Nanostructured AgPb18SbS20 compound synthesized by hydrothermal method

Materials Letters, 2013
Abstract Nanostructured AgPb 18 SbS 20 thermoelectric powders have been successfully synthesized by hydrothermal method. X-ray diffraction (XRD) and transmission electron microscopy (TEM) were respectively used for characterization of the powders. The mean size of the powders synthesized at 180 °C for 48 h is about 300 nm.

Obtaining aluminosilicate refractories by the hydrothermal method

Refractories, 1967
On the basis of aluminosilicate bond made from heat-processed hydrated alumina and quartz sand in the molecular ratio of Al2O3: SiO2=3∩2, in conditions of autoclave processing at 800–1000 kg/cm2 in a period of 8–12 h, it is possible to obtain unfired aluminosilicate refractories with quite high physico-chemical factors.

Preparation of Titanate Nanotubes by Hydrothermal Method

Materials Science Forum, 2009
Titanate nanotubes have been directly prepared by hydrothermally treating P25 powders in NaOH aqueous solution. Effect of calcination temperature on crystal phase, morphologies and specific surface area of the as-synthesized nanotubes has been investigated in detail. The Na2Ti3O7 tubular structure could be kept well even after calcination at 600 °C and

Synthesis of Zirconium Tungstate by Hydrothermal Method

Advanced Materials Research, 2011
Negative thermal expansion material ZrW2O8 was synthesized by hydrothermal method. The prepared ZrW2O8 and the precursor were characterized by x-ray diffractometer, thermo-gravimetric/differential thermal analyzer, FT-IR spectrometer and scanning electron microscope.

Synthesis of gadolinium silicate by hydrothermal method

AIP Conference Proceedings, 2013
A simple method based on hydrothermal synthesis of materials to prepare gadolinium silicate has been prescribed. It is found that molar ratio of Gd(NO3)3: TEOS plays a crucial role in the formation of Gd2SiO5. The effect of calcinations, concentration of the precipitating agent and dopant atoms on composition and morphology of the synthesized materials

Evolutionary optimisation method for multistorage hydrothermal scheduling

IEE Proceedings - Generation, Transmission and Distribution, 2002
An evolutionary method is proposed for minimising the operational cost in the scheduling of hydrothermal systems with multiple storage. The method combines the advantages of constructive dynamic programming and evolutionary programming. Instead of evolving the primal variables such as water releases and thermal generator outputs, it evolves the ...

ZnWO??? luminescent films obtained by hydrothermal method

2017
ZnWO??? films of 10???20 ??m thickness can be produced by hydrothermal synthesis method without additional subsequent treatment. The data obtained show that films possess wolframite structure and demonstrate luminescent properties which are similar to bulk ZnWO???.
