This book explores new experimental phase diagrams of non-oxide ceramics, with a particular focus on the silicon nitride, silicon carbide and aluminum nitride, as well as the ultra-high temperature ceramic (UHTC) systems. It features more than 80 experimental phase diagrams of these non-oxide ceramics, including three phase diagrams of UHTC systems, constructed by the authors. Physical chemistry data covering the period since the 1970s, collected by the author Z.K.Huang, is presented in si...
