interest in shaft smelting has resulted in the design and construction of a 
laboratory shaft furnace in which they have studied the extraction of nickel. 
During 1952 to 1955, they completed the design of a thermocouple for use in 
temperature control of hot steel in ladles and furnaces. 
Ferrites have received considerable attention at the Institute, 
especially the reduction of iron, cobalt, and nickel ferrites by hydrogen 
and graphite, and the effect of additives, such as the alkali carbonates. 
They have also been active in semiconductor research, including better methods 
of determining selenium and tellurium and investigations of vanadium 
pentoxide systems for possible use as semiconductor materials, 
Their Analytical Laboratory cooperates with various groups by 
doing spectral and chemical analyses of metals they have produced. 
They have investigated the feasibility of using oxygen in metal- 
lurgical furnaces and the effects of vacuum in the processing of nonferrous 
metals. 
The Institute irregularly publishes a Trudy.
