In situ porous alumina/aluminum titanate ceramic composite prepared by spark plasma sintering from nanostructured powders

Reaction sintering of colloidal processed mixtures of sub-micrometric alumina and nano-titania

“…In particular, different authors have reported fine grained (grain size < 2.2 mm and d 50 $ 0.8 mm [7,14] and grain size d 50 $ 1.5 mm [20]) dense and uncracked composite materials with 5-20 vol% of aluminium titanate and porous materials with 30 vol% of aluminium titanate processed from nanostructured alumina-titania aggregates [21] have been reported.…”

Consolidation of hydrogenation–disproportionation–desorption–recombination processed Nd–Fe–B magnets by spark plasma sintering

“…Recently the spark plasma sintering (SPS) technique is widely used for sintering new kinds of materials especially to consolidate ultrafine grain [11], nanostructure [12] and nano-powders [13]. In the SPS process, pulsed electric current flows directly through the sintered materials, and generates local heating at the particle interfaces [13].…”

In situ nanostructured ceramic matrix composite coating prepared by reactive plasma spraying micro-sized Al–Fe2O3 composite powders

“…Such structure of the composite powders provides homogeneous distribution of Al and Fe 2 O 3 . Therefore, thermite reaction between Al and Fe 2 O 3 may be enhanced to prepare in situ composite with homogeneous composition distribution [23].…”
