Born in Uman, now in the Cherkasy region of central Ukraine, Radzievsky left school in 1927 to work as a moulder in a silica plant in his home town of Uman.
One such class of catalyst systems, discovered and developed by the group of Jean-Marie Basset, comprises tantalum hydride supported on silica (SiO2)TaH at temperatures of 25°C to 200°C.
It also contains the following other ingredients: Dicalcium phosphate, microcrystalline cellulose, croscarmellose sodium, stearic acid, silica, magnesium stearate, and film coat (hypromellose, hydroxypropyl cellulose, polyethylene glycol, propylene glycol, titanium dioxide, FD&C yellow #6 lake, riboflavin, FD&C blue #2 lake).
There are various solid mineral deposits within state - industrial clay, silica, lignite, kaolin, tar sand, decorative rocks, limestone, etc.
BAE took over the US research company Armor Holdings who were doing research based on suspensions of silica particles.
The province possesses rich minerals and raw materials resources – Muruntau gold-bearing field, silica sand fields (of more than 1.5 billion tons), deposits of granite (1.9 billion cubic meters), marble (420 million cubic meters), phosphorites (1.5 billion tons) and many others.
