  2. Aluminium oxide nanoparticle - Wikipedia

    en.wikipedia.org/wiki/Aluminium_oxide_nanoparticle

    2. The decomposition of fresh chemically-synthesized AlOOH or Al(OH) 3 to aluminium oxide in the rapid achievement of the temperature of decomposition 175 °C and use for it the pressure of 5 bars within thirty minutes. The sooner of the temperature of decomposition of the hydroxo-compounds of aluminium is achieved, the smaller the resulting ...

  3. Anodic aluminium oxide - Wikipedia

    en.wikipedia.org/wiki/Anodic_aluminium_oxide

    Anodic aluminum oxide, anodic aluminum oxide (AAO), or anodic alumina is a self-organized form of aluminum oxide that has a honeycomb-like structure formed by high density arrays of uniform and parallel pores. The diameter of the pores can be as low as 5 nanometers and as high as several hundred nanometers, and length can be controlled from few ...

  4. Aluminium oxide - Wikipedia

    en.wikipedia.org/wiki/Aluminium_oxide

    Aluminium oxide is used for its hardness and strength. Its naturally occurring form, corundum, is a 9 on the Mohs scale of mineral hardness (just below diamond). It is widely used as an abrasive, including as a much less expensive substitute for industrial diamond. Many types of sandpaper use aluminium oxide crystals.

  5. Halloysite - Wikipedia

    en.wikipedia.org/wiki/Halloysite

    Halloysite can also be used to produce porous silicon nanotubes as anode materials for Li-ion batteries through the selective etching of aluminium oxide and thermal reduction. [30] As a nanofiller in nanocomposite e.g. thermoplastic polyurethane acting on the mechanical, physicochemical and biological properties. [31]

  6. Ceramic nanoparticle - Wikipedia

    en.wikipedia.org/wiki/Ceramic_nanoparticle

    Ceramic nanoparticle is more than 85% air and is very light, strong, flexible and durable. The fractal nanotruss is a nanostructure architecture [3] made of alumina, or aluminum oxide. Its maximum compression is about 1 micron from a thickness of 50 nanometers. After its compression, it can revert to its original shape without any structural ...

  7. Nanofoam - Wikipedia

    en.wikipedia.org/wiki/Nanofoam

    Also, metal nanofoams can be made by electrodeposition of metals inside templates with interconnected pores, such as 3D-porous anodic aluminum oxide (AAO). [5] [6] [7] Such method gives nanofoams with an organized structure and allows to control the surface area and porosity of the fabricated material. [8] [9] [10]

  8. Aluminium oxides - Wikipedia

    en.wikipedia.org/wiki/Aluminium_oxides

    Aluminium(I) oxide (Al 2 O) Aluminium(II) oxide ( AlO ) (aluminium monoxide) Aluminium(III) oxide (aluminium oxide), ( Al 2 O 3 ), the most common form of aluminium oxide, occurring on the surface of aluminium and also in crystalline form as corundum , sapphire , and ruby .

  9. Activated alumina - Wikipedia

    en.wikipedia.org/wiki/Activated_alumina

    The compound is used as a desiccant (to keep things dry by adsorbing water from the air) and as a filter of fluoride, arsenic and selenium in drinking water. It is made of aluminium oxide (alumina; Al 2 O 3). It has a very high surface-area-to-weight ratio, due to the many "tunnel like" pores that it has.
