TL;DR: Silicon nitride has been researched intensively, largely in response to the challenge to develop internal combustion engines with hot-zone components made entirely from ceramics as mentioned in this paper, but this research effort has succeeded in generating a degree of understanding of silicon nitride and of its processing and properties.

TL;DR: The first NATO Advanced Study Institute on Nitrogen Ceramics held in 1976 at Canterbury came at a particularly significant moment in the development of this subject and reflected accurately the state of knowledge with respect to the basic science, the powder technology, and the prop erties of materials based on silicon nitride and associated syst ems.

TL;DR: In this article, the authors reviewed the literature concerning oxygen permeation and diffusion through amorphous and crystalline silicon dioxide, and silicate glasses, and collected data for diffusion coefficients to facilitate the assessment of probable dominant oxygen transport mechanisms, and associated rates.

TL;DR: In this article, a range of methods for the detection of barium carbonate contaminant in barium titanate powder has been assessed, namely: X-ray diffraction (XRD), scanning electron microscopy (SEM), with EDS-X-ray microanalysis, Fourier transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), gas chromatography (GC) for analysis of carbon.

TL;DR: In this paper, the authors reviewed the literature on the α/β silicon nitride transformation and concluded that α and β are probably low and high temperature forms of silicon oxide, respectively, and that the transformation occurs via a solution-precipitation mechanism.
