Aluminum nitride nanopowder has ultra-high thermal conductivity

1, thermal silica gel and thermal epoxy resin
Ultra-high thermal conductivity nano AlN composite silica gel has good thermal conductivity, good electrical insulation, wide electrical insulation temperature (operating temperature -60 ° C - 200 ° C), low consistency and good construction performance. The products have reached or exceeded the imported products, because they can replace the similar imported products and are widely used in the heat transfer medium of electronic devices to improve work efficiency. Such as CPU and heat sink caulking, high-power triode, thyristor components, diodes, heat transfer medium at the slits in contact with the substrate. The nano-thermal paste is used to fill the gap between the IC or the triode and the heat sink, increasing the contact area between them to achieve better heat dissipation.
2, the application of thermal plastics
nano aluminum nitride powder can greatly improve the thermal conductivity of plastics. By adding the experimental product to the plastic in a ratio of 5-10%, the thermal conductivity of the plastic can be increased from 0.3 to 5. The thermal conductivity has increased by more than 16 times. Compared with the current thermal conductive fillers on the market (alumina or magnesium oxide, etc.), the addition amount is low, the mechanical properties of the product are improved, and the heat conduction effect is more obvious. At present, relevant application manufacturers have purchased nanometer aluminum nitride powder on a large scale, and new nano-thermal conductive plastics will be put on the market.
3, the application of high thermal conductivity silicone rubber
The procurement and silicon matching performance is good, easy to disperse in the rubber, without affecting the mechanical properties of the rubber (experimental proof of the mechanical properties of the rubber has improved) can greatly enhance silicon The thermal conductivity of rubber does not increase the viscosity very quickly in the process of addition, such as oxides, and the addition amount is small (the thermal conductivity is generally increased by 50%-70% according to the heat conduction requirement), and is widely used in Military, aviation and information engineering.
4, other application areas
Nano aluminum nitride used in the melting of non-ferrous metals and semiconductor materials gallium arsenide, evaporation boat, thermocouple protection tube, high temperature insulation, microwave dielectric materials, high temperature and corrosion resistant structural ceramics and Transparent aluminum nitride microwave ceramic products, as well as current applications and PI resin, thermal insulation mica tape, thermal grease, insulating paint and heat transfer oil.

What is silicon carbide whiskers and its application

Silicon carbide whiskers are a kind of single-crystal fiber with a certain length-to-diameter ratio, which has very good high temperature resistance and high strength. It is mainly used in toughening applications where high temperature and high strength applications are required. Such as: aerospace materials, high-speed cutting tools. At present, it has a very high performance-price ratio. Silicon carbide whiskers are cubic whiskers, and diamonds belong to a crystal form. They are the whiskers with the highest hardness, the largest modulus, the highest tensile strength and the highest heat resistance temperature. It is both α-type and β-type, in which β-type performance is better than α-type and has higher hardness (Mohs hardness of 9.5 or more), better toughness and electrical conductivity, anti-wear, high temperature resistance, especially earthquake resistance Corrosion-resistant, radiation-resistant, has been applied to aircraft, missile casings and engines, high-temperature turbi...

What is boron nitride coating and how to use it?

Product Characteristics Environment Friendly: Boron nitride is environmentally friendly, non-toxic, non-polluting Chemical Properties:  Strong non-stick properties in high temperature environment, stability in high temperature Physical Properties: Electrical insulator, low dielectric constant, good thermal conductivity and high lubricity Product Features: Special formula, water-based, easy to use, long-acting formula This type of coating is suitable for all kinds of release agents which need to be operated at high temperature (the product can withstand high temperature of 2800 C). For example, glass industry, metal welding industry, etc., can effectively lubricate and isolate the interface, which can make the processing more smoothly. Sintering of metal and ceramic powders is usually carried out on graphite plate. After coated with boron nitride coating on graphite, the pollution, reaction and bonding phenomena of carbon on sintered parts which may ...

We have already used titanium dioxide powder in our lives.

Titanium is a chemical element, chemical symbol Ti, atomic number 22, located in the fourth cycle of the chemical periodic table, group IVB. It is a silver-white transition metal characterized by light weight, high strength, metallic luster and resistance to wet chlorine gas. The most common compound of titanium is titanium dioxide, which can be used to make white pigments. In the past, people used to mine titanium ore, the main purpose is to obtain titanium dioxide. 1.The nature of titanium dioxide Titanium dioxide (chemical formula: TiO2) is a white or bulk amphoteric oxide with a molecular weight of 79.83. Titanium dioxide is a compound of titanium, a pure substance composed of two or more elements (different from elemental matter). A compound has certain properties, different from the elements or ions it contains, and other compounds. Properties of crystal form: TiO2 has three main crystal forms such as rutile type, anatase type and plate titanium type. Optical properties: Since T...
