Which raw materials are selected for the production of traditional carbon materials

Various metallurgical furnace carbon blocks (such as blast furnace carbon blocks, ferroalloy furnace carbon blocks, calcium carbide furnace carbon blocks, and aluminum electrolysis cell cathode carbon blocks, etc.) are used at a certain high temperature. Therefore, carbon blocks should have high mechanical strength, thermal stability, and corrosion resistance, but the ash content requirements are not too strict. Except for the bottom carbon blocks used in aluminum electrolysis cells, it is not necessary to measure conductivity. The production of carbon blocks mostly uses anthracite as the aggregate and metallurgical coke as the filling material. To improve the thermal conductivity and corrosion resistance of carbon blocks, a certain amount of graphite fragments (or natural graphite) can be added. In order to improve the thermal conductivity and conductivity of carbon blocks, semi graphite carbon blocks can be produced by electrocalcining anthracite.The raw materials used for conductiv

Development of Expandable Graphite

Graphite crystal has a hexagonal network plane layered structure composed of carbon elements. The carbon atoms on the layer plane are bound by strong Covalent bond, while the layers are bound by Van der Waals force force. The binding is very weak, and the distance between layers is large. Therefore, under appropriate conditions, acid, alkali gold, salt and other chemicals can be inserted into the graphite layers, And combine with carbon atoms to form a new chemical phase - Graphite intercalation compound (GIC). When heated to an appropriate temperature, this interlayer compound can instantly and rapidly decompose, producing a large amount of gas, which makes graphite expand along the axis into a new worm like material, namely expanded graphite. This unexpanded Graphite intercalation compound is expandable graphite.Expandable graphite was first discovered by Schaufautl, a German. In 1841, Schaufautl soaked natural graphite in a mixture of concentrated HNO3 and concentrated H2SO4, and t

What are the characteristics of high pure graphite accessories molding graphite?

Graphite is a kind of homogenous alien body for carbon. It is gray -black, opaque and solid. The density is 2.25 grams per cubic centimeter, the melting point is 3652 ° C, and the boiling point is 4827 ° C. The chemical properties are stable, corrosion -resistant, and it is not easy to react with drugs such as acid and alkali. Burning carbon dioxide in oxygen at 687 ° C. Oxidation can be oxidized by strong oxidatives such as concentrated nitrate and potassium hydanol. It can be used as an anti -wear agent and lubricant. High purity graphite is used as a neutron decelerator in the atomic reactor. It can also be used to manufacture crickets, electrodes, brushes, dry batteries, graphite fibers, heat exchangers, coolers, electric arc furnaces, and arc furnaces, and electric arc furnaces, electric arc furnaces, and arc furnaces, and electric arc furnaces. Arc lights, pencils of pencils, etc.Due to its special structure, graphite has the following special nature:(1) High temperature resista

Pulse graphite

As early as the 1930s, China Heilongjiang Jixi Liu Mao and Shandong South Villa Genti Mine began production and processing of pulse graphite. At that time, the mining process was simple, the workers had poor labor conditions, the productivity was extremely low, and the annual output was only thousands of tons. After decades of development, the output of mulberry graphite and carbon products in my country has risen rapidly. From 2004 to 2011, the compound annual growth rate of pulse graphite and carbon products reached 22.12%. In 2011, the output of my country's pulse graphics and carbon products was 25.5617 million tons, an increase of 21.98%year -on -year.Pulse graphite and carbon products have excellent performance, which are increasingly widely used, and production capacity and efficiency are growing rapidly. In 2011, the Chinese pulse graphite and the carbon products industry developed rapidly, and the industry in the industry had high management and control capabilities in cost a

The rise of electric vehicles, the demand for battery materials has increased rapidly

With the improvement of global environmental awareness, electric vehicles have become more and more concerned and favored by people. And one of the most important components of electric vehicles -the battery has therefore become a popular product in the market. However, the popularity of electric vehicles will lead to a significant increase in the demand for battery materials. How big is this market, and which materials will it be the mainstream?First of all, the demand for battery materials is obvious. According to the data of the consulting company Roskill, the size of the global battery raw material market in 2018 is about $ 25 billion, and it is expected to reach $ 70 billion by 2025.
