A key step in the processing of ceramics is the consolidation of powders into engineered shapes. Colloidal processing uses solvents (usually water) and dispersants to break up powder agglomerates in suspension and thereby reduce the pore size in a consolidated compact. However, agglomeration and particle rearrangement leading to pore enlargement can still occur during drying. Therefore, it is b...

It is important to consider the thermal management of lithium-ion batteries overcome their limitations in usage and improve performance life cycles. In this study, a novel cooling system for battery packs proposed by using an inner cylinder channel different-shaped nanoparticles base fluid, which used as medium. The improvements 20 Ah capacity are compared water–boehmite alumina (AlOOH) nanoflu...

Citric acid added as set retarder significantly contributed to enhancing the setting temperature and to extending the thickening time of a calcium aluminate phosphate (CaP) geothermal cement slurry consisting of calcium aluminate cement (CAC) as the base reactant and sodium polyphosphate (NaP) solution as the acid reactant. The set-retarding activity of citric acid was due to the uptake of Ca2'...

A gas phase, probe molecule doser was fabricated and connected to a diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) reaction chamber study the reactions stability of two organosilanes with surfaces metallic aluminum boehmite powders in situ. Two powder were studied, including an as-received, native oxide layer surface, laboratory prepared, boehmite-like surface. Neat also u...

The influence of NaNO2, HNO3 and H2SO4 on the structure and morphology of gamma-alumina was investigated by XRD, BET, SEM and FT-IR spectroscopy. Selected amounts of NaNO2, HNO3 and H2SO4 were added to a solution of aluminum isopropoxide (as a precursor for the boehmite synthesis). The boehmite samples were calcined at 350 and 600 ℃ to form the semi-crystalline high surface area gamma-Al2O3. Th...
