Stabilization/solidification of waste ferrous sulphate from titanium dioxide Production by fluidized bed Combustion Product.
Waste Management, 2001Co-Authors: Milan Vondruska, Vratislav Bednarik, Mari SildAbstract:A treatment procedure to allow the disposal of waste ferrous sulphate was developed. This waste contains sulphuric acid and originates from titanium dioxide Production. The process is based on simultaneous neutralization and stabilization/solidification (S/S) of the waste by means of fluidized bed Combustion Product (FBC-P). The prepared stabilized waste specimens have a solid matrix and their batch leachates display practically neutral pH and also satisfactory conductivity values. The leachate composition is notable in its absence of toxic metals and even iron.

synthesis of nanocrystalline magnesium aluminate mgal2o4 spinel powder by the urea formaldehyde polymer gel Combustion route
Materials Research Bulletin, 2009Co-Authors: K Prabhakaran, D S Patil, Rajiv Dayal, N M Gokhale, S C SharmaAbstract:Abstract Nanocrystalline MgAl 2 O 4 spinel powder was synthesized by the urea–formaldehyde (UF) polymer gel Combustion route. A transparent gel formed from magnesium nitrate, aluminium nitrate and UF after drying underwet self-sustained Combustion when initiated with a burning splinter. The Combustion Product on calcinations at 850 °C formed MgAl 2 O 4 spinel. Calcination of the Combustion Product resulted in particle coarsening. The powder obtained by planetary ball milling of the spinel had a median particle size of 1.58 μm. The spinel particles are agglomerates of nanocrystallites of size in the range 10–30 nm. The compacts prepared by uni-axial pressing of the spinel powder sintered to >99% TD at 1600 °C.

synthesis of nanocrystalline yttria doped ceria powder by urea formaldehyde polymer gel auto Combustion process
Materials Research Bulletin, 2007Co-Authors: Mridula Biswas, K Prabhakaran, N M Gokhale, S C SharmaAbstract:Abstract Nanocrystalline yttria doped ceria powder has been prepared by auto-Combustion of a transparent gel formed by heating an aqueous acidic solution containing methylol urea, urea, cerium(III) nitrate and yttrium(III) nitrate. The TGA and DSC studies showed the Combustion reaction of the gel initiated at 225 °C and completed within a short period of time. XRD spectrum of the Combustion Product reveals the formation of phase pure cubic yttria doped ceria during the Combustion process. Loose agglomerate of yttria doped ceria particle obtained by the Combustion reaction could be easily deagglomerated by planetary ball milling and the powder obtained contains particles in the size range of 0.05–3.3 μm with D 50 value of 0.13 μm. The powder particles are aggregate of nanocrystallites with a wide size range of 14–105 nm. Pellets prepared by pressing the yttria doped ceria powder sintered to 95.2% TD at 1400 °C.
