�-Al2O3 synthesis from m-Al2O3

Journal of Applied Electrochemistry, 1980
β-Al2O3 formation fromm-Al2O3 was found by a new convenient technique. By thermal decomposition of a complex compound, trioxalatoaluminate Na x (NH4)3−x [Al(C2O4)3]yH2O(0.091 ⩽x ⩽ 0.333;y= 3), a very fine powder ofm-Al2O3 was formed.

Interfacial reactions in Al2O3/Ti, Al2O3/Ti3Al and Al2O3/TiAl bilayers

Thin Solid Films, 1999
Abstract Interfacial reactions were studied at three different heat-treated oxide/metal bilayers (oxide: amorphous a-Al 2 O 3 and metal: crystalline c-Ti, Ti 3 Al or TiAl) by means of AES depth profiling. The different oxide/metal bilayers were sputter deposited on smooth silicon substrates, covered with a TiN thin-film diffusion barrier.

Radial profiles in Pt/Al2O3, Re/Al2O3 , and Pt-Re/Al2O3

Applied Catalysis, 1984
Abstract The competitive effect of HCl on H2PtCl6 and/or HReO4 deposition on γ-Al2O3 was studied. For this purpose HCl, H2PtCl6, and HReO4 adsorption isotherms were determined, and the radial distribution profiles of the three components were obtained by impregnating cylindrical tablets.

Slip casting of Al2O3 and Al2O3/ZrO2 composites

Journal of Materials Science, 1990
Al2O3 and Al2O3/ZrO2 composites have been fabricated by slip casting from aqueous suspensions. The physical and structural characteristics of the starting powders, composition of the suspensions, casting behaviour, microstructure of the green and fired bodies and the mechanical properties of the products were investigated. The addition of ZrO2 to Al2O3

Effective fracture toughness in Al2O3–Al2O3/ZrO2 laminates

Journal of the European Ceramic Society, 2007
During the processing of laminar ceramics, biaxial residual stresses can arise due to the thermal mismatch between different layers. For ceramic multilayers, the beneficial consequences of compressive stresses at the surface are well known: increase in strength, apparent toughness and reliability. Nevertheless, the resulting tensile stresses may induce
