What is high-purity graphite powder? Graphite powder is contains a small number of s, p, fe, mn. High-purity graphite powder has the advantages of high-temperature resistance, corrosion resistance, and lubricity. Graphite powder is one of the important raw materials for the production of pencil lead; It is also the raw material for making refractory materials and coatings; It is also an important carbon material, which is widely used in the metallurgical industry as a deoxidizer for steelmaking and manufacturing artificial diamond and refractory materials; In addition, it is also used as an additive for paint fillers and abrasives. In the chemical industry, it is mainly used to purify metals or alloys and as a protective gas in preparing hydrofluoric acid and other strong corrosive substances.
Material Characteristics of High-purity graphite powder High-purity graphite powder is one of the good non-metallic conductive materials. As long as the graphite powder is kept uninterrupted in the insulating object, it will also be energized like a thin wire. However, there is no accurate value for the resistance value because the thickness of graphite powder is different. The resistance value of graphite powder will be different when used in different materials and environments. Because of its special structure, graphite has the following special properties: (1) Chemical stability: Graphite has good chemical stability at room temperature and can resist acid, alkali, and organic solvent corrosion (2) Plasticity: Graphite has good toughness and can be connected into very thin sheets (3) Thermal shock resistance: when graphite is used at room temperature, it can withstand the drastic change in temperature without damage. When the temperature changes suddenly, the volume of graphite changes little, and no cracks will occur.
Application of High-purity graphite powder 1. As refractory materials: Graphite and its products have the properties of high-temperature resistance and high strength. They are mainly used to make graphite crucibles in the metallurgical industry. In steelmaking, graphite is commonly used as the protective agent for steel ingots and the lining of metallurgical furnaces 2. As conductive material: used in the electrical industry to manufacture the positive pole of electrodes, brushes, carbon rods, carbon tubes, mercury positive current devices, graphite gaskets, telephone parts, coating of TV picture tubes, etc 3. As wear-resistant lubricating material: Graphite is often used as a lubricant in the machinery industry. The lubricating oil cannot be used under high speed, high temperature, and high-pressure conditions. Graphite wear-resistant materials can work at a high sliding speed at a temperature of (I) 200~2000 ℃ without lubricating oil. Many equipments transporting corrosive media widely use graphite materials to make piston cups, sealing rings, and bearings; Graphite emulsion is also a good lubricant for many metal works (wire drawing and tube drawing).
Price of high-purity graphite powder High-purity graphite powder particle size and purity will affect the product's price, and the purchase volume can also affect the cost of high-purity graphite powder. A large amount of large amount will be lower. The price of high-purity graphite powder can be found on our company's official website.
