The role of the synthesis route to obtain densified TiO2-doped alumina ceramics

Citrate–nitrate auto-combustion synthesis of perovskite-type nanopowders: A systematic approach

“…10,11 Citrate-nitrate auto-combustion synthesis (CNA) is a very popular solution combustion method, [12][13][14] where the fuel is citric acid and metal nitrates are used as metal and oxidant source. CNA method shows high similarities with the very well known Pechini process 15,16 and it can be more properly described as a "sol-gel combustion method". 17 Nevertheless the CNA method differs from Pechini process in that the nitrates are not previously eliminated as NOx, but remain in the mixture with metal citrates causing the auto-combustion.…”

Alumina–titania ceramics prepared by microwave sintering and conventional pressure-less sintering

“…gas separation, biomedical processes, support for transition metal catalyst, electronic and optical applications [1][2][3][4][5]. It was also reported that addition of titania to alumina considerably changed its sintering behaviour to manufacture dense ceramics [6,7]. In addition, the fracture toughness and wear resistance of alumina was improved with dispersion of titania [8,9].…”

Preparation of nanostructured Al2O3–TiO2 composite films by MOCVD

“…Plasma spraying has been the most common preparation method to attain thick-enough Al 2 O 3 -TiO 2 composite coatings, which have been improved by supplying the individual components in nanometric sizes [9][10]. The deposition of TiO 2 on nanozised powders of Al 2 O 3 or alternatively, the formation of Al 2 O 3 -TiO 2 nanocomposite powders have been investigated by the sol-gel method over the last decade [11][12]. The synthesis of Al 2 O 3 -TiO 2 composite films by using the chemical vapor deposition (CVD) method has been more recent [13][14].…”
