Additive-free hot-pressed silicon carbide ceramics-A material with exceptional mechanical properties

Additive-free hot-pressed silicon carbide ceramics-A material with exceptional mechanical properties P. Šajgalík, J. Sedláček, Z. Lenčéš, J. Dusza, H.-T. Lin Abstract Densification of silicon carbide without any sintering aids by hot-pressing and rapid hot pressing was investigated. Full density (>99% t.d.) has been reached at 1850 °C, a temperature of at least 150–200 °C lower compared to… Continue reading Additive-free hot-pressed silicon carbide ceramics-A material with exceptional mechanical properties

Spark plasma sintering of zirconia/nano-nickel composites

Spark plasma sintering of zirconia/nano-nickel composites Carlos F. Gutierrez-Gonzalez, Nestor W. Solis Pinargote, Said Agouram,Pavel Y. Peretyagin, Sonia Lopez-Esteban and Ramon Torrecillas Abstract This work describes a whole processing route for obtaining dense and nanostructured zirconia-nickel composites with low contents of metallic phase (1–3.5 vol%). For the processing route, a combinationof spray-freezing and lyophilization has… Continue reading Spark plasma sintering of zirconia/nano-nickel composites
