Introduction to Ammonia Production - AIChE

Haber finally developed a process for producing commercial quan-tities of ammonia, and in 1906 he was able to achieve a 6% ammonia concentration in a reactor loaded with an osmium catalyst. This is generally recognized as the turning point in the development of a practical process for the production of ammonia in commercial quantities.

GOLD

Gold is the most malleable and ductile of all metals; a single gram can be beaten into a sheet of 1 square meter, or an ounce into 300 square feet. Gold leaf can be beaten thin enough to become translucent. The transmitted light appears greenish blue, because gold strongly reflects yellow and red. [2] Such semi-transparent sheets also strongly reflect infrared light, making them …

What are the Uses of Transition Metals? - Science Struck

Iridium and Osmium. Both elements were discovered as by-products when platinum was first extracted from its ores. Iridium is mainly used to manufacture high-temperature laser crystals, and a platinum-iridium bar is used as the standard measure of a kilogram. Osmium, on the other hand, is a hard metal that is resistant to wear and tear.
