  Overview of graphite Graphite  is an important non-metallic mineral resource and an allotrope of carbon. The different crystal forms of graphite determine that it contains various industrial values and uses. In industry, graphite ore is divided into crystalline (flaky) graphite ore and cryptocrystalline (earth-like) graphite ore according to the different forms of graphite crystals. From a mineralogical point of view, generally speaking, graphite is crystalline graphite, and cryptocrystalline graphite also belongs to crystalline graphite. Cryptocrystalline graphite is crystalline graphite that can only be seen under an electron microscope. Therefore, different classification methods have different classification results. This article mainly adopts the industrial classification method, which is closer to the application and classification of graphite in industry. Crystalline graphite ore can be divided into scaly and dense. The scaly graphite ore crystallizes better, the crystal size

  The sustainable development   of energy and the environment are two important development strategies of today's human society. With the development of the global economy, people's demand for energy is increasing, and the development of new energy is imperative. At the same time, nanotechnology as new technology requires a good operating space. The new energy field has large investment, rapid development, low starting point, and low reform cost, which is very suitable for the introduction and development of a variety of nanotechnologies. One of the most promising applications is to improve the performance of solar cells. In the field of wind energy, although most of them are still in the laboratory stage, they still have very broad application prospects. In addition, there are many other new energy nano applications, such as hydrogen storage batteries, which also have great value. Under the dual pressure of energy crisis and environmental problems. Solar, wind, and other inexh

  Overview of Aluminum Nitride Aluminum nitride  (a covalent bond compound) is a diamond-like nitride, hexagonal crystal system, wurtzite crystal structure, non-toxic, white, or off-white atomic crystal. The molecular formula of aluminum nitride is AlN. Aluminum nitride is metal treated and can replace aluminum oxide and tantalum oxide in a large number of electronic instruments. Aluminum nitride can be prepared by reducing aluminum oxide and carbon or by directly nitriding aluminum. Aluminum nitride ceramic properties: Aluminum nitride powder  has high purity, small particle size, and high activity, and is the main raw material for manufacturing high thermal conductivity aluminum nitride ceramic substrates. Aluminum nitride ceramic substrate has high thermal conductivity, low expansion coefficient, high strength, high-temperature resistance, chemical resistance, high resistivity, and low dielectric loss, and is an ideal large-scale integrated circuit heat sink substrate And packaging

  3D printing powder overview 3D printing powder  is metal powder reduced to fine particles.3D printing metal powder is the main basic material for most 3D printing processes used to produce metal parts.3D printing (3DP) is a rapid prototyping technology, also known as additive manufacturing. It is a technology-based on digital model files that uses bondable materials (such as metal powder or plastic) to construct objects by printing layer by layer. The characteristics of the metal powder determine the type of 3D printing process. The performance of the powder depends on its production method, which may result in different particle morphology and purity. Application of 3D printing powder 3D printing  is usually achieved through material printers that use digital technology. It is usually used in mold manufacturing, model making in the field of industrial design, and then gradually used in the direct manufacturing of certain products. There are already parts printed using this technolog

 Lithium battery anode material description The negative electrode of a lithium-ion battery is made by mixing the negative active material carbon material or non-carbon material, binders, and additives to form a paste glue that is evenly smeared on both sides of the copper foil, dried, and rolled. Several layers of graphene (CAS 1034343-98-0) are two-dimensional carbon nanomaterials composed of carbon atoms and sp² mixed orbital hexagonal honeycomb lattice. Few graphene layers are one of the strongest materials known, but they also have good toughness and can be bent. A lithium-ion battery is a kind of secondary battery (rechargeable battery), which mainly relies on the movement of lithium ions between the positive electrode and the negative electrode to work. During charge and discharge, Li+ intercalates and deintercalates back and forth between the two electrodes: during charging, Li+ is deintercalated from the positive electrode and inserted into the negative electrode through the e

  Overview of Spherical quartz powder Spherical quartz powder  is purified and ultra-finely pulverized from natural quartz stone and passed through a certain high-temperature field to make its phase, crystal, and shape change instantaneously, from solid to molten and then to solid, from crystalline to crystalline Amorphous state, a powder obtained from irregular angular particles into regular spherical particles. Its preparation methods currently generally include the high-temperature plasma melting method, high-temperature melting spray method, and gas combustion flame method. Spherical quartz powder has excellent properties such as smooth surface, large specific surface area, high hardness, and stable chemical properties. First of all, the spherical powder has good fluidity and is uniformly mixed with the resin to form a film. The amount of resin added is small, the filling amount of quartz powder is high, and the mass fraction can reach 90.5%. The higher the filling amount of quartz

  Overview of Cuprous oxide  Cu2O  Powder Cuprous oxide,   the chemical formula is Cu2O, is monovalent copper oxide, a bright red powder solid, almost insoluble in water, in acidic solution disproportionation into copper and copper elemental, in the wet air gradually oxidized into black copper oxide. Cuprous oxide is mainly used in the manufacture of ship bottom antifouling paint(used to kill lower Marine animals), insecticides, and various copper salts, analytical reagents, red glass, but also used in the preparation of copper plating and copper plating alloy solution. Copper(I)oxide is also known as an inorganic compound of copper oxide with the chemical formula Cu2O. It's essentially covalent. The copper(I)oxide crystallizes in a cubic structure. When heated, hydrogen tends to reduce the disproportionation it undergoes in acidic solutions that produce copper (II) ions and copper. When the copper oxide is gently heated with metal copper, it is converted to cuprous oxide. It acts
