TLDR
In this paper, the structure of NASICON type ceramics has been investigated for a fixed sintering cycle and it has been shown that the more elements introduced by means of metal-organic reagents, the more shifted structural evolution towards monoclinic structure to high temperatures.About:

Conductivity Measurements on Nasicon and Nasicon-modified materials
TL;DR: In this paper, the authors investigated the variation of the ionic conductivity as a function of the composition x is investigated in the temperature range 150-600 K. They showed that the variations of ionic motion process in the bulk of the material can be explained by structural considerations, and that the mobility of the Na+ ions in these materials seems to be mostly influenced by the size of the bottlenecks through which the ions have to pass.

Glasses from metal alcoholates
Sumio Sakka,Kanichi Kamiya +1 more
TL;DR: In this paper, the technique of preparing oxide glasses from metal alcoholates through hydrolysis, gelling and heating at low temperatures has been reviewed, which makes it possible to produce very high purity and compositions which the conventional melting technique could not give because of immiscibility, crystallization and high melting temperatures.
