Nano BaSO4 prepared by microreactor and its effect on thermal decomposition of some energetics

The positive correlation between the dispersion and catalytic performance of Fe2O3 nanoparticles in nano-Fe2O3–ultrafine AP energetic composites supported by solid UV-vis spectroscopy

“…Thus, ultrafine AP and nano-Fe 2 O 3 have high purity, and there is no change in XRD diffraction peaks caused by excess impurities during the refining process. 24,26,35 where D is the particle size, B is the diffraction peak width at half maximum (rad), λ is the incident X-ray wavelength (0.15406 nm), and θ is the diffraction angle.…”

“…These conclusions are consistent with the results of the difference equation, which confirms the accuracy and feasibility of the difference equation. 1,22–24,41–44…”

“…The application of such nanocatalytic materials can also considerably improve the performance of propellants by increasing the burning rate, reducing the pressure index, adjusting and improving the ballistic properties, improving the energy performance, and reducing the characteristic signal of the propellants. 1,6,[18][19][20][21][22][23][24][25] However, the different catalysts mentioned exert different catalytic effects on AP. Nanocarbon materials can act as reducing agents to react with AP and release more heat; however, their catalytic ability for the thermal decomposition of AP is weaker than that of nanometals or nanometal oxides.…”

Spontaneous formation of barium sulfate crystals at liquid–liquid interfaces

“…[10][11][12][13][14] Barium sulfate (BaSO 4 ) is a well-characterised inorganic scale, known as both a synthetic and mineral (barite) compound with a rich morphology, [15][16][17] excellent physical properties and good chemical stability. 18 According to the group of Putnis, 19 crystallisation of BaSO 4 occurs through a non-classical mechanism, whereby smaller particles grow through oriented attachment. Homogenous nucleation and growth of BaSO 4 has been investigated by morphological and chemical structural analysis.…”
