Decomposition of lead nitrate in nitrate melts in the presence of titanium dioxideThe interaction between titania and lead nitrate has been studied in molten sodium and potessium nitrates medium. The formation of tetragonal lead metatitanate has been established. The rate of the formation and the ...
The main chemical reactions occurring during lead smelting can be grouped in oxidation, reduction, decomposition, and roast reactions. 2.3.1.1.5.1 Oxidation (2.3.3)PbS+32O2=PbO+SO2 (2.3.4)ZnS+32O2=ZnO+SO2 (2.3.5)FeS+32O2=FeO+SO2 (2.3.6)PbS+2O2=PbSO4 (2.3.7)2PbS+72O2=PbO·PbSO4...
The thermal decomposition of lead nitrate has been investigated in the temperature range from 250 to 435掳C. Information obtained from the infra-red analysis of the decomposition products indicate that the reaction proceeds via a basic nitrate or metallic nitrite structure, while gasometric analysis ...
Thermogravimetric analysis of lead nitrate without and with added cupric oxide, managanese dioxide and alumina (20 wt.%) were done. The parameters of activation were calculated using the coats-Redfern equation. Al 2 O 3 and MnO 2 decreased the energy of activation, while CuO caused an ...

A new approach to the decomposition of nitrate ion using Pb metal has been developed. Removal of the oxide layer formed on the surface of Pb plate and the production of Pb powder have been achieved by in situ abrasion of Pb plate in NH4NO3 solution with an abrasive buff. NO3− was ...
Thermal decomposition of lead bromate has been studied in the temperature range 170-190deg C. The decomposition curves proceed through (i) short induction period, (ii) acceleratory and (iii) decay stages. Both acceleratory and decay stages follow Prout-Tompkins equation. Irradiation enhances ...
The thermal decomposition of unirradiated and 纬-irradiated lead nitrate was studied by the gas evolution method. The decomposition proceeds through initial gas evolution, a short induction period, an acceleratory stage and a decay stage. The acceleratory and decay stages follow the Avrami-Erofeyev...
The thermal decomposition of γ-irradiated lead nitrate was studied by thermogravimetry (non-isothermal conditions). The reaction order, activation energy, frequency factor and entropy of activation were computed by means of the Coats-Redfern, Freeman-Carroll, Horowitz-Metzger and the modified Horowitz-...
