Sentence examples for concentration of oxide from inspiring English sources
Calcination at 900 °C resulted in the formation of binuclear iron species and also enhanced the concentration of oxide phase.
The same trend is observed for propyne and methanol: (i) the amount of dissociated species increases with the relative concentration of oxide ions of low coordination OLC2−, (ii) MgLC2+ also are involved in deprotonation.
The defect chemistry of this system, which determines the electrical properties, is dominated by the high concentration of oxide vacancies necessary to stabilise the cubic structure, hence electronic conductivity exhibits a P(O2 -1/4 dependence on oxygen partial pressure.
X-ray photon electron spectroscopy (XPS) of direct cast wires showed that stable Cr/Si oxide were formed and the evaluation of experimental cast data suggest that a minimum concentration of oxide former is required to maintain continuity in wire products.
It has been shown that the redox activity inherent in molybdenum trioxide makes it possible the composite growing at low concentration of oxide in the plating solution (below 3 g L− 1) and ensures efficient overgrowing of the incorporated MoO3 nanoparticles with matrix metal.

In extreme cases, the concentration of oxides of iron leads to formation of a hard crust, in which case they are described as lateritic (for later, the Latin term meaning "brick") soils.
NMHCs play a significant role in ozone (O3) production in the presence of adequate concentration of oxides of nitrogen in the atmosphere.
In the case of aluminum alloys, the distribution and concentration of oxides on the alloy surface is determined by the heat treatment temperature and the bulk magnesium concentration of the alloy.
