Cast iron graphite

The formation process of graphite in cast iron is called graphization process. The basic process formed by cast iron tissue is the formation of graphite in cast iron.The graphite type and size of the gray cast iron depends on the graphite branches and growth rate in the common crystal group. When the common crystal group stops growing, the graphite will stop. They are separated and not connected. Using scanning electron microscope to observe the complete graphite in the common crystal groupThe three -dimensional form indicates that they are connected to each other. Only on the gold phase grinding surface is isolated.The national standard has the following divisions of the graphics of cast iron graphite: type A fine sheet, B -shaped flower shape, C -shaped thick blockbuster, D -shaped dot, E has directional points, f spider -like or planetary. The longest (100 times, greater than 100mm is 100mm. It is called 100mm long). The shortest graphite is the shortest (100 times at 100 times, le

The key role of graphite in battery technology

Application of expanded graphite

The application of scales graphite in the casting industry

Scales graphite is widely used in industry, especially the casting industry. In the production process of the casting industry, the casting process is carried out at high temperature environments. In order to prevent castings from deforming or broken at high temperatures, special casting scales need to be added to add cast materials and add casting materials. After the scale graphite, it can resist high temperature to ensure the quality of the casting. The following editor of graphite manufacturers will introduce the important application of scales graphite in the casting industry:There are many specifications for casting scales for castings, 600 meters ~ 800 mesh, 1200 mesh and other specifications for casting dedicated graphite. In different casting production fields, special casting scales of different mesters need to be used. Graphite helps the product to complete faster and better, and improve the quality of the casting products. Therefore, the scale graphite of the cast plant is

Thermal conductivity of polycrystalline graphite

The so-called carbon materials such as artificial graphite molded products are polycrystalline materials with extremely complex structures, and the basic structure of graphite crystallization has strong anisotropy. Therefore, the macroscopic thermal conductivity of carbon materials, apart from relying on empirical data, is almost unpredictable. The factors that have a significant impact on thermal conductivity include:(1) The differences in the basic properties of the initial raw materials;(2) The manufacturing process - macroscopic anisotropy;(3) Heat treatment temperature - the growth degree of graphite microcrystals;(4) Apparent density, distribution of holes, etc.

What are the reasons for the low initial efficiency of lithium carbide graphite negative electrodes

1. Low specific surface area: As you mentioned, the specific surface area of waste graphite is usually low, which leads to a decrease in the contact area between the electrolyte and graphite, affecting ion insertion and extraction during the initial charge and discharge process, thereby reducing the initial Coulombic efficiency. Compaction and coating treatment can increas
