Preparation and Characterization of FeCo-Al2O3 and Al2O3 Aerogels

Journal of Sol-Gel Science and Technology, 2004
Nanocrystalline γ-Al2O3 and FeCo-Al2O3 nanocomposites containing FeCo alloy nanoparticles well dispersed in the nanocrystalline γ-Al2O3 matrix were successfully obtained by the sol-gel method using aluminum tri-sec-butoxide and iron and cobalt nitrates as precursors.

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

�-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.

Role of Al2O3 in Al2O3–Bi2O3–P2O5 glasses

Applied Physics A, 2021
Research on ternary Al2O3–P2O5–Bi2O3 glasses had been achieved. The changes in density and ultrasonic velocities were used to determine the elastic moduli and Debye temperature of the glasses. The investigated ultrasonic parameters were correlated with the structural variations represented by the FTIR spectra to examine the function of Al2O3 in the ...
