Graphite application

1. The oxidation and reduction method is used to synthesize graphene to prepare graphene modified electrodes to detect the four bases of DNA. Electrochemical research has found that graphene modifiers can achieve the four bases of DNA at the same time. The graphene and carbon nanotubes and β-cyclic paste are compounded. The carbon nanotuba effectively reduces the gathering of graphene. For high -sensitivity testing for berin nucleoside, the modified electrode can be promoted and applied to the determination of other biomolecules.2.

Graphite melting point

Graphite is a kind of homogenous alien in element carbon. Each carbon atom is connected to the other three carbon atoms (multiple hexagonal sixtures with honeycomb -shaped hexagonal) with covalent bonds to form covalent molecules. [1] Because each carbon atom will release an electron, those electrons can move freely, so graphite is a conductive body. Graphite is one of the softest minerals, and its purpose includes a pencil core and lubricant. Carbon is a non -metal element that is located in the second cycle IVA family located in the element cycle table. Latin is Carbonium, which means "coal, charcoal".The melting point of diamond is 3823K, and the melting point of graphite is 3773K. Graphite melting points are lower than diamonds. The melting point of graphite and diamond cannot be considered simply from the aspects of the key energy. If the number of broken keys during melting is ignored, the data obtained is not desirable

Graphite board antioxidant solution increases the period of use

After the formation of graphite board, it must be solved by antioxidantization. Generally, antioxidants are used, which is a thick liquid state. The ingredients are heat -resistant nano -ceramic particles. In the natural environment of air oxidation within 1300 ° C in the application temperature of the graphite board, its antioxidant actual effect is very good. After a variety of specifications of graphite boards with pre -immersed in the antioxidant protective film, its liquid can penetrate into the pores of the graphite board. The sexual protective membrane is exactly the reasonable blocking gas of this layer of protective membrane immediately touched with the graphite plate to produce oxidation reactions. Then it can reasonably resist the air oxidation of the graphite board and increase the use period of graphite board.The period of use of graphite boards has continued to increase, and the service life of traditional raw materials has already increased significantly. It is confirme

Types and prices of scales graphite powder

There are many types of scales graphite powder. Scales graphite powder is a major type of graphite powder. Different types of scale graphite powder. The price of scales graphite powder is different. The scale graphite powder can be divided into high carbon scales graphite powder according to the amount of carbon. Mid -carbon scales graphite and low -carbon scales graphite powder. The higher carbon -containing scale graphite powder, the larger the scale of the scale graphite powder is industrial.The application range of high -carbon scales graphite powder is relatively wide in industry. High -carbon scales graphite powder uses high -quality natural scales graphite as raw materials. The carbon content of high -quality natural scales is very high. Increase the carbon content of scales graphite powder, and under the same factors such as granularity of high -carbon scales graphite powder, the price of high carbon scales graphite powder is higher than the price of carbon scales graphite, lo

What you need to know in the daily use of graphite mold

Due to the special structure of the graphite mold. Therefore, in daily use, these special properties should also be understood by us.1. High temperature resistant type: the melting point of graphite is 3850+50°C, and the boiling point is 4250°C. Even in ultra-high temperature arc burning, the thermal expansion coefficient is very small, and the strength of graphite increases with the increase of temperature. At 2000°C , graphite strength increased - times;2. 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;3. Plasticity: Graphite has good toughness and can be made into very thin sheets;4. Chemical stability: Graphite has good chemical stability at room temperature, and is resistant to acid, alkali and organic solvents;5.
