Tin ingots'physical appearance may bethe same but impurity levels are different.
2.
However, given the usual impurity levels, the reaction frequencies are negligible.
3.
The highest impurity levels reached are not uncommon in some classroom or office environments.
4.
Impurity levels, most often low, may influence the measurements.
5.
Since rain comes from clouds-it's hard to imagine how there would be any difference in the impurity level.
6.
This velocity is a characteristic of the material and a strong function of doping or impurity levels and temperature.
7.
Generally, it is possible to assess material's crystalline quality, local stress / strain, dopant and impurity levels and surface temperature.
8.
Some biological substrates are very sensitive to heat and may have fast decomposition rates that are not favored and yield larger impurity levels.
9.
Impurity levels of a few parts per million had previously been considered excellent; Pfann's technique improved on this by factors of over 1, 000 . ".
10.
There are advanced refining processes such as the Czochralski process than can be used to reduce impurity levels to below the C10100 specification by reducing copper grain density.
