These results indicate a reduction in the oxidation state of iron (with decreasing oxide content), as a new phase of iron (Fe3C) and silica emerged.
A number of shrouding systems have been developed to minimize oxidation to enable production of low oxide content coatings while spraying in air.
Conversely, lipid peroxidation (TBARS), nitric oxide content, and gluthathione reductase activity were significantly higher, indicating an increase in oxidative stress.
Only earth with an aluminum oxide content of 30 percent or more is considered practical.
A low iron oxide content is also essential, since oxygen and sulfur compete to combine with the calcium.
Very small differences in oxide content can drastically affect the final colour of a glass; yet colours and tints were reproduced time and again with remarkable consistency.
The limitation for fine particles is likely caused by the high oxide content.
Low oxide content and high bond strength densities can be achieved using this process [90].
These coatings can show low bond strength, high oxide content and high porosity.
Consequently, it is important to assure that oxide content of coatings be limited.
The oxide content and magnitude of the residual stresses were shown to be detrimental for adhesion.
