Sentence examples for mg diffusion from inspiring English sources

The growth process is controlled by Mg diffusion to SiO2 substrate.

We applied the addition of both SiC and liquid aromatic hydrocarbon to the internal Mg diffusion (IMD) processed MgB2 wires.

It is observed that, similar to the bulk, Mg diffusion in absence of vacancies is energetically prohibitive.

These changes were presumably due to the onset of phase separation of the Zn0.7Mg0.3O barrier layers with pronounced Mg diffusion toward the ZnO wells.

In particular, for high Mg concentrations, a stage of absolute instability dependent on the Mg diffusion effect but independent of the Zn concentration happens.

In present work, the kinetics mechanism of reaction between Mg and B forming MgB2 layer in the internal Mg diffusion (IMD) processed MgB2 wires were systemically studied in present work.

As the reaction processes and the thickness of synthesized MgB2 layer increases, the slow Mg diffusion-limited mechanism gradually becomes dominant at final stage.

Microstructural characterization of AIMI MgB2 wires before and after the heat treatment reveals that the reaction mechanism changes from a "Mg infiltration-reaction" at the beginning of the heat treatment to a "Mg diffusion-reaction" once a dense MgB2 layer is formed.

As Fe-Mg diffusion in silicates is generally fast, SiC could not survive at adiabatic temperatures in the mantle for any reasonable time span (i.e. >100'000 yrs) hence precluding any high temperature (>1000°C) origin of natural moissanite.

Calculated Fe-Mg diffusion lengths reveal that SiC grains of 1 mm would react with the Fe-component of olivine to iron carbide or metal and orthopyroxene within <1 Ma at temperatures above 800°C.

Taking a putative SiC grain in a matrix of otherwise undisturbed mantle silicates, Fe-Mg diffusion coefficients of the silicates allow for calculation of the time-temperature conditions for which a given grain size of SiC would react with olivine until its complete destruction.
