... by spark plasma sintering (SPS) at 1600°C for 10, 20 and 30 min. Subsequently, the samples were heated at 1350°C for 2 h to determine the influence of the excess Al 2 O 3 on the microstructure. No glassy phase was detected in the sample containing 72 wt.% Al 2 O 3 and sintered at 1600°C for 20 min...

...Jérémy Guignard; Misha Bystricky; Frédéric Béjina Abstract We have fabricated dense polyphase mixtures (silicate and oxide minerals, metal, and silicate melt) by Spark Plasma Sintering (SPS), a technique that has only recently been applied to silicates. We describe the SPS method and some...

... sintering compared to conventional sintering. Another type of sintering process is known as ‘spark plasma sintering’ (Gu et al., 2015 ), but its main drawback is that a temperature gradient is created in both the radial and axial directions, which causes cracks to appear. The sintering temperature...

Another field well represented at the meeting, and in this special issue, is that of elemental and isotopic...

Starting in 2006, cold sintering (e.g., spark plasma sintering) was applied to nanocrystalline apatites ( Drouet et al. 2006 , 2009 ; Grossin et al. 2010 ), pointing out the possibility to consolidate these compounds at low...
