WebThe present invention relates to a method for manufacturing a metal-oxide-based ceramic, including, in order, the step of inserting, into a flash sintering device, a nanocrystalline powder comprising crystallites and crystallite agglomerates of a ceramic of formula, Zr1-xMxO2, where M is chosen from yttrium, scandium and cerium, or Ce1-xM′xO2 ... WebJan 22, 2007 · The width of the G peak exceeds 50 cm − 1 in all cases, revealing that the size, La, of the graphite crystallites is around or lower than 1 nm [9]. In this range of crystallite size, it has been demonstrated that the intensity ratio varies according to the relation [10]: (1) I D I G = c · L a 2 with c equal to around 0.0055 (for La in Angstrom).
