The 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 purity of PbTiO_3 are determined by presence of the intermediate lead oxinitrates ...
14. These two mechanisms may lead to different soil C loss in a warmer world14,21. While the former could lead to a depletion of labile C pools, releasing more C into the atmosphere through microbial respiration if more plant-derived C is available...
SBET: specific surface area calculated using BET equation in a PP0−1 of 0.01–0.1. b Vtotal: total pore volume estimated at PP0−1 = 0.99. c Vmicro: micropore (0–2 nm) volume determined from NLDFT method. d Vmeso: mesopore (2–50 nm) volume determined from NLDFT method. e ...
It is well-known that global warming has effects on high-latitude tundra underlain with permafrost. This leads to a severe concern that decomposition of soil organic carbon (SOC) previously stored in this region, which accounts for about 50% of the world
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...
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 ...
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....
Spontaneous thermal decomposition of ammonium nitrate may lead to heat accumulation resulting in sudden rise of temperature, fire or even thermal explosion. In spite of the great progress made to date, disasters like that one in Toulouse (Grande Paroisse, 21 September 2001, France) or in Romania...
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 ...
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-...
