Sol–gel method for preparing high surface area CoAl2O4 and Al2O3–CoAl2O4 spinels

Lattice strain estimation for CoAl2O4 nano particles using Williamson-Hall analysis

“…Preparation of CoAl 2 O 4 [12][13][14][15][16][17][18] was developed using different methods that can provide many advantages such as ability to control homogeneity, purity of the sample, relatively low temperature proseccing, size and shape controle as well as distribution of ceramic particles which overcoming traditional methods.…”

The environmentally benign synthesis of nanosized CoxZn1−xAl2O4 blue pigments

“…Recently, a polymeric precursor method involving citric acid and ethylene-glycol was used to obtain cobalt(II)-aluminates containing a reduced amount of cobalt [23]. Although low temperature synthesis of CoAl 2 O 4 oxide aluminates (temperatures starting from 450 C) have been reported, no information about their coloration properties has been provided [12,22]. A common temperature for the synthesis of the bluecolored CoAl 2 O 4 pigment is >800 C [16].…”

Synthesis and characterization of spinel-type CuAl2O4 nanocrystalline by modified sol–gel method

“…They are commonly used in semiconductor and sensor technology as well as in heterogeneous catalysis [23][24][25][26][27][28][29][30][31]. A modified solgel method for preparing the metal oxides is Pechini method [32].…”
