 An important new material for solar photovoltaic cells promised to cut the
cost and improve the efficiency of these devices. Developed by Energy Conversion
Devices, Inc., of Troy, Mich., the main structure of the cell consisted of
doped and undoped layers of amorphous silicon and fluorinecompounds, which
together act as a semiconductor. Such layers could also be used for other
semiconducting applications." 46 
 Dolibid, an aspirin substitute containing fluorine compounds, after being
discovered in the United States, was test marketed in the United Kingdom
in April 1978.~~ 
 Foote Mineral Co., of Jenkintown, Pa., announced its new lithia-containing
flux for use in steelmaking. The product, called Footespar, is a metallurgical
fluorspar substitute. 
 New geologic data on New Mexico's fluorspar districts and specific deposits,
along with developments and discoveries since 1966, was presented in a publication
by the New Mexico Bureau of Mines and Mineral Resources.48 
 A report on the Bayhorse fluorite deposit in Custer County, Idaho, was published.
The deposit had a measured reserve of 73.2 million short tons grading 36%
CaF,. The deposit was formed as an open space, filling in collapse breccia
features of the Ordovician Bayhorse Dolomite. Mineralization was probably
related to the Eocene Challis Volcanic Series." 
 An artificial blood substitute called Fluosol was sucessfully used in life-saving
blood transfusions. The fluorine-based compound could prove invaluable for
disaster victims, battlefield casualties, patients with rare blood types,
and patients whose religious beliefs prohibit normal blood transfusions.'°
