The importance of chemical purity of metals

Without metals with a high degree of purity, researchers can not determine the true physical properties (or physics) of materials, which leads to missed opportunities in clarifying theoretical issues, discovering new alloys or developing devices.

The purity parameter is denoted by the Latin letters XN, where X is the digit indicating the presence of impurities and / or alloying elements in the metal composition. A doping component is a chemical element that improves the physical and mechanical properties of a metal, while an impurity deteriorates such indices. The chemical purity scale N (Nines) sets the content of impurities / dopants in percent per million (ppm).

Scale of chemical purity of metals

There are seven levels of chemical purity:

Thus, when the material is declared pure at 99.99% or 4N, the maximum number of other components can not exceed 0.01%. For example, in an ingot 4N pure tin (Sn) for each million atoms, 999,900 atoms will be tin atoms, and the remaining 100 atoms will be atoms of other elements (10 ppm impurity).

Company-supplier Avec Glob offers at affordable prices various metals and alloys in a wide range of brands and profiles. The supplier guarantees the timely delivery of products to any address specified by the consumer.

Certificates of chemical purity

There are absolute purity and purity of the base metal. The metal base, as is usually indicated in the catalogs, does not include many of the metallurgically important intermediate elements or other non-metallic impurities. For example, in the manganese analysis certificate (Mn), where 99.95% purity is indicated, it can simultaneously be reported that manganese contains 0.3% oxygen. Hence, the actual chemical purity of manganese can not be higher than 99.65%. When determining the purity of metals, chemical elements such as H, B, C, N, O, F, Si, P, S, Cl, As, Se, Br, Te, I, At are not taken into account. Since some of them may be impurities, the true concentration of foreign particles is unknown.

The quality of the certificate of chemical purity N is determined by the industry in which the metal is used. For the use of metals in the semiconductor industry, the characteristics of N are usually stiffer than for general engineering.
