What is graphite powder?
Graphite powderis a kind of mineral powder, the main component is carbon, it is soft, black and gray; it has a greasy feeling and can pollute the paper. The hardness is 1 to 2, and the hardness can be increased to 3 to 5 with the increase of impurities in the vertical direction. The specific gravity is 1.9 to 2.3. Under the condition of isolating oxygen, its melting point is above 3000 ℃, which is one of the most temperature-resistant minerals. The chemical properties of graphite powder at room temperature are relatively stable, insoluble in water, dilute acid, dilute alkali and organic solvent; the material has high temperature resistance and electrical conductivity, and can be used as refractory material, conductive material, wear-resistant lubricating material.
What are the material properties of graphite powder?
Graphite powder is a substance with very sensitive chemical reaction. Its resistivity will change in different environments, that is, its resistance value will change, but one thing will not change. Graphite powder is a good non-metallic conductive substance. One, as long as the graphite powder is kept uninterrupted in an insulating object, it will also be energized like a thin wire. However, the resistance value is not an accurate number, because the thickness of the graphite powder is different. The resistance value of graphite powder will be different in different materials and environments. Due to its special structure, graphite has the following special properties:
1) High temperature resistant type: The melting point of graphite is 3850±50℃, and the boiling point is 4250℃. Even if it is burned by an 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 increasing temperature, and at 2000°C, the strength of graphite doubles.
2) Electrical and thermal conductivity: The electrical conductivity of graphite is one hundred times higher than that of ordinary non-metallic minerals. The thermal conductivity exceeds that of metal materials such as steel, iron, and lead. The thermal conductivity decreases with increasing temperature, and even at extremely high temperatures, graphite acts as a thermal insulator.
3) Lubricity: The lubricating performance of graphite depends on the size of the graphite flakes. The larger the flakes, the smaller the friction coefficient and the better the lubricating performance.
4) Chemical stability: Graphite has good chemical stability at room temperature and is resistant to acid, alkali and organic solvent corrosion.
5) Plasticity: Graphite has good toughness and can be connected into very thin sheets.
6) Thermal shock resistance: When graphite is used at room temperature, it can withstand severe changes in temperature without damage. When the temperature changes suddenly, the volume of graphite changes little and no cracks occur.
What are the development prospect of graphite powder?
It is expected that in the next ten years, as long as the entire market is sufficient to support and the mining and expansion are successful, the production capacity of graphite powder will continue to grow. The new graphite production capacity will make up for the current 100,000 tons of flake graphite production capacity lost due to engineering mistakes. According to industry analysts, global graphite product research and development will be carried out in ten areas. At the same time, as the world's largest graphite producer established by the former State Building Materials Bureau, China's output accounts for 40% to 50% of the world's total output. India, the world's second producer, has accounted for about 15% of graphite production in the past decade. Other producing countries are Brazil (7%), Mexico (6%) and North Korea (6%). The total graphite output of the above five countries accounts for more than 75% of the world's total output.
If the world graphite market environment continues to develop in a favorable direction in the future, graphite production will increase, especially in Brazil, Canada, China, India and Mexico. The total is expected to increase by 120,000 tons. Under the guidance of the direction of graphite deep processing proposed in the "Tenth Five-Year Plan", the key graphite deep processing products developed in my country in the next five years are special-shaped carbon, fluorinated graphite, silicon-infiltrated graphite, kinescope graphite emulsion, lithium ion battery, carbon material, fuel Battery carbon materials, etc.
In addition, there is still a large gap in the production of graphite deep-processed products in my country, and the development work has great achievements. For example, there are 1,000 nuclear power plants in the world, and my country currently has only three, while the state plans to build 23 nuclear power plants. The nuclear pure graphite used in these plants is basically all imported.
At present, with the globalization of economic development, the research and development of global graphite industry products will be carried out in ten fields:
1. High-performance seals and products, the world has a transaction volume of 10 billion US dollars, and the highest-grade graphite products for nuclear reaction are 1.2 million US dollars / ton. There are four key technologies in this product, inserting technology, puffing sulfur technology, composite reinforcement technology, and forming technology.
2. High-performance conductive materials, one is to make interlayer compounds; the second is high-performance stability; the third is process repairability.
3. Battery material.
4. Environmental protection materials.
5. Biological materials.
6. Sound insulation and heat insulation materials.
7. Protective safety materials.
8. Shielding material.
9, arts and crafts materials.
10. Catalyst.
