Temperature-dependent thermal properties of spark plasma sintered alumina

Autor: Saheb Nouari, Hayat Umer

Publikováno v: Science of Sintering, Vol 49, Iss 2, Pp 117-128 (2017)

In this work, we report temperature-dependent thermal properties of alumina powder and bulk alumina consolidated by spark plasma sintering method. The properties were measured between room temperature and 250ºC using a thermal constants analyzer.
