Übersetzung für "Elemental impurities" in Deutsch

I am especially pleased to see that AGC's elemental impurities are often below the detection limit of a GDMS technique.

To ensure product quality and process optimization, the determination of elemental impurities is crucial for control labs in refineries and in the production of alternative fuels.

In addition, the binding phase may also contain impurities, for example carbon, metallic impurities, elemental boron, borides, boron carbide or other carbides such as, for example, silicon carbide.

The average of these two results is 0.7135 ppm of total re gistered elemental impurities (please refer to Table 1 below, under the subheading 'Coosa Purified Concentrate Average (ppm)'), yielding a combined average 99.99993 wt % C ("6N3") purity.

Further, the accompanying elemental/mineral impurities analysis on more than 75 elements represents the most comprehensive report to date on AGC's purified graphite material — our feedstock to produce our sourced-and-made-in-USA ULTRACSPGTM battery-ready graphite.

In the context of expanding globalization, it is becoming increasingly important to adequately control elemental impurities in medicinal products in order to avoid hazards to patients caused by toxic substances in medicines.

Coosa purified concentrate sample number one recorded a combined total of 1.135 ppm of registered elemental impurities (please refer to Table 1 below, under the subheading 'Coosa Purified Concentrate Sample No. 1 (ppm)'), yielding a purity measurement of 99.9999 wt % C ("6N") .

The first series of analytic testing determined elemental concentrations of impurities using inductively coupled plasma optical emission spectrometry ("ICP-OES"), which confirmed the ultra-high purity of AGC's graphite.

These elements are often impurities of the pigments or their synthesis.

The alloy can contain between 0.1 and 1.0 weight per cent of alloying elements and/or impurities.

The resulting acidic solution requires several steps to precipitate the dissolved element impurities from solution.

The sinking crystals receive less of the alloying element and impurities than the melt as a result of which there is a negatively segregated region at the base of the ingot and a positive region at the top.

Furthermore, such melts should not have any elements or impurities or should not be able to disseminate any elements or impurities to the silicon, i.e., elements or impurities which could be considered to be lifetime killers for the minority carriers in silicon.

The quartz sand used contains a number of different elements as impurities, among them the alkaline metals K and Li at 0.5 ppm and Na at 0.6 ppm.

It is an object of the present invention to provide a process for obtaining platinum of high purity from a platinum alloy, in which platinum can be separated from the other alloy elements and metal impurities present to obtain platinum having a purity of 99.95% with simple equipment, in a short period of time, with minimal losses, reduced labor and without addition of expensive chemical substances.

Moreover, the composition indicated can also contain minimal impurities with less than 0.5 atomic percent of each impurity element.

Melts of this type should also not contain, nor deposit on the silicon, any elements or impurities which could be regarded as lifetime-killers for the minority carriers in silicon.

For use in making components which are required to have a very high resistance to uniform corrosion and against pitting and crevice corrosion under very highly corrosive conditions encountered in up to date chemical process technology and environmental protection technology, for instance, in flue gas desulfurizing plants for concentrating sulfuric acid, and which are required to be manufactured satisfactorily by conventional hot and cold forming processes an alloy is employed which contains (in % by weight) 22.0 to 24.0 chromium, 15.0 to 16.5 molybdenum, up to 0.3% tungsten, up to 1.5% iron, up to 0.4% vanadium, 0.1 to 0.4% aluminum, 0.001 to 0.04% magnesium and 0.001 to 0.01 calcium, balance nickel and inevitable accompanying elements and impurities.
