High Purity Spherical Aluminum Nitride AlN Granule CAS 24304-00-5, 99.5% | TRUNNANO

About the Spherical AlN Granule



Aluminium nitride spherical

This product is made by the laser flamejet fusion method. The obtained product exhibits high purity, uniform particle sizes distribution, high surface sphericity and no residual impurities. Easy dispersion and high compatibility with other organisms.

Aluminum Nitride Powder

It is then subjected to second laser melting, spherical alloying.


Aluminium nitride sphere

A type of inorganic dust of high temperature conductivity materials. Because of their high thermal conductivity.

Electronic devices of all types are becoming more connected and powerful with the 5G age. To improve heat dissipation properties of many packaging resins in electronics manufacturing, it is possible to incorporate inorganic insulation fillers with high thermal conductivity in to the materials. Aluminum nitride is one such option. The powder must be compacted and spherical with a range of particle sizes from tens to hundreds. This is to improve filling quantity and ensure good fluidity.

How Spherical AlN Granule Is it Produced?

The invention is a process for producing highly pure, quasi-spherical particles of aluminum nitride. This involves the following steps.

(1) To obtain tiny spherical particles, wet Al2O3 powder and water-soluble organ salt according to mass.

(2) Micron-sized spherical sphere particles are placed into a nitrogen atmosphere to microwave synthesis. The synthesis process can be divided into two parts: First, using 0.15% heating from room temperature up to 800 1200 for heat preservation. Second, 120 /min heating to 1200 1800 for heat preservation.

(3) Nano-sized aluminum oxide particles that contained trace carbon were removed in an atmosphere of CO2 and decarbonized to produce high-purity, spherelike particles.

1. Manufacturing high-performance ceramic products: electronic devices and optic devices manufacturing, integrated electric subgrade boards, thermal devices, radiators and the high-temperaturecrucible

2. Excellent applications are possible in preparation of metal matrix composite materials and high temperature sealing adhesives.

3.Nano organic ceramic ceramic automotive oil lubricants and antiwear agent. The nanometer ceramic aluminium nitride clay nanoparticles act as lubricating oils in the engine’s metal surface. Under extreme temperature and pressure, the nano-ceramic coating is formed. This film isolates the friction and reduces the friction between the moving parts. While nano aluminum nitride is costly, there is only two parts per ten million of it in the lubricating fluid. This makes the performance very good.

4. It is used for the manufacture of heat-conducting silica and epoxy resin. Nano-aluminum silica nitride-composite silica gel with high thermal conductivity has excellent thermal conductivity, electrical insulation and wide working temperature. This material is used extensively in the space between CPU/radiator, high-power triodes (SCR components), diodes and heat transfer medium at the thin joints with substrate.

5. High thermal conductivity silicone rubber is made from aluminum nitride.

6. Another area of application is the use of nano aluminum nutride in smelting ferrous metal and semiconductor galium arsenide.

Storage condition of Spherical AlN Granule:

Weak reunions can adversely affect spherical nitride’s dispersion performance. Avoid stress and avoid using spherical nitride.
