What is graphite powder? Graphite powder is soft and dark gray; There is a greasy feeling, which can pollute the paper. The hardness is 1 ~ 2, and the hardness can increase to 3 ~ 5 with increased impurities in the vertical direction. The specific gravity is 1.9-2.3. Under the condition of oxygen isolation, its melting point is above 3000℃, one of the most temperature-resistant minerals. At room temperature, the chemical properties of graphite powder are relatively stable, insoluble in water, dilute acid, dilute alkali, and organic solvents; React with oxygen at different temperatures to generate carbon dioxide or carbon monoxide; In halogen, only fluorine can directly react with elemental carbon; Under heating, graphite powder is easily oxidized by acid; At high temperature, it can also react with many metals to form metal carbide, which can be used to smelt metals at high temperature.
Graphite powder is soft, black, and gray, and its melting point is above 3000℃ under oxygen isolation, so it is one of the high-temperature resistant minerals. Graphite powder is stable at room temperature and insoluble in water, dilute acid, and alkali. When oxygen is sufficient, it reacts with oxygen to generate carbon dioxide; when oxygen is insufficient, it reacts with oxygen to generate carbon monoxide; Fluorine can directly react with elemental carbon; At high temperatures, many metal oxides can be reduced by their reducibility, and metals can be smelted, such as iron making.
Main applications of graphite powder Refractory: Graphite and its products have high-temperature resistance and high strength. They are mainly used to make graphite crucibles in the metallurgical industry. Graphite is often used as the protective agent of steel ingots and the lining of metallurgical furnaces in steelmaking. Conductive materials: Used in the electrical industry to make electrodes, brushes, carbon rods, carbon tubes, graphite gaskets, telephone parts, coatings for TV picture tubes, etc. Lubricant: Graphite is often used as a lubricant in the machinery industry. Lubricating oil can't be used at high speed, high temperature, and high pressure, while graphite lubricating material can work at 2000℃ without lubricating oil. High-temperature metallurgical materials: Graphite has reducibility, which can be used to reduce many metal oxides at high temperatures and can be used to smelt metals, such as iron making. Polishing agent and rust inhibitor: Graphite is also a polishing agent and rust inhibitor for glass and paper making in the light industry. It is an indispensable raw material for making pencils, ink, black paint, synthetic diamonds, and diamonds.
Preparation method of graphite powder Graphite powder is the raw ore after blasting, which is sent to a stone crusher through a mine car to be crushed, then floated in a ball mill. The wet graphite material, after flotation, is sent to a ball mill for grinding and selection. The selected wet material is bagged and sent to a rain drier, which becomes a rain-dried material. The rain-dried material is already a finished graphite product. Send the dried material to the drying workshop, dry it and bag it that is ordinary graphite powder. The average carbon content of the finished product is 90%. Uses pencil lead, the battery's graphite electrode, and the cable car's lubricant morphological characteristics. It is a dark gray metallic luster and is an opaque fine scaly solid. Graphite is soft and has a silky feeling. Has excellent electrical conductivity.
Price of graphite powder Graphite powder particle size and purity will affect the product's price, and the purchase volume can also affect the cost of graphite powder. A large amount of large amount will be lower. The price of graphite powder can be found on our company's official website.
