Syntheses and characterization of Sr(OH)2 and SrCO3 nanostructures by ultrasonic method

Abstract

The Sr(OH)(2) and SrCO(3) nanostructures were synthesized by reaction of strontium(II) acetate and sodium hydroxide or tetramethylammonium hydroxide (TMAH) via ultrasonic method. Reaction conditions, such as the concentration of the Sr(2+) ion, aging time, power of the ultrasonic device and alkali salts show important roles in the size, morphology and growth process of the final products. The pure crystalline SrCO(3) were obtained by heating of product at 400 degrees C. The Sr(OH)(2) and SrCO(3) nanostructures were characterized by scanning electron microscopy (SEM), X-ray powder diffraction (XRD), thermal gravimetric (TG), differential thermal analyses (DTA) and the infrared spectroscopy (IR).

Chemical and structural stability of La0.6Sr0.4Co0.2Fe0.8O3− ceramic vs. medium/high water vapor pressure

“…A strong narrow peak at $ 859 cm À 1 can be assigned to the out-of-the-plane bending (υ 2 ) mode, and that observed at $ 1071 cm À 1 to the fully symmetric stretching (υ 1 ) mode of CO 2 À 3 ions. The absorption bands characteristic of Sr (OH) 2 , and SrCO 3 observed here are similar to those presented in the literature [59,60].…”

Biomimetic Synthesis and Antibacterial Properties of Strontium Oxide Nanoparticles Using Ocimum Sanctum Leaf Extract

“…4 , and 3383.14 cm −1 can be assigned to O-H bending and C-O is stretching vibrations [27]. The O-H and C-O stretching bonds of the FTIR spectrum is very similar to our previously reported FTIR spectrum of OS leaf extract [23].…”

Alkaline-Earth Metal Carbonate, Hydroxide and Oxide Nano-Crystals Synthesis Methods, Size and Morphologies Consideration

“…15b shows the top view of the hexagonal cone, from which one can clearly see the six crystal planes [104]. Nanostructures of the mixture of Sr(OH) 2 and SrCO 3 were prepared by sonochemical method [106]. Our search shows that there is no report for synthesis of Sr(OH) 2 nanostructures and this is the first report.…”
