The preparation and characterization of Hong and von Alpen types of Nasicons are described. When highly reactive gel‐processed powders are heated at about 1000°C, Nasicons are formed in a finely divided state. Sintering of compacts requires 1125° to 1325°C, depending on the composition. Observed sintering kinetics suggest a liquid‐phase mechanism; SEM reveals the Hong Nasicons to contain two (when zirconia‐free) or three phases. The von Alpen materials are zirconia‐free, but consist of two phases. A glass phase is common to both materials, and its presence is attributed to the liquid‐phase sintering mechanism.
