  • Alumina - an overview | ScienceDirect Topics
    Alumina is a valuable raw material used in the production of various products such as adsorbents, abrasives, polishing agents, refractory materials, and aluminum It is obtained from bauxites through the Bayer process and requires the removal of certain organic compounds to enhance its production From: Journal of Hazardous Materials, 2020
  • Recent processes for the production of alumina nano-particles
    Alumina nano-particles have wide usage in the adsorption and catalysis fields, because of its acid-base properties, high specific area, mechanical and thermal stability The first part of the review interested on the various processes for the production of nano-particles alumina
  • Chemistry of alumina, reactions in aqueous solution and its application . . .
    Most solid phases in natural water contain aluminium oxides Alumina plays an important role in regulating the composition of soil–water, sediment–water, and other natural water systems [11] Active alumina, due to its high surface area, mechanical strength and thermal stability has found several applications as an adsorbent and catalyst
  • High-temperature mechanical properties and thermal . . . - ScienceDirect
    An alumina-fiber-reinforced alumina ceramic matrix (Al 2 O 3 Al 2 O 3) composite is fabricated by a slurry infiltration process in this study The slurry contains Al 2 O 3 powders with broad particle size distribution (d 10 = 0 35 μm, d 50 = 0 57 μm, d 90 = 1 90 μm)
  • Structural, Surface, and Catalytic Properties of Aluminas
    The published data concerning the structural, surface, and catalytic properties of aluminas are reviewed, and these properties are related to the prep…
  • Organized mesoporous alumina: synthesis, structure and potential in . . .
    Alumina is a very interesting material with broad applicability as a support for various catalytically active phases, which are employed in industry in a high number of large-scale technological processes [10], [11] Usually, conventional aluminas with surface areas of 50–300 m 2 g are manufactured by precipitation [12]
  • Alumina Production - an overview | ScienceDirect Topics
    Alumina is the most widely used of the twenty or so oxide ceramics and is often regarded as the historic forerunner of modern engineering ceramics The actual content of alumina, reported as Al 2 O 3, ranges from 85% to 99 9%, depending upon the demands of the application
  • Kinetics and properties of porous alumina with a dense surface layer . . .
    Porous alumina with a dense surface layer was prepared via pressureless sintering of bimodal powders followed by vacuum impregnation using a nano-alumina sol Optimal properties (>25 % porosity, >500 MPa compressive strength) were achieved at 1200 °C using 6 wt% 600 nm alumina mixed with 200 nm powder
  • Alumina fibers: composites and applications - ScienceDirect
    Alumina, also known as aluminum oxide, is a white powder that is highly resistant to chemical corrosion This refractory oxide has a melting point of 2024°C, making it a popular choice for high-temperature applications Alumina fiber is created by spinning a solution that contains an aluminum compound and an organic polymer
  • Alumina ceramics - ScienceDirect
    Alumina is the most widely produced oxide ceramic material with widespread use in various applications from engineering through biomedical [13] However, further studies are still needed to be conducted, especially evaluating the role of alumina nanoparticle in the alteration of drilling mud properties
