2024-03-12Graphite, this seemingly ordinary black mineral, actually contains endless mystery and value. As the "black gold" in natural minerals, graphite plays an irreplaceable role in many fields with its unique physical and chemical properties.Graphite has excellent electrical conductivity, thermal conductivity and chemical stability, which makes it widely used in electronics, metallurgy, chemical industry and other industries. At the same time, graphite is also an important raw material for the manufacture of pencil leads, lubricants and refractories. Its unique layered structure makes graphite also have broad application prospects in the field of energy storage.However, the mining and processing of graphite is not easy. Because of its low hardness, fragile and dust is easy to fly, it puts forward high requirements for mining technology and environmental protection. At the same time, with the continuous progress of science and technology, people's performance requirements for graphite are be

It is not only an ancient material for writing and painting, but also a key element of modern industry and technology.The unique properties of graphite stem from its layered structure. Each layer of graphite is tightly bound by carbon atoms through covalent bonds, while the layers interact with each other th
2024-03-05Graphite, a seemingly ordinary mineral, has played an important role in human history. From ancient writing materials to modern electrodes, lubricants and new energy materials, the diversity and unique properties of graphite make it constantly adapt to the pace of scientific and technological development.With the progress of science and technology, the application field of graphite is also expanding. In the
2023-12-26Graphite is a transitional crystal between atomic crystals, metal crystals, and molecular crystals. In the crystal, covalent bonds are formed by sp2 hybridization between carbon atoms on the same layer. Each carbon atom is connected to three other carbon atoms, and six carbon atoms form a regular hexagonal ring on the same plane, extending to form a layered structure. Carbon atoms in the same plane each have one p orbital left, which overlaps with each other to form delocalized π - bonds. Electrons can freely move in the lattice and be excited, so graphite has a metallic luster and can conduct electricity and heat transfer. Due to the large distance between layers and the low bonding force (van der Waals force), each layer can slide, resulting in a lower density of graphite compared to diamond, a softer texture, and a smoother texture. [1]The distance between each layer of graphite is 3.40 Å, which is combined by van der Waals forces. The layers belong to molecular crystals, and the d
