The raw material of spherical graphite is the high quality natural flake graphite, the advanced processing technology is adopted to modify the surface of graphite, it’s the graphite product which is in different fineness and the elliptical spherical shape. The spherical graphite processing, at first , we get the initial spherical graphite product by by coarse crushing, reconditioning, magnetic separation process from the dry fine graphite ore in graphite workshop, and then we get the spherical graphite (high purity)by high temperature purification in the workshop workshop . Spherical graphite material has good conductivity, high crystallinity, low cost, high theoretical lithium capacity and other characteristics, its charging and discharging potential is low and flat, it’s an important part of anode materials…
Comparative analysis of the advantages and disadvantages of graphite heating and silicon molybdenum rod heating under the condition of long-term working temperature of 1750 degree vacuum The heating temperature is generally higher than the working temperature of 200 DEG C according to the calculation, such as the title, heating the working temperature of 1950 degrees Celsius The maximum working temperature of MoSi2 heating material is 1700 DEG c, Graphite heater (rod, tube, plate) in the absence of air in the working temperature of up to 2500 degrees C. Temperature is not the most important factor, the actual long-term working temperature is about 1600 degrees Contact with oxygen in the air, graphite heater easy oxidation, The workpiece will be placed in…
Graphite can be divided into natural graphite and artificial graphite, the two structures are similar, similar physical and chemical properties, but there is a big difference in use. In many studies, some researchers did not notice the difference between the two and generally referred to as graphite. The result of the confusion between the two has caused a lot of misleading, even the wrong decision-making, resulting in a great waste of resources and economic losses. In this paper, from the perspective of the structure and properties of natural graphite and artificial graphite, the characteristics and differences between them are discussed. 1 Graphite classification and characteristics: 1.1 natural graphite Natural graphite is carbon rich organic matter in the geological environment of…
