摘要: Perovskite-type BaSnO3 powders with a particle size of 30–60 nm have been prepared from tin oxide hydrate (SnO2 · xH2O) gel via the hydrothermal synthesis route. The reactivity synthesized SnO2 xH2O was found to be dependent on pH value mixture chloride and ammonia solution. most reactive obtained at near 2. products derived this were characterized thermograrimetric/differential thermal analysis, Fourier transform infrared spectrometry, X-ray diffraction high-resolution scanning electron microscopy. BaSn(OH)6 phase in as-prepared powder convert into an amorphous other than phase. crystallizing 260°C for 4 h has better sintering properties commercial one.
