Introduction to the use of expansion graphite

The expansion graphite was discovered in the early 1960s. Many countries like to use it to study, so that many unexpected results can be achieved. The so -called expansion can be increased by more? That's right, more than double or even double! It is new carbon material! Many people don't know much about expansion graphite!Graphite crystals are two -way large -molecular layer -like structures. The C atom in each plane is combined with the C -C co -price bond, and the layer is combined with weaker Van Dehua.The layered structure of graphite is very typical. Each layer is a carbon atomic layer. The carbon atom in the layer is a strong covalent bond with SP2 hybrid orbit, that is, 1 2S electronics and 2 2P electronic hybridization, etc. The hybrid track of the price is located on the same plane and forms σ bonds each other, while the two unsteady 2P electrons are perpendicular to the plane to form a two -key π. This layered structure of graphite makes a certain gap between layers. Theref

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

The Price of Spherical Graphite and Its Use

The price of spherical graphite is related to the use of graphite, which is widely used in many industrial fields.1. The price of spherical graphite is related to the use of graphite for refractory purposes, including bricks, crucible disasters, continuous casting powder, mold cores, molds, and refractory material detergents. Two important changes in the refractory industry are the widespread use of magnesium carbon bricks for steelmaking furnace lining and the application of aluminum carbon bricks in continuous casting. Graphite refractory materials, steel and other industries are closely related, and magnesium's MgO-C in the world has been widely used for steelmaking and has become a traditional use of graphite. Aluminum carbon bricks are mainly used for continuous casting of carbon refractory materials, and for flat protection of slabs such as pipelines and underwater nozzles. Molded refractory crucibles and related products produced from graphite crucibles and related products, su

Graphite flotation method

Floating is a commonly used and important mineral method. Graphite has good natural floating. Basically, all graphite can be purified by floating methods. In order to protect graphite scales, most of the graphite flotation uses multiple sections of processes. Graphite flotation collecting agents are generally used for kerosene, with a dosage of 100 to 200g/t. The foaming agent is generally used with pine or butad ether, and the amount is 50 to 250g/t.

Introduce the knowledge and application of graphite chemistry

Graphite has a wide range of applications, and many products in our lives are inseparable from its role. We have also learned some basic knowledge of graphite before, and have a simple understanding of its application fields. We know very little about graphite. Only with more knowledge about the product can we apply it better in the future. The following is the graphite knowledge introduced by graphite manufacturers.Due to its stable chemical properties, high thermal conductivity, low thermal expansion coefficient, and good wear resistance, graphite has many other uses besides abrasives. It is an excellent deoxidizer and can accelerate refining. The tapping speed is fast, the chemical composition is easy to control, and the quality of the steel is improved. Graphite powder is coated on the inner wall of the turbine impeller or cylinder through a special process, which can improve its wear resistance and prolong its service life.

Silicon fossil system

Chemical gas deposition (CVD) method) methodSilicon and carbon -containing gases have a heat decomposition through high -temperature graphite matrix, and SIC is deposited on the surface of the graphite matrix. The raw materials are trichloronetas (CH3SIC3), silicon chloride, hydrogen, silicon steam, etc. The deposition temperature range is wide, from 1175 ° C to 1775 ° C. The SIC layer generated by this method is very dense, the thickness is uniform, and the general thickness is about 0.1 to 0.3mm. However, the combination of SIC and graphite matrix is a combination of pure machinery, and the combination force is weak. When the temperature changes, the SIC layer is prone to cracking and peeling.Chemical Qi Evidence Method (CVR)The raw materials are coke powder and excessive quartz sand or non -fixed silicon powder.
