Compared with other fillers, although the thermal conductivity of alumina is not the best, it can meet the basic thermal conductivity requirements. And the alumina price is lower, the source is wider, is economical suitable filler of the high thermal conductivity insulation polymer.Hwnanomaterial can batch produce white alumina powder with narrow particle size distribution, stable process and high thermal conductivity coefficient. particle size in 1um, 500nm, 300nm, 200nm, etc. According to the customer’s feedback, the thermal conductivity can reach 3-10w/(m*K) according to different filling quantity.

Heat-conducting alumina can be widely used in different materials such as silica gel, sealing adhesive, epoxy resin, plastic, heat-conducting rubber, heat-conducting plastic, silicone grease, heat-conducting ceramic and so on. In practical application, Al2O3 powder filler can be used alone or mixed with other fillers such as AIN and BN. In order to provide dispersibility of alumina powder, the surface of alumina can be modified by silane coupling agent or hexadecyl trimethoxy silane.Hwnanomaterial can batch produce white alumina powder with narrow particle size distribution, stable process and high thermal conductivity coefficient. particle size in 1um, 500nm, 300nm, 200nm, etc. According to the customer’s feedback, the thermal conductivity can reach 3-10w/(m*K) according to different filling quantity.

Gamma Al2O3 nanopowder has a large SSA, high porosity, strong heat resistance and surface acidity, good formability and certain surface alkalinity. It is widely used as a new green chemical material such as catalyst and catalyst carrier. The actived nano alumina powder exhibits a white fluffy powder state, and the crystal form is gamma. The particle size is 20-30 nm. The specific surface area is >130 m 2 /g. Narrow particle size distribution, high purity up to 4N, easy dispersion, high specific surface area, high temperature inertness and activity, also called actived alumina.

Application of Gamma Al2O3 nanoparticles:

gama Al2O3 nanoparticles has a large specific surface, high porosity, strong heat resistance, good formability, strong surface acidity and certain surface alkalinity, and is widely used as a catalyst and a catalyst carrier. When the alumina powder particle size extends down to the nanometer level, while maintaining the excellent characteristics of the ordinary alumina powder, it exhibits optical, electrical, magnetic, thermal and mechanical properties not possessed by conventional materials, and nano-alumina. As a new functional material, it is widely used in many fields such as optics, chemical industry and special ceramics.

1. dehydration air, natural gas, petroleum cracking gas

2. fluoride in drinking water

3. special catalyst anthraquinone production of hydrogen peroxide

4. sticky resin dechlorination

5. the catalyst carrier

6. air separation and oxygen industry-specific

7.Alumina is one of the most widely used oxide ceramic material. It is interesting to underline that γ-Al2O3 has significant applications as catalyst support.For all of these applications, the challenge remains a controlled synthesis of the alumina nanoparticles as in most of the research works in Nanoscience and Nanotechnology.

8.The importance of nano alumina nanoparticles is due to the high pressure solidity, high strength, high resistance to erosion, high heat conduction, and high electrical resistance, transparency in front of frequencies or microwave blaze.

9.Alumina nanoparticles has many applications in which its properties of extraordinary hardness and thermal stability are exploited. Examples of products incorporating aluminium oxide include abrasive materials, bone substitutes, melting pots and watch glasses. Aluminium oxide is a classic antacid remedy for heartburn.

10. Gama al2o3 has a strong adsorption capacity and catalytic activity, it is also known as activated alumina which typically it belongs centered cubic close-packed configuration, square crystal, spinel structure is very similar to that in many chemical reactions was used as adsorbents, catalysts and catalyst carriers, such as petroleum hydrocracking, hydrodesulfurization, and the dehydrogenation catalyst carrier or the like, and therefore is an excellent gama-alumina catalyst.

11. For forging furnace, soaking furnace and other industrial high temperature furnace.

12. Can be used for the sealing material and the filler material can also be reinforced with reinforcing fibers calciner, electronic components.

13. Is mainly used as chemical fiber filler, but also for cosmetic face cream mill grinding surface agents, toothpaste friction agents metallurgy and chemicals.

14. Analysis of the preparation of reagents, adsorbents dehydrated organic solvent, an abrasive, low melting point lead glass

  • Gama aluminum oxide, activated alumina, Gama al2o3 used for adsorbent:

Activated alumina having a plurality of capillary channels, large surface area, can be used as an adsorbent, desiccant and catalyst. Also according to the polarity of the adsorbed species to determine the strength of the water, oxides, acetic acid, alkali and other strong affinity, is a micro water depth of desiccant, adsorbent is adsorbed polar molecules. Activated alumina fluoride removal similar to the anion exchange resin, but the fluoride ion selective anion resin large.

Activated alumina adsorption defluorination effect, stable capacity per cubic meter of active alumina suction fluorine 6400 g. This product has high strength, low wear, flooding the same soft, not inflated, not powder, not rupture.

Activated alumina can be widely used in petroleum cracking gas, depth ethylene propylene gas drying and hydrogen, dry air separation plant, instrument air-dry machines, hydrogen peroxide, fluoride treatment can also remove the sulfur in the exhaust gas of hydrogen, sulfur dioxide, hydrogen fluoride, hydrocarbons and other pollutants, particularly adapted to fluoridated water the fluoride treatment.
