Material characteristics of graphite powder

Graphite powder is a substance that is very sensitive to chemical reactions. In different environments, its resistivity will change, which means its resistance value will change. However, there is one thing that does not change. Graphite powder is one of the good non-metallic conductive substances. As long as the graphite powder is kept uninterrupted in an insulated object, it will also be electrified like a thin wire. However, there is no accurate number for the resistance value, Because the thickness of graphite powder varies, the resistance value of graphite powder will also vary when used 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 after being ignited by an ultra-high temperature arc, the weight loss and thermal expansion coefficient are very small. The strength of graphite increases with te

Graphite electronic effect

The load migration rate of graphene at room temperature is about 15000cm2/(v · s). This value exceeds 10 times the silicon material. More than twice. Under certain conditions such as low temperature, the load migration rate of graphene can even be as high as 250000cm2/(v · s). Unlike many materials, the electronic migration rate of graphene is less affected by temperature changes. At any temperature between 50 and 500K, the electronic migration rate of a single laye

How is high carbon graphite made?

The flotation method for extracting high carbon graphite has the lowest energy consumption, reagent consumption, and cost in mineral purification. This is the biggest benefit of flotation method for purifying high carbon graphite. But when using flotation method to purify graphite, it can only make infinite progress in the grade of graphite. Regarding flake graphite, it is not only impossible to dissociate its complete monomer, but also not beneficial for maintaining the large scale of graphite. To obtain high carbon graphite with a carbon content of over 99%, it is necessary to use chemical methods to purify the graphite.（1） High carbon graphite alkali acid purification method. The carbon content of graphite purified by alkaline acid method can reach over 99%, with characteristics such as low one-time investment, high product grade, and strong process adaptability. It also has strong universality. The purification of non-metallic minerals can accept the advantages of alkaline acid me

The Application of Graphite Processed Parts in Industry

Graphite machined parts are widely used in industry due to the excellent characteristics of artificial graphite materials that cannot be replaced by other metal materials.Graphite machined parts have good conductivity, and with the development of the industry, the size of graphite sheets also changes. In addition, graphite machined parts can also be used as lubricating rings in the electromechanical manufacturing industry as conductive materials.Due to the integration of high-temperature and corrosion resistance of graphite materials into graphite machined parts, many metallurgical furnace linings are made of graphite materials. However, graphite machined parts used as refractory materials must undergo good oxidation resistance treatment when used in oxidizing degassing.Graphite machined parts can be used as corrosion-resistant structural materials. All graphite machined parts need to be impregnated with organic resin to achieve optimal corrosion resistance. Most of them are used as b

Do you know the development history of graphite?

Graphite occupies an important position in the industry, and because of its good performance, graphite is widely used in many industries, and its use effect is good, so it is loved by users. Some basic knowledge of graphite must be known to everyone. The following is the development history of graphite. Presumably very few people know this. So today, let us take a closer look. The following is the introduction made by graphite manufacturers.Graphite is a kind of carbide accidentally discovered in the laboratory by Acheson of the United States in 1891 when he was conducting molten diamond experiments. At that time, it was mistaken for a mixture of diamonds, so it was named emery. The industrial method of smelting graphite, also known as the Acheson furnace, is still in use today. The electric resistance furnace with carbonaceous material as the furnace core generates graphite by heating the mixture of quartz SIO2 and carbon.Several events about graphiteGraphite was first discovered in

How to measure the conductivity of graphite powder

Graphite powder has high conductivity. The conductivity of graphite powder is an important factor in the conductive finished product of graphite powder. There are many factors that affect the conductivity of conductive graphite powder, such as the ratio of graphite powder, external pressure, environmental humidity, humidity, and even light.

Voltammeter method for measuring resistanceSpecific method: Use a precision small range electricity meter or a resistance multimeter to measure and compare the experiment. You can use a small light bulb to measure its conductivity based on its brightness. If the light bulb is brighter, it indicates a smaller resistance.2. Measuring the conductivity of conductive graphite powder through resin methodGo buy some resin for conductive paint, add the same amount of conductive graphite powder, and then apply it on a board to measure its conductivity using a digital
