refining of osmium

Submitted by admin on Fri, 06/14/2019 - 01:34

Refining of osmium refers to the process of refining impurities in the crude crucible to produce pure rhodium in the platinum group metal refining process. It is composed of two stages of purification and purification of the absorbing liquid and preparation of the metal ruthenium, and the former is often more important.refining of osmium,osmium

what is Ruthenium

Yttrium metal

Submitted by admin on Tue, 06/11/2019 - 02:39

Yttrium (element symbol Y) is a heavy rare earth metal element. Yttrium is an important heavy rare earth metal because its physical and chemical properties are similar to those of other rare earth metals and often coexist with rare earth minerals of other rare earth metals. Yttrium metal has many applications in non-ferrous alloys, steel, rare earth permanent magnets and military industry. The application of iron and steel is as follows:
