Gallium 
By Benjamin Petkof1 
  359 
 The domestic gallium industry continued to provide a significant portion
of U.S. demand although gallium imports increased in 1978 and 1979. Data
on world production and consumption were not available. Gallium was consumed
for the production of various gallium compounds used to produce electronic
devices. 
 Legislation and Government Programs.—.New tariff rates for imported
gallium metal and compounds resulted from the 1979 Tokyo round of tariff
negotiations giving most nations "most-favored nation" status.
The tariffs
for these nations will decline annually, in stages, beginning January 1,
1980 and ending January 1, 1987.

DOMESTIC PRODUCTION 
 The Aluminum Co. of America, using proprietary technology at its Bauxite,
Ark., alumina plant, recovered gallium as a coproduct from residues of its
alumina production process. Eagle-Picher Industries, Inc., produced gallium
metal, oxide, and 
trichloride from zinc production residues at its Quapaw, Okla., facility.
Production data are not available. Based on consumption and import data,
total domestic output was thought to have declined in 1978 and 1979. 
CONSUMPTION 
 Gallium consumption was strong in 1978 and 1979 and was above that of 1977.
The electronics industry had the greatest domand for high-purity material
to fabricate light-emitting diodes, semiconductors, and other electronic
devices. Small quantities of metal were used to prepare specialty alloys
and in research and development. Gallium oxide was used for the preparation
of phosphors. 
 General acceptance by the public of van 
ous electronic devices that use galliumbased components helped sustain gallium
demand. Continued interest in the development of gallium-based direct solar
energyconversion cells for the production of electricity and further development
of fiberoptic light-transmission cables actuated by gallium-based light-emitting
diodes, may stimulate demand for gallium and gallium compounds in the near
future.
