Graphite is an allotrope of carbon. It is a gray-black, opaque solid with stable chemical properties, corrosion resistance, and is not easy to react with chemicals such as acids and alkalis. Natural graphite comes from graphite deposits, and can also be made of artificial graphite using petroleum coke, pitch coke, etc. as raw materials after a series of processes. Graphite burns in oxygen to generate carbon dioxide, which can be oxidized by strong oxidants such as concentrated nitric acid and potassium permanganate.
Graphite products have good adsorption properties. The carbon pore structure makes carbon have good adsorption, so carbon is often used as an adsorption material for adsorbing water, odors, toxic substances, etc. We have done experiments. The graphite of the barbecue plate used a few days ago looks very clean, but when the induction cooker is heated, we will see that the last barbecue oil and the adsorption of harmful substances will slowly seep out, but don't worry, use a piece of clean kitchen paper is ready to use.
Graphite products, such as graphite carbon block, have good thermal conductivity, fast heat transfer, uniform heating and fuel saving. Baking pans made of graphite, such as frying pans, heat quickly, burnt food is heated evenly, cooked from the inside out, and the heating time is short, not only the taste is pure, but also the original nutrition is preserved. Food can be locked. One of the main uses of graphite is in the production of refractory materials, including refractory bricks, crucibles, continuous casting powder, cores, molds, cleaners and high temperature resistant materials. In recent years, two important changes in the refractory industry are the widespread application of magnesia-carbon bricks in steelmaking furnace linings, and the application of aluminum-carbon bricks in continuous casting processes. Graphite refractories are closely related to steelmaking refractories, and the world's steel industry is about consumption. When baking with a graphite baking pan, turn on the induction cooker and preheat for 20 to 30 seconds. When starting food, only a small fire can be used, which has the advantage of energy saving.
Graphite products, like graphite blocks for machining, have chemical stability and corrosion resistance. Graphite has good chemical stability at room temperature and does not contain any strong acid, strong alkali and organic solvent. Therefore, even if the graphite products are used for a long time, the loss is very small, as long as they are cleaned and replaced.
Graphite products have strong oxidation resistance and reducibility. The product, especially the graphite mattress, can generate negative oxygen ions after heating, which can activate the surrounding items, maintain human health, effectively prevent aging, and make the skin full of luster and elasticity.
Graphite products are environmentally friendly, healthy, free of radioactive pollution and high temperature resistance. Carbon becomes graphite after at least ten days of graphitization in a high temperature environment of 2000~3300 °C. Therefore, the toxic and harmful substances in graphite have been released and exhausted, and it is stable at least within 2000 °C.
