Description: 
The majority of research and development work conducted by Giredmet 
is aimed at improving processes for separating the rare earths and for pro- 
ducing the individual rare-earth metals. Past investigations have resulted 
in improved methods of producing high-purity rhenium and gallium, concentrat- 
ing scandium, and purifying antimony and thallium by recrystallization. 
Reports emanating from the Institute indicate an interest in the 
Chokhral'skiy method for pulling single crystals. Several investigations 
dealt with the effect of this method on crystal-structure dislocations in 
silicon single crystals. In addition, the Institute's Design Office has 
developed an electric vacuum furnace for use in producing crystals by the 
Chokhral'skiy method. 
The Spectral Laboratory has done extensive work on the development 
and introduction of high-speed methods for studying the rare metals. They 
have concentrated on the analysis of the difficult-to-determine elements 
(rare earths, selenium, scandium, germanium, zirconium, rhenium, etc.) using 
spectroscopic and spectrophotometric methods. 
The Institute also provides samples of various rare-earth metals to 
industrial and research laboratories for experimental purposes. 
In 1961, a cooperative venture was conducted for the design of 
transducers for use in autopilot equipment for river craft.
