The first reason is to change the inorganic filler from a general incremental filler to a functional filler. Inorganic fillers play an important role in the polymer materials industry and polymer matrix composites such as plastics, rubber and adhesives. Application and function of partially modified inorganic filler Inorganic filler Application Function Calcium carbonate PVC,PE, PP, Unsa...

As the anode material of lithium ion battery, silicon nanopowder has the highest theoretical specific capacity (up to 4200 mAh/g), which is much higher than the carbon powder widely used at present, but the biggest disadvantage of silicon powder as the negative electrode of lithium ion battery is the process of alloying with lithium. In the case of a large volume change, the active material is det...

Transparent conductive films are an important part of many optoelectronic devices, such as flat panel displays, organic solar cells, organic light emitting diodes (OLEDs), smart windows, and the like. Indium tin oxide (ITO) has become the main material of transparent conductive films due to its high electrical conductivity and light transmittance. However, ITO also has some disadvantages, such as ...

1)Silicon carbide whiskers should be pre-dispersed as much as possible before use. They should be mechanically and ultrasonically dispersed with water, ethanol, etc., and then mixed with the matrix material. 2) The amount of silicon carbide whiskers added to the material is not as high as possible, and there is usually an optimum value. Ordinary ceramics are generally added in an amount of 1-10%. ...

Nano silica powder is a filler for reinforcing high-temperature vulcanized silicone rubber. The silica nanopowder aggregates have a good reinforcing effect on the silicone rubber. After adding SAT NANO nano silica powder to the rubber, a microcrystalline region with silica as a nucleus is formed, which increases the physical cross-linking point. Crystallization is more likely to occur and the stre...

1. What is tungsten disulfide powder? Ultrafine WS2 powder is a new type of lubricating and anti-wear material with excellent lubricating properties and its dry friction factor is only 0.03. Tungsten disulfide is one of the best raw materials for friction lubrication in the scientific community. Under static conditions, its dry friction factor is 0.07. Under dynamic conditions, the dry friction fa...

First, powder materials are the key to 3D printing ceramic technology Additive manufacturing (3D printing) is known as the third industrial revolution. For ceramic materials, the properties of raw material powders (such as purity, particle size and distribution, particle morphology, etc.) have a direct impact on the performance of ceramics. . Ideally, the components are characterized by fine contr...

The organic/inorganic nanocomposite formed by dispersing the inorganic filler in a nanometer size in a general plastic matrix is called nanoplastic. In nanocomposites, nano-plastics have excellent properties such as high strength, heat resistance, high barrier properties, flame retardancy and excellent processability due to the nano-size effect of the dispersed phase, large specific surface area a...

The addition of nano SiO2 powder as an admixture to cement-based materials can improve many of the properties of cement-based materials. A large number of research results show that adding appropriate amount of SiO2 nanopowder to cement-based materials, due to the volcanic ash effect of nano SiO2 particle, nucleation effect and micro-filling effect, can significantly improve the early strength of ...

Cubic silicon carbide, Beta SiC, is a synthetic high-performance material (only a small amount of high-purity cubic silicon carbide exists in nature). It is called "cube" because its structure belongs to the cubic system (diamond crystal). This structure also determines its own superior physical and chemical properties. B-SiC has a Mohs hardness range of 9.5 to 9.75, which is close to the most Moh...
