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
