Journal ArticleDOI
Non-linearity in rare earth doped zinc oxide varistor prepared by flash combustion method
TL;DR: In this paper, a flash combustion technique involving flash combustion of nitrate-urea mixtures has been reported for praseodymium doped zinc oxide containing K2O in the range 0·0-0·5 mol%.
Journal ArticleDOI
Effect of silver and palladium on dye-removal characteristics of anatase-titania nanotubes.
TL;DR: It has been shown that silver-deposited anatase-titania nanotubes are more effective in enhancing the kinetics of the dye-removal via surface-adsorption and photocatalytic degradation mechanisms relative to the palladium-deposit-and-recovery method.
Journal ArticleDOI
Temperature assisted acid catalyzed peptization of TiO2; facile sol–gel approach for thermally stable anatase phase
Vidya Kattoor,Venu Sreekala Smitha,A. Peer Mohamed,Unnikrishnan Nair Saraswathy Hareesh,Krishna Gopakumar Warrier +4 more
TL;DR: In this article, temperature assisted acid catalyzed peptization of hydrous titania through an aqueous sol-gel method has been successfully synthesized by phase pure anatase to rutile phase transformation by 200 °C.
Journal ArticleDOI
Surface modification of kaolinite by controlled thermal treatment
TL;DR: In this paper, a method based on thermal decomposition-hydration-redecomposition treatment similar to the one reported by Petro et al. has been used with a sample of high kaolinitic Kerala china clay.
Journal ArticleDOI
Aqueous extrusion of alumina–Zirconia (12 mol% ceria) composite using boehmite as extrusion aid
C. Sunil Kumar,Unnikrishnan Nair Saraswathy Hareesh,B. C. Pai,A. D. Damodaran,Krishna Gopakumar Warrier +4 more
TL;DR: In this paper, a higher order of homogeneity of the constituent phases has been achieved by controlling the pH of flocculation at 8.5 and sintering was carried out at 1600°C.
