Product Properties and Preparation of Aluminum Nitride AlN Powder

Roche and its subsidiary TIB Molbiol have developed a series of tests for the detection of the monkeypox virus, the Switzerland-based pharmaceutical company announced.  

The monkeypox virus is a close relative of the smallpox virus, belonging to orthpoxviridae in the poxviridae family.  

The modular virus detection tool, called LightMix, includes three orthpoxvirus detection kits with different functions, Roche said in a statement. The first kit detects orthpoxvirus; The second kit tests only for monkeypox virus (west and Central African branches); The third kit contains the main functions of the first two kits, showing specific information on the presence of the monkeypox virus (west and Central African branches) as well as the detection of orpoxvirus.

Thomas Schinek, a Roche executive, said the new test could detect monkeypox and help track its spread. Such diagnostic tools are critical for addressing and ultimately managing emerging public health challenges, as they advance responses such as tracking efforts and treatment strategies.  

The monkeypox virus was first identified in 1958 in a group of monkeys used for research when the animals developed a "pox-like" infection, hence the name. Since May, several non-endemic countries have reported human cases of the monkeypox virus, including the United Kingdom, the United States, Portugal, Spain, and Italy.

Overview of spherical aluminum nitride AlN particles

Spherical aluminum nitride is an inorganic powder with high thermal conductivity. Due to its high thermal conductivity, good insulation, low dielectric constant, and the considerable expansion coefficient and excellent comprehensive properties of silicon materials, it is more and more favored by people. Note that it is widely used in large-scale integrated circuits, electronic substrates, high thermal conductivity, thermally conductive inorganic fillers, high-performance structural ceramics and other fields.


With the advent of the 5G era, various electronic devices are becoming more and more integrated and their functions are becoming more and more powerful. In order to improve the heat dissipation performance of various encapsulation resins used in the electronic field, the best way is to add inorganic insulating fillers with high thermal conductivity to the materials. Aluminum nitride is one of the best options. In order to increase the filling amount, the powder is required to be dense and spherical, and the particle size ranges from tens of microns to hundreds of microns, so as to ensure that the particle size and particle size of the composite material can achieve high filling and good fluidity.

Product properties of aluminum nitride AlN powder

The aluminum nitride powder (CAS 24304-00-5) sold by our company has high purity, ultra-fine particle size and high surface activity. The powder is treated with surface cloth, with extremely low oxygen content (<0.1%), thermal insulation and thermal conductivity. The performance effect is obvious.

How is aluminum nitride AlN powder produced?

Thermal Spray Process: Aluminum Nitride powders can be thermally sprayed to form electrically insulating and thermally conductive coatings. Chemical/Physical Vapor Deposition (CVD/PVD): Aluminum nitride coatings are deposited by CVD or PVDto provide an electrically insulating and thermally conductive coating.

Application of spherical aluminum nitride AlN particles

1. Manufacturing of high-performance ceramic devices: manufacturing integrated circuit substrates, electronic devices, optical devices, heat sinks, and high-temperature crucibles

2. Preparation of metal and polymer matrix composite materials: It has good application prospects especially in high temperature sealants and electronic packaging materials.

3. Nano-inorganic ceramic automotive lubricants and anti-wear agents. Nano-ceramic aluminum nitride ceramic nanoparticles are used as lubricants on the metal surface of engine friction pairs. They are activated by high temperature and extreme pressure and are highly permeable. In the depressions and pores of the metal surface, repair the damaged surface and form a nano-ceramic coating. Due to the isolation of this film, the frictional force is greatly reduced and the frictional force between the moving parts is reduced to almost zero. Although nano aluminum nitride powder is expensive, the addition amount in lubricating oil is only two thousandths, and the cost performance is very high.

4. For the manufacture of thermally conductive silica gel and thermally conductive epoxy resin. Ultra-high thermal conductivity nano-aluminum nitride composite silica gel has good thermal conductivity, good electrical insulation, wide electrical insulation temperature, low consistency and good construction performance. Widely used in the gap between CPU and heat sink, high-power transistors, thyristor elements, diodes, and heat transfer media at thin joints in contact with substrates.

5. The application of aluminum nitride powder in high thermal conductivity silicone rubber: the bottom aluminum and silicon nitride have good matching performance and are easy to disperse in the rubber. It can greatly improve the thermal conductivity of silicone rubber without affecting the mechanical properties of the rubber. Like oxides, the viscosity rises rapidly during the addition process, and the addition amount is very small. It is widely used in military, aviation and information engineering.

6. Other application fields: Nano-aluminum nitride is used for smelting non-ferrous metals and semiconductor GaAs crucibles, evaporation boats, thermocouple protection tubes, high-temperature insulating parts, microwave dielectric ceramic materials, high-temperature corrosion-resistant structures, microwave transparent aluminum nitride Ceramic products, currently used in PI resin, thermal insulation mica tape, thermal grease, insulating paint, thermal oil, etc.

Since February, gold has enjoyed a smooth upward run on the back of surging US inflation and the brewing of war. While expectations of rate rises have also risen in tandem over this period, gold had been largely pre-priced and the underlying driver of tightening expectations had come from inflation continuing to rise to record highs. The risk aversion caused by the continued tension in the war also provided an important short-term support for gold. This will have a certain impact on the price of the Spherical Aluminum Nitride, Spherical Aluminum Nitride Overview, Spherical Aluminum Nitride Application, Spherical Aluminum Nitride Supplier, Spherical Aluminum Nitride Price and the market of the Spherical Aluminum Nitride, Spherical Aluminum Nitride Overview, Spherical Aluminum Nitride Application, Spherical Aluminum Nitride Supplier, Spherical Aluminum Nitride Price.
