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 ...
Their interaction involves formation of certain formaldehydes, peroxides, peroxyacyl nitrate, etc. which cause eye irritation, plant damage, and contribute to poor visibility. Present day gasoline contains lead, added to raise its octane number. 98.8 per cent gasoline sold in the world market today...
The PL emission properties from pure perovskites are closely related to their underlying crystal structures and trap states. Enhanced crystallinity should reduce bulk and surface defects, suppressing non-radiative exciton recombination and enhancing PL emission34,35. The data presented here, on the other...
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 ...
ChemInform Abstract: The Effect of γ-Irradiation on the Thermal Decomposition of Lead Nitratereactions (including homogeneous catalysis)lead, Pbnitrogen, Nis investigated using the gas evolution method.doi:10.1002/chin.198840024NAIR, S. M. K....
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 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 ...
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-...
The effect of 纬-irradiation on the thermal decomposition of Pb(NO3)2 has been studied by the gas evolution method. Irradiation enhances the decomposition rate, the effect increasing with dose. Post-irradiation annealing tends to restore the decomposition characteristics of the original unirradiated ...
A Raman and IR spectrophotomeric study of some basic lead nitrate compounds and their thermal decomposition productsdoi:10.1016/0022-1902(76)80231-XThe IR and Raman spectra of the compounds usually formulated as PbO·Pb(NO3)2·2H2O, 3PbO·Pb(NO3)2·3H2O and 3PbO·H2O have been studied. ...
