Disperse fine equiaxed α-Al2O3 nanoparticles with narrow size distribution are important materials in nanotechnology and nanomaterials, but syntheses of disperse usually result γ-Al2O3 or large larger than 15 nm. has a higher surface energy becomes thermodynamically not stable respect to at specific areas 100 m(2)/g (at sizes smaller nm for spherical particles) room temperature. So extremely difficult synthesise. Here we show the successful synthesis average below 10 by selective corrosion...
Nanocrystalline microstructure is regarded as a strategic approach to overcome the brittleness of alumina ceramics, and preparation disperse equiaxed α‐Al 2 O 3 nanoparticles an essential step for nanocrystalline ceramics. In this work, were prepared using α‐Fe seed isolation phase. At first, composite embedded in matrix was obtained by calcining precursor powder containing γ‐Al OOH Fe( OH ) (Fe 3+ /Al mole ratio 5) at 770°C h. Then with mean size 12 nm distribution from 40 without...
Mechanochemical synthesis is a promising method for studying the size-dependent melting of metals if size resulting metallic nanoparticles can be tuned effectively. Here, with Cu as an example, we show that tuning particle sizes accomplished by extending milling time at high speed and following annealing milled samples. With so prepared samples, point depression its dependence are successfully investigated.
