The Development of Pore-Free Ceramics

摘要: In the early 1950s techniques and understanding previously used only to study microstructure of metals began be applied polycrystalline oxides (which about that time called ceramics). Sintering is a phenomenon interest both fields, development sintering science provided bridge between physical metallurgy newly developing ceramics. The application ceramics mechanisms grain growth in soon led production pore-free alumina yttria. A critical step was prevention discontinuous by reduction boundary mobility with additions magnesia thoria Some discussion how these additives operate presented new mechanism proposed.
