Knowledge About High Purity Graphite Powder Properties

admin / 2023-08-09 / no Comments

Graphite powder It's a type of mineral powder. The main component is carbon-simple substance. It has a dark grey color. Graphite is a powder with high temperature resistance, electrical conductivity. It's used in refractory material, conductive material, and wear resistant lubricating materials.

High Purity and Graphite powder Properties

Graphite powder is easier to oxidize by acid under heating. It is easier for graphite to oxidize by acid when heated. However, at high temperatures it can react with metals and form metal carbides which can melt metals.

Graphite Powder is a chemically sensitive substance. Its resistance will change with different environments. Graphite Powder is a very good non-metallic conductive substance. As long the graphite is not interrupted in the insulating material, it will energize like a thin cable.

The special properties of graphite are due to the special structure of its powder:

1) Type high temperature resistant: The melting and boiling points of graphite are 3850+-50°C, respectively. Weight loss and thermal expansion coefficient will be very small even if graphite is burnt by an ultra-high temperature arc. With increasing temperature, the strength of powdered graphite increases. At 2000degC the strength of graphite powder doubles.

2) Electrical conductivity and thermal conductivity. The electrical conductivity in graphite is 100 times higher than the conductivity of non-metallic mineral materials. The thermal conductivity of graphite is greater than metals like steel, iron and lead. The thermal conductivity drops with temperature. Even at very high temperatures, graphite is an insulator.

3) Lubricity: The lubricating properties of graphite powder depend on the size graphite flakes. The smaller the flakes are, the lower the friction coefficient is and the more lubricating the powder will be.

4) Chemical stability Graphite is chemically stable at room temperatures and resistant to acids, alkalis, and organic solvent corrosion.

5) Plasticity Graphite is a tough powder that can be shaped into thin flakes.

6) Thermal Shock Resistance: Graphite Powder can withstand dramatic changes in temperature when used at normal room temperature. When temperature suddenly changes, graphite's volume does not change and there are no cracks.

To create fillers and performance enhancers of rubber, plastics, or other composite materials, to improve wear resistance, pressure resistance, conductivity, or conductivity.
Natural graphite can be used to mark pencils, motor brushes, zinc-carbon batteries and other professional applications.
An innovative application for nuclear-grade graphite are the ultra-high temperature reactor (UHTR), as well as the next generation nuclear power plants (NGNP).

What is graphite?
Graphite is a form of graphite, but it's only a type of graphite.
Graphite, an allotrope for carbon, is called graphite. It is opaque solid and grayish black. It is oily and can pollute paper.
Its hardness is between 1-2 and 3-5 depending on the amount of impurities that are vertically oriented. The specific gravity ranges from 1.9 to2.3. The specific surface area of the mineral is limited to 1-20m2/g. Under the condition of oxygen isolation, its melting point is above 3000, so it is one of the most temperature-resistant minerals. It can conduct heat and electricity.
Chemical stability, corrosion resistance. It is not easy to react against acid, alkali, or other agents. Graphite reacts with oxygen to produce carbon dioxide. Strong oxidants, such as potassium permanganate and concentrated nitric Acid, can oxidize graphite.
Natural graphite is not pure, so it often contains impurities, such as SiO2, Al2O3, FO, CaO or P2O5, and CuO. These impurities can often be found in the form quartz, pyrite or carbonate as well as other minerals. Water, asphalt, CO2, H2, Ch4, N2 or other gas parts are also available. The analysis of graphite requires that, in addition to determining the fixed carbon content, volatile matter and Ash must be done simultaneously.

Is graphite dust toxic?
Excessive intake of graphite can cause respiratory problems. There have been documented health effects such as pulmonary fibrosis or pneumoconiosis. This is an occupational lung disease. Workers' lung function and cardiovascular system may also be affected.

What can you substitute for graphite powder in
Graphite powder can be used as a dry lubricant. However, it can corrode aluminum when there is moisture. Graphite can now be replaced by molybdenum-dioxide MoS2 powder.

High Purity Powder Graphite
You can use graphite powder as a refractory material, conductive material, casting, molding, and high-temperature high-temperature metal materials. It can also be used for polishing agents, pigments, and boiler scaling.
1, as refractory substances: graphite or its products with higher temperature resistance, high strengths properties, in metallurgical industries is mainly used for the manufacture of graphite Crucible, in steelmaking graphite can be used as a protective agents for ingot, metallurgy lining.
2, as conductive materials: used in the electric industry to make electrodes and graphite gaskets. Telephone parts, TV picture tube coatings, and other electrical components.
3: Graphite is often used as a grease in the machinery sector. Lubricating oil is often not suitable for use under high speed, high temperature, and high-pressure conditions. However, graphite materials are capable of sliding at 2002000 degrees Fahrenheit, with no lubricating oils. In many equipment used for conveying corrosive materials, graphite bearings are common. They don't require any lubricating oil for running. Graphite is a good lubricant when processing metals (wire drawing, tubing).
4. casting, aluminum casting molding, and high temperature metallurgical material: Due to graphite's small thermal expansion coefficient, and its ability to change the thermal shock, can you use it as a glass mould? After using graphite dark metal casting dimension conforms with the requirements, the surface shines brightly and produces high yield without any processing. This allows you to save large amounts of metal.
5 graphite can also prevent boiler scale. The relevant unit testing shows that the amount added to water (45 grams per ton) can prevent boiler surfaces from scaling. Graphite can also be coated on metal chimneys or roofs.
6. Graphite can be used to polish and pigment.
