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 ...
Carry out the replacement reaction for cooper removal at the condition of around 50℃.At this time, the solubility of the nitrate lead is 44% while the cooper content in the lead nitrate solution is about 0.025%. According to the Nernst equation, the replacement reaction can be carried out ...
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...
biochemical oxygen demand (BOD), nitrite and nitrate, PO43–-P, DO, electrical conductivity (EC), turbidity, total suspended solids (TSS), volatile suspended solids (VSS), total dissolved solids (TDS), total Kjeldahl nitrogen (TKN), SO42−, ...
In addition to U, the plume contained high concentrations of nitrate (~ 1 g l−1) and sulfate (~ 2 g l−1). A 12-m saturated zone was contaminated by the plume, which was moving at an average rate of 15 m year−1. Oxidation of sulfides, resulting in generation of acid pore...
Further, the experimental data were used to confirm the pore diffusion as one of the rate-controlling steps using Bangham's equation. The graph obtained [Fig. 6(e)] using Bangham's equation was found to be linear with a quite good correlation coefficient R2 = 0.958 indicating ...
Decomposition temperature no data available pH no data available Kinematic viscosity Viscosity of molten lead: 3.2 cP at 327.4 deg C; 2.32 cP at 400 deg C; 1.54 cP at 600 deg C; 1.23 cP at 800 deg C Solubility Insoluble (NTP, 1992) ...
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 ...

Decomposition of lead azide (LA), pentaerythrite tetranitrate (PETN), and a laminate system composed of these substances under vibrational loading is considered. Sensitivity of these substances to impact and vibrations is determined. Sensitivity of the LA + PETN laminate system to vibrational loading...
