Several methods for preparing nano graphite powder using natural graphite

(1) Detonation cracking methodThe detonation cracking method utilizes the properties of graphite that can accommodate foreign negative ion layers to form expandable graphite or lower order GICs, where the ion layer contained is called the insertion layer. In expandable graphite or low order GICs, the insertion layers are regularly arranged in graphite layers. During detonation, the insertion layer rapidly decomposes and releases a large amount of gas, impacting the graphite layers and pushing adjacent graphite layers apart to prepare nano graphite thin sheets. During the detonation process, * * plays two roles simultaneously: firstly, it releases a large amount of heat during the explosion, causing the decomposition of expandable graphite or lower order GICs; The other is to use the shock wave generated during detonation to crush the graphite sheet, achieving the effect of refining the graphite, thereby preparing flake graphite with smaller diameter and very thin thickness.At present,

Battery material, promote renewable energy development

In recent years, with the increasingly serious problems of environmental pollution and energy shortage, renewable energy as a clean, low -carbon, and sustainable development model has gradually been given important strategic significance. Among the applications of renewable energy, batteries as energy storage equipment are also an indispensable part of them. In order to further promote the development of renewable energy, we need to continuously explore new battery materials to improve the power density, cycle life and security of the battery.At present, researchers have proposed many new battery materials, such as lithium ion batteries, sodium ion batteries, zinc air batteries, etc. These battery materials can better meet the needs of energy storage and utilization compared to traditional lead -acid batteries, nickel -metal hydride batteries. Moreover, in the production process, the energy and materials they consume are also greatly reduced, which is more in line with the requirement

Graphite chloride roasting method

The chloride roasting method is to mix graphite with a certain reducing agent to bake at high temperature in specific equipment and atmosphere. The price in the material is transformed into a metal chloride with gas or condensed phase. Purified process.

Is superfine graphite graphite?

Is ultra -fine graphite powder be microflashed?

The size of the material particles determines its name. As you ask questions, micro powder is micron -level powder. In the graphite industry, micro powder generally refers to the diameter of 10 ~ 45 microns. Inside, special graphite powder below 5 microns.Ultra -fine graphite generally refers to graphite with fine particle size. Its particle size is thinner than ordinary microflower graphite. It is generally less than 5um, and the general particle size of microflower graphite is about 10 microns. Qingdao Risheng graphite focuses on ultra -fine graphite production.The specifications of ultra -fine graphite powder are generally between them, mainly used in powder metallurgical destruction agents, graphite, battery negative electrodes, and additives for conductive materials.Graphite powder is divided into: nano graphite powder, colloid graphite powder, scales graphite powder, ultra -fine graphite powder. The number of graphite powder specifications from 50 mesh, and the types of graphite

How to identify the quality of graphite board

The graphite board is not rusty for some manufacturers, but in fact many manufacturers have applied for more than ten years, and they are unclear how to distinguish the quality of graphite boards. This is only a kind of summary of the product, which is very vague.Speaking of how to distinguish the advantages and disadvantages of graphite boards, there is only one key, which is the relative density. The following discusses the necessity of using the Moore quality formula from many levels.The battery electrolyte is very prone to infiltration, resulting in the oxidation of the graphite board air, which is greatly shortened by the use period. The density is high, and the cost of application is increased, so it is important to choose a suitable graphite board manufacturer.2. In the field of resistance, the key to the graphite board is used to pad the method, which has a moisturizing effect. The relative density of the graphite board here is greatly displayed. Very easy to fall, the surface

Key elements that endanger the sales of graphite anode board

The key element of the sales of graphite anode plates Graphite anode board itself is a kind of conductive material. As a conductive, the name is the anode oxidation. Graphite anode plate is a type of electrolytic material. Compared with other anode oxide materials, there is no doubt its advantages. Simply speaking, the application field is wide, organic chemistry is stable, heat -resistant and heat transfer performance is better!Graphite anode boards occupy a large part of the annual sales of my company, which shows that the corporate graphite anode board products have a certain degree of recognition in the sales market. In addition, the sales of graphite anode oxide products have gradually soared.Each product is an industry that it uses, except for the graphite anode plate! It is necessary to improve the characteristics of the graphite anode plate itself and the scope of use. Graphite anode specifications in the field of electrolytic aluminum industry with large amounts and electropl

Many new main uses of graphite have already been developed and designed

Many new main uses of graphite have long been developed and designed with the development trend of scientific and technological progress. Graphite has many new main uses. High -purity graphite products are used for high -purity metallurgical industry, electronics industry, Chinese nuclear industry and mold processing; general graphite products can be used as a wall -building raw material for mining with aluminum electrolytic grooves, non -metallurgical tunnel furnaces, and non -ferrous metal furnaces. Calcium residual raw materials can be used as carbon increases for ironmaking industry. There are many types of carbon quality raw materials used to seepage nitrogen, including artificial synthesis of graphite, petroleum coke, casting focus, and pure natural graphite.Graphite products are at least within 2000 degrees.
