point of graphite is 3850±50℃ and the boiling point is 4250℃. Even if it is burned by ultra-high temperature arc, the weight loss is very small and the thermal expansion coefficient is also very small. The strength of graphite increases with the increase of temperature. At 2000℃, the strength of graphite doubles.

2. Graphite products have good thermal conductivity and thermal shock resistance. When used at room temperature, graphite can withstand drastic changes in temperature without being damaged. When the temperature suddenly changes, the volume of graphite does not change much and no cracks will occur.

3. Graphite products have chemical stability and corrosion resistance. Graphite has good chemical stability at room temperature and is not corroded by any strong acid, strong alkali and organic solvent.

4. Graphite products are environmentally friendly and healthy, without radioactive pollution, and resistant to high temperatures. Carbon must undergo a graphitization process of at least a dozen days and nights in a high temperature environment of 2000-3300 degrees to become graphite. Therefore, the toxic and harmful substances in the graphite have long been released, and it is very stable at least within 2000 degrees.

5. Graphite products have good adsorption. The pore structure of carbon makes carbon have good adsorption, so carbon is often used as an adsorption material to absorb moisture, odor, toxic substances, etc.
