Co-precipitated ZnAl2O4 spinel precursor as potential sintering aid for pure alumina system

Composition-structure-function correlation of Ca/Zn/AlOx catalysts for the ketonization of acetic acid

“…The ZnAl2O4 particles, formed by ZnO and alumina at high temperature (e.g. 800 o C) [38], are agglomerated inside the crosslinked structure of alumina [52] and hardly to be identified on surface. In Fig.…”

Effects of annealing time on the structure and optical properties of ZnAl2O4/ZnO prepared via citrate sol-gel process

“…From the preparation point of view, the formation of ZnAl 2 O 4 spinel has been obtained by different routes, such as co-precipitation [11], modified citrate [12], microwave-hydrothermal [13], solid-state reaction [14], hydrothermal [15], sol-gel [16] and polymeric precursor [17]. Compared with the traditional methods, the sol-gel route offers the advantages such as good stoichiometric control, high homogeneity, producing nanostructured powders and thin films, as well as low temperature processing [9].…”

Luminescence switch of Mn-Doped ZnAl2O4 powder with temperature

“…Over the past decades, many applications for ZnAl 2 O 4 spinel compounds have been reported, such as catalysis of hydrocarbon reactions, 1,2 sintering of alumina ceramics, 3 or improving ceramic dielectric properties. 4,5 With an energy gap of 3.8 eV, this material is also an ultraviolet absorbent and is already used in optoelectronic devices.…”
