According to the application, it can be divided into semiconductor associated ceramic target, display ceramic target, magnetic recording ceramic target, optical recording ceramic target, superconducting ceramic target, giant magnetoresistance ceramic target, etc. Semiconductor association ceramic target material (HfO, the SiO, Si3N4, MoSi, slipped, WSi, TiSi, PLZT, ITO, is mainly used in gate dielectric film.
Nanomaterials refer to ultrafine materials with a grain size of nanometer level (1 m). Their sizes are between molecules, atoms and bulk materials. They generally refer to tiny solid powders in the range of 1 ~ 100nm. Nanomaterial is a kind of third kind of solid material which is different from both crystalline and amorphous state.
Titanium dioxide (TiO2) is a hard and chemically resistant white titanium oxide. Titanium dioxide (TiO2) sputtering target can be used to obtain high quality titanium dioxide thin film, which has been widely used in various applications due to its coating characteristics. Titanium dioxide film provides opacity and durability while helping to ensure paint life and paint surface protection.
Rare earth elements themselves have abundant electronic structures and exhibit many optical, electric and magnetic properties. After nanocrystallization, rare earth exhibits many characteristics, such as small size effect, high specific surface effect, quantum effect, strong optical, electrical and magnetic properties, superconductivity, high chemical activity, etc.
The preparation methods of metal powder can be divided into reduction method, electrolysis method, grinding method, atomization method and so on. At present, argon atomization and plasma rotating electrode are the two most advanced pulverizing processes in China. Argon atomization powder making method is to use the fast flowing argon flow to impact the metal liquid, break it into fine particles, and then condense into solid powder.
LiLithium iron phosphate battery is a lithium ion battery which uses lithium iron phosphate (LiFePO4) as the cathode material and carbon as the cathode material. The rated voltage of single cell is 3.2V and the cut-off voltage of charge is 3.6V~3.65V. There are four main production materials of lithium iron phosphate battery: anode material, anode material, electrolyte and diaphragm.

As a semiconductor material, gallium oxide is easier to achieve high voltage than silicon (Si), gallium carbide, and silicon carbide materials and has stable performance, so it is a good material to save power. As a semiconductor material, gallium oxide is easier to achieve high voltage than silicon (Si), gallium carbide, and silicon carbide materials and has stable performance, so it is a good material to save power.
LMO has no precious metals and its price is relatively low; NCM suffers from high cobalt price and high price (high nickel material can reduce BOM cost, but increase process cost). LMO voltage platform is high, ~3.75~3.8V, NCM voltage platform is low, 3.6-3.7V. LMO spinel structure, safety is relatively better; NCM layered structure, easy to mix lithium nickel, poor safety (the higher Ni%, the worse).
Because the molecular structure characteristics of hexagonal boron nitride, so it has many excellent properties, such as high thermal conductivity, high heat resistance, good lubricity, low friction coefficient, low thermal expansion coefficient, excellent dielectric properties and other physical properties, it also has the strong oxidation resistance, corrosion resistance is strong, stable chemical properties and chemical properties.
Titanium alloy, aluminum alloy, stainless steel, there are a lot of metal powder materials that can be used for 3D printing. There are four kinds of printing consumables widely used in 3D printing: liquid photosensitive resin material, thin material, low melting point silk material and powder material.
Magnetic material and magnetic material are one meaning, but the name is not the same! Rare earth permanent magnet material is a kind of magnetic material made of samarium, neodymium mixed rare earth metal and transition metal (such as cobalt, iron, etc.) alloy by powder metallurgy pressing sintering, magnetized by magnetic field.
In terms of power lithium battery, in terms of passenger cars, foreign countries take modified lithium manganate and ternary lithium battery as the main materials. In China, lithium iron phosphate is mainly used as the main material, but due to the low energy density of lithium iron phosphate, the current trend to ternary lithium battery.
The use temperature of high temperature alloy powder of general quality is mainly in the range of one hundred degrees Celsius to nine hundred degrees Celsius, but because of the different elements in the alloy powder, there is a certain gap in the performance. Elements such as nickel in iron based high temperature alloy powder make it suitable for moderate temperature use.
At present, the target materials are mainly prepared by casting and powder metallurgy. 1. Casting method: the alloy raw material with a certain composition ratio is melted, and then the alloy solution is poured into the mold to form ingot, and finally the target is made by mechanical processing, and the casting method is melted and cast in vacuum.
