Hydrothermal preparation of some strontium silicates

Hydrothermal Preparation and Characterization of Ultralong Strontium-Substituted Hydroxyapatite Whiskers Using Acetamide as Homogeneous Precipitation Reagent

The ultralong strontium- (Sr-) substituted hydroxyapatite (SrHAp) whiskers were successfully prepared using acetamide as homogeneous precipitation reagent. The effect of the Sr substitution amount on the lattice constants and proliferation of human osteoblast cells (MG-63) was further investigated. The results showed that the SrHAp whiskers with diameter of 0.2-12 μm and ultralong length up to ...

Ion-pair formation in aqueous strontium chloride and strontium hydroxide solutions under hydrothermal conditions by AC conductivity measurements.

Frequency-dependent electrical conductivities of solutions of aqueous strontium hydroxide and strontium chloride have been measured from T = 295 K to T = 625 K at p = 20 MPa, over a very wide range of ionic strength (3 × 10(-5) to 0.2 mol kg(-1)), using a high-precision flow AC conductivity instrument. Experimental values for the concentration-dependent equivalent conductivity, Λ, of the two el...

High-yield preparation of titanium dioxide nanostructures by hydrothermal conditions.

The effect of the neutral surfactant dodecylamine and octadecylamine on the synthesis of TiO2-based nanostructures by the treatment of anatase with NaOH under hydrothermal conditions in the temperature range 120-150 degrees C and different reaction times was investigated. The products analyzed by electron microscopy, X-ray diffraction, FT-IR and elemental analysis contains--depending of the ami...

Hydrothermal preparation and optical properties of ZnO nanorods

In the present paper, ZnO nanorods with the mean size of 50 nm× 250 nm were successfully synthesized via a hydrothermal synthesis route in the presence of cetyltrimethylammonium bromide (CTAB). ZnCl2 and KOH were used as the starting materials and zinc oxide nanorods were obtained at 120 ◦C for 5 h. The product was characterized by means of X-ray powder diffraction (XRD), transmission electron ...
