High Purity Metals: Function And Industrial Applications

New technologies are constantly reshaping how fabrication shops do business. Manufacturers are consistently expecting innovation and the application of new processes and materials to produce better results. They want preciseness combined with cost-effectiveness delivered in the deal package to meet their specifications and needs. When it comes to the area of advanced technologies, companies demand materials that feature the optimum properties, the highest qualities and impeccable performance. For fabricators, researchers, developers and manufacturers this requires employing high purity metals.

Processes for Producing High or Ultra Purity Metals

These metals are earth metals and are classified according to their purity. This purity is a characteristic or quality measured according to two scales: absolute purity and metals basis purity. Their utility in a number of applications is achieved through their creation by fabrication shops into a variety of shapes and designs using diverse methods and techniques. Among the most common ones are:

Atomization: Diverse methods utilize this method. Among them are gas, centrifugal, plasma and water atomization

* Mechanical attrition and alloying

* Melt spinning

* Rotating electrode process (REP)


In all methods, the onus is on the right application by the fabricator and his or her shop of a thin layer or film coating of high purity metals over the substrate or subsequent layer (s). The result is a part or product that must be proficient in achieving the stated goal of the customer. It must be capable of meeting the stringent demands of the customer and government organizations and regulations.

Applications of High Purity Metals

The demand for this particular grade of metal is high in a number of areas. In particular, those in research and development, as well as those in advanced technology production seek it. They are looking for materials that deliver excellent magnetic, superb thermoelectric, exceptional phosphor and outstanding semiconducting qualities. They need the resulting products to be able to withstand high temperatures as well as exhibit heightened magnetic aptitudes. In other words, they require only what high earth metals can give them.

The resulting products provide a lengthy list with more waiting to emerge from the R & D labs. Among the most common ones are:

* Advanced ceramics – including multi-layer ceramic capacitators

* Compact fluorescent lighting (phosphors)

* Electronic sensors

* High-precision lenses

* High quality optics

* Lasers

* LEDs

* Neutron radiography

* Plasma TV screens

* Super alloys

* Thermal barrier coatings

Whenever the products – as those listed above, demand precision and specific qualities in order to function optimally, fabricators, researchers, developers and manufacturers contend the only answer is to employ high purity metals.
