Catalyst Carrier Used Near Spherical Gama Aluminum Oxide Nanoparticles

Spec: 20-30nm, 99.99%, near spherical, gama

Application for aluminum oxide nanoparticles:

1. The sintered ceramic additives: aluminum oxide nanoparticles, large surface area, and have a higher rate of diffusion, thus using nano-powder sintering, densification fast, can also reduce the sintering temperature. Nano-alumina powder added to the conventional 85 porcelain, 95 porcelain observed uniform organizational strength and toughness. Nano-alumina ceramic sintering temperature 400 degrees Celsius lower than conventional micron-sized zirconia ceramic temperature.

2. Composite Additives: As dispersion strengthening and use of additives, such as cast iron lap, when casting with nano-alumina powder as nucleation deterioration, wear grams increased several times over. Nano-alumina as a composite material can also be used to make artificial teeth and bones.

3. The surface protection layer material: the use of the method in surface spray metal, ceramic, plastic and carbide aluminum oxide nanoparticles after spray can improve the surface hardness, corrosion resistance and wear resistance. It can be used for surface protection machinery, tools, pipes and other chemicals.

4. Optical Materials: aluminum oxide sintered into another on the body can be as high pressure sodium lamp tube transparent ceramic materials and rare earth fluorescent compound can also be used as a light-emitting material fluorescent tubes.

5. catalyst and carrier

6. The semiconductor material: nano-alumina is the sensitive nature of the humidity, the temperature sensor has a very high value. It can also be used for large scale integrated circuit substrate material.
