On the condition of laboratory, the optimal process of Cu-Fe composite powder prepared is as follows: the amount of iron powder (about 0.053 mm) is 20g, 20 ml HCl solution (1%, V/V) is used to wash the powder for about 3 min and 100 ml CuSO4 solution (0.4 mol/L) is used in the laboratory,the agitating velocity was slow or medium.
The powder exhibits good dispersion of Mo and Cu ingredients and high sinterability. A relative density of 99.65% is achieved for Mo-Cu composites sintered at 1150 ℃ for 90 min in H2 atmosphere. Furthermore,the prepared Mo-Cu materials show good physical and mechanical properties.
The density of the TiAl alloy with near-full density obtained by hot-pressing sintering at 1 300 ℃ from the powder milled for 40 h is 3.971 g/cm3.Homogeneous microstructure of TiAl-based alloys with fine grains is obtained.
X-ray powder diffraction results show that the as-grown SrWO4 single crystal belongs to tetragonal system and I41/a space group.
The structures of the CdSe quantum dots were determined by X-ray powder diffraction (XRD) and transmission electron microscopy (TEM).
Tungsten trioxide powder has been prepared from ammonium paratungstate via hydrothermal method using orthogonal and mono-level design of experiments.
The blank reference experiment shows that hydrothermal crystallization treatment favors the formation of hexagonal tungsten trioxide, and the tungsten trioxide powder sample prepared by this method has a high degree of crystallinity.
According to the Ullman reaction mechanism, the synthesis of 1,5-di(o-anisidino)anthraquinone was achieved by the multiphase reaction of 1,5-dichloroanthraquinone in xylene and o-anisidine in the presence of copper metal powder and potassium acetate.
Chemical and physical reactions during the low temperature aqueous chemical synthesis of nanostructured Bi2Te3 powders were investigated in-situ by pH measurement, color observation of the solution and X-ray diffraction analysis of the powders.
Preparation and characterization of ZrWMoO8 powders with different morphologies
ZrWMoO8 powders with different morphologies were obtained using ammonium tungstate, molybdate tungstate and zirconium tungstate as the starting materials by dehydrating the precursor ZrWMoO7(OH)2(H2O)2.
TEM photographs of synthesized powders from the sol-gel auto-combustion showed that the crystallites were uniform in size.
The magnesium powders used in the fabrication process include nanometer-sized magnesium particles, powders from Alfa Aesar, ordinary off-the-shelf powder, and magnesium chip.
The mechanical treatment of a number of powder metals (Al, Ni, Fe, Cu, Ag, and W) was investigated.
