TLDR
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.Abstract:
Silicon dioxide and silicate glass films are formed on silicon nitride and silicon carbide ceramics during exposure to high-temperature oxidising atmospheres, and oxygen transport through the film is potentially a rate-controlling step. Recent published literature concerning oxygen permeation and diffusion through amorphous and crystalline silicon dioxide, and silicate glasses, is reviewed. Data for diffusion coefficients are collected to facilitate the assessment of probable dominant oxygen transport mechanisms, and associated rates, under given sets of oxidation conditions.read more

Silicon Nitride and Related Materials
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: A great deal of progress has been made in determining the equilibrium fractionations of 18O/16O, D/H, 13C/12C, and 34S/32S among fluid and mineral components at high temperatures (≥400°C), both from experimental exchange studies, theoretical calculations, semi-empirical calculations (using bond-type considerations), and empirical calibrations based on natural assemblages.

General Relationship for the Thermal Oxidation of Silicon
Bruce E. Deal,A.S. Grove +1 more
TL;DR: In this paper, the thermaloxidation kinetics of silicon are examined in detail based on a simple model of oxidation which takes into account the reactions occurring at the two boundaries of the oxide layer as well as the diffusion process, the general relationship x02+Ax0=B(t+τ) is derived.

Viscosity, Plasticity, and Diffusion as Examples of Absolute Reaction Rates
TL;DR: The theory of reaction rates yields an equation for absolute viscosity applicable to cases involving activation energies where the usual theory of energy transfer does not apply as mentioned in this paper, which provides an explanation of the law of rectilinear diameters of Cailletet and Mathias.
