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. Chemical reactions occur when heated to 2000 ° C to generate SIO vapor. SIO steam and carbon -based reactions generate SIC. There is no obvious interface between SIC layers

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 Properties of Graphite and Its Application in Smelting

Graphite undergoes special forming methods to achieve its industrial application characteristics, namely special graphite. The three high graphite is commonly known as the three high graphite in the industry, but not all three high graphite is isostatic pressure graphite. In addition, there are materials such as molded and extruded graphite, which, due to their special structure, have high temperature resistance, conductivity, thermal conductivity, lubrication, chemical stability, and plasticity Characteristics such as thermal shock resistance.The application of graphite in the metallurgical industry is due to its high temperature resistance, thermal conductivity, stable chemical properties, and thermal shock resistance. In the metallurgical industry, graphite is mainly used as a refractory material. We are familiar with graphite crucibles, refractory bricks, and casting molds in the metallurgical industry. Graphite products are closely related to the smelting industry, and in the ste

graphite expansion graphite environmental materials

The effect of expanding graphite on water pollution has a large number of research results. In terms of governing oil and organic pollution in the control of water bodies, expansion graphite is far more effective and economical than ordinary activated carbon now. But expansion graphite is inconvenient to transport and needs to be prepared at the application site. The preparation, use, recycling, and regeneration of expansion graphite environmental protection materia

The best way to improve the life of graphite boards to use antioxidant solution

The best way to improve the life of the graphite board is the success of anti -oxidation solution with the development of graphite boards. After delivery and use in many industries, there will still be more and more technical advantages and characteristics in many levels. Among them, the continuous improvement of processing work capacity will still be unusual in the advantages and performance levels of its talents. In more cases, they all feel that their technical standards will still be higher and higher. The selection generated will still have a difference.Therefore, what are the aspects of their technical advantages? Below my graphite board manufacturer in Shanxi Province will introduce the old iron in detail:The antioxidant solution has good performance. Generally speaking, in the whole process of the construction of graphite board projects, the provisions of anti -oxidation levels are getting higher and higher, especially as a wall insulation layer.
