High-purity graphite production process , we may not be particularly familiar with, in life, it is basically not get our special attention, there are not many people to understand. High-purity graphite is a high-purity metal and related semiconductors that use graphite in production. In order to further increase the purity of metal materials and semiconductors, and reduce the number of other materials, high carbon content must be required, and it must be low. High-purity graphite impurities can meet the requirements. Next, I will give you some popular high-purity graphite production process and related knowledge.
High purity graphite
Properties: Scales are complete in crystallization, thin and good toughness, excellent physical and chemical properties, good thermal conductivity, temperature resistance, self-lubricating, conductivity, thermal shock resistance, corrosion resistance and other properties.

Non-metallic materials. For the manufacture of electric heating elements, structural casting molds, smelting boats for high purity metal boats, heaters for single crystal furnaces, EDM graphite, sintering dies, electron tube anodes, metal coating, graphite crucibles for semiconductor technology, Emission electron tube, thyristor and mercury arc rectifier graphite anode, grid and so on.
Features and applications: High-purity graphite has the characteristics of high strength, high density, high purity, high chemical stability, compact and uniform structure, high temperature resistance, high conductivity, good wear resistance, self lubrication, easy processing, etc. It is widely used in metallurgy. , chemical, aerospace, electronics, machinery, nuclear energy and other industrial fields. In particular, large-size, high-quality, high-purity graphite, as a substitute material, has a wide application space in high-tech and new technology fields, and has a wide range of application prospects.
High purity graphite use
It is widely used in advanced refractories and coatings for the metallurgical industry, stabilizers for pyrotechnic materials in the military industry, pencil cores for light industry, carbon brushes for the electrical industry, electrodes for the battery industry, and catalyst additives for the fertilizer industry. After high-purity graphite deep processing, it can produce graphite milk, graphite sealing materials and composite materials, graphite products, graphite anti-wear additives and other high-tech products, and become important non-metallic mineral raw materials for various industrial sectors.

High purity graphite production process
Raw material control impurity content
When manufacturers produce high-purity graphite, they must strictly control the content of high-purity graphite impurities. The raw materials with low ash content are the objects of choice when processing high-purity graphite. Also note the increase in impurities. This laid a good foundation for the subsequent production of high-purity graphite.
High temperature removal of impurities
Just now, when it comes to controlling the increase of impurity content, high-temperature control of impurities can be used. Under high temperature processing, the oxides of many impurities in high-purity graphite will be continuously evaporated and decomposed. If the temperature is higher, the impurities in high-purity graphite will be excluded. In contrast, the purity of high-purity graphite has also increased. When the merchants produce ordinary high-purity graphite, it is hard to imagine that the high temperature of the core is actually at 2300 degrees. At this time, the content of impurities is about 0.1% to 0.3%. If the temperature of the furnace core is increased again, the impurities in the high-purity graphite will be greatly reduced when it reaches 2500 to 3000 degrees.
Increase the density of current extraction of high purity graphite
When high-purity graphite reaches a high temperature of 3,000 degrees, some impurities cannot be removed. Graphite has taken a new approach to reduce the core temperature and directly increase the current density to extract high-purity graphite. As a result, the output of the graphite furnace core is reduced, but as the amount of current increases, the power consumption also increases.
The last purification of high purity graphite
In the final purification process, a necessary process is to pass in the purge gas, such as some Freon and chlorine, so that the solid impurities in the high-purity graphite can be quickly decomposed. In order to avoid the reverse diffusion of impurities, putting in some nitrogen can clean the remaining gas clean.
Editor's summary: With the continuous development of science and technology, people have also developed many new uses for graphite. Flexible graphite products. Flexible graphite, also known as expanded graphite, is a new graphite product developed in the age. The United States has succeeded in researching flexible graphite sealing materials and solved the leakage problem of atomic energy valves. Subsequently, Germany, Japan, and France began to develop and produce. In addition to the properties of natural graphite, this product also has special flexibility and elasticity. Therefore, it is an ideal sealing material. Widely used in petrochemical, atomic energy and other industrial fields. The international market demand has increased year by year.
