Effect of alumina occurrence on sintering performance of iron ores and its action mechanism
Journal of Materials Research and Technology, 2021 Iron ores always contain several forms of alumina, which may have different effect on sintering performance. In this paper, sinter pot tests were systematically conducted with various alumina types and contents by means of alumina additives substituting ...

Alumina applied in bone regeneration: Porous α-alumina and transition alumina
Cerâmica, 2022 Abstract Alumina is a polymorphic bioceramic that has been extensively investigated for application in bone regeneration. Dense α-alumina has been considered a suitable biomaterial for dental and orthopedic implants due to its superior mechanical properties. However, its use is limited due to its high inertia in a biological environment.

International Journal of High Technology Ceramics, 1986 Relatively large Al2O3 disc particles (16μm, 41μm) with high aspect ratios (5-20) were incorporated into a fine-grain Al2O3 matrix (-1μm) in order to improve the mechanical properties of sintered Al2O3. The flexural strength depends on the disc size and the microstructure of composites.

An efficient route to aqueous phase synthesis of nanocrystalline γ-Al2O3 with high porosity: From stable boehmite colloids to large pore mesoporous alumina [PDF]
, 2012 In this paper we emphasise the important role of Pluronic F127 on the porosity of mesoporous alumina prepared from boehmite colloids. By focusing on the F127/boehmite interactions we show how the concepts of interface science may help to predict and ...
