2023-12-11Raw material quality: The main raw material for graphite crucibles is natural graphite, and its quality is closely related to the service life of graphite crucibles. High quality natural graphite has the characteristics of high density, high purity, and high strength, which can extend the service life of graphite crucibles.
The main difference between graphite and graphene lies in their structure. Graphite is a two-dimensional material with a hexagonal lattice formed by carbon atoms, and is an allotrope of carbon. And graphene is a type of material composed of carbon atoms in the form of sp ² A two-dimensional carbon nanomaterial with a hexagonal honeycomb lattice composed of hybrid orbitals is a single-layer structure of graphite. Therefore, graphite can be seen as a stacked form of graphene.Graphene has some unique physical and chemical properties, such as excellent conductivity and thermal conductivity, high strength, high toughness, etc., making it have broad application prospects in energy, materials, electronics and other fields. Due to its structure, graphite mainly has excellent lubrication and wear resistance, and is commonly used in the manufacturing of lubricants and wear-resistant materials.Although there are significant differences in structure and properties between graphite and graphene, t2023-12-07The difference and connection between graphite and graphene
2023-12-07Isostatic pressing graphite is a new product developed internationally in the past 50 years, closely linked to today's high-tech industry. It is an irreplaceable material for manufacturing single crystal furnaces, metal continuous casting graphite crystallizers, graphite electrodes for electrical discharge machining, and is also an excellent material for manufacturing rocket nozzles, graphite reactors, deceleration materials, and reflection materials. Its structure is fine and dense, the roasting process requires a particularly slow speed, and the temperature inside the furnace needs to be very uniform. This process takes about 1-2 months. The preparation process of isostatic pressing graphite includes filling the raw material powder into the mold, compacting the powder through high-frequency electromagnetic vibration, sealing and vacuuming, discharging the air between the powder particles, placing it in a high-pressure container containing liquid medium for pressure pressing, and fin
2023-12-06There are differences between graphite and coal in the following four aspects:Composition and structure: Graphite is composed of carbon elements, and its structure is composed of face centered cubic crystal structures. Carbon atoms are connected by strong covalent bonds. Coal, on the other hand, is mainly composed of alkyl groups and aromatic rings, with alkyl groups containing more hydrogen elements.Physical properties: Graphite has excellent conductivity, which is comparable to metals such as copper and silver. Coal, on the other hand, is a type of sedimentary rock containing carbon, which has the characteristics of providing thermal and chemical energy.Usage: Graphite is widely used in the manufacturing of pencil leads, electrodes, refrigerants, ships, anti-corrosion coatings, and lithium batteries due to its conductivity and other excellent properties. Coal, on the other hand, is mostly used as a biofuel and is widely used in fields such as power generation, barbecue, and water he
2023-12-06Graphite is an allotrope of carbon with various excellent properties, and is therefore widely used in many fields. The following are the main functions and uses of graphite:
2023-12-05Natural flake graphite is a non-metallic mineral with unique physical and chemical properties such as high temperature resistance, oxidation resistance, corrosion resistance, thermal shock resistance, high strength, good toughness, high self-lubricating strength, strong thermal conductivity and conductivity.
