- Alumina - an overview | ScienceDirect Topics
Alumina is defined as a chemical compound derived from aluminum ore bauxite, serving as a key raw material for the aluminum industry It is characterized by its abundance and ease of processing compared to other sources like corundum
- Alumina Production - an overview | ScienceDirect Topics
Alumina production refers to the process of extracting alumina (aluminum oxide) from bauxite ore, primarily through the Bayer process, which involves digestion of bauxite in caustic soda, followed by precipitation and calcination to produce a white powder
- 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…
- Recent processes for the production of alumina nano-particles
Abstract 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
- Soft alumina-based thermal interface materials with enhanced thermal . . .
Soft alumina-based thermal interface materials with enhanced thermal properties enabled by the synergistic effect with hexagonal boron nitride and liquid metal
- Chemistry of alumina, reactions in aqueous solution and its application . . .
Due to the common presence of alumina in the natural aquatic environment, several applications in water treatment technology and also its wide industrial application, the understanding of the chemistry of alumina in water is necessary in order to fully comprehend the mechanisms governing the reactions at solid–liquid interface
- The surface of transitional aluminas: A critical review
The actual existence of several polymorphs of alumina, necessarily having slightly different stability, and their possible use in catalysis in the same conditions, with slightly different behaviors, is a proof of the weakness of the argument of lower higher thermodynamic stability to exclude confirm an hypothetical structure
- Joining alumina to metals: Technologies, challenges, and future . . .
Joining alumina to metal presents several challenges due to differences in material properties, especially since alumina has a lower coefficient of thermal expansion (CTE) compared to most metals, creating a thermal expansion mismatch during heating and cooling cycles, which can lead to residual stresses at the interface
