A tungsten-precursor composite having a polymer matrix and a tungsten
precursor therein. The tungsten precursor may be tungsten oxide, ammonium
paratungstate, ammonium metatungstate or other precursor or combination of
tungsten precursors. The polymer may be any of a very wide range of
materials or combinations thereof. Binder, secondary fillers or other
third components may be added. By means of use of various tungsten
precursors, polymers, and third components, the physical, radiological and
electrical properties of the finished products may be tailored to achieve
desired properties. In addition, the invention teaches that radiation
shielding, insulators, and combined radiation shield/insulators may be
fashioned from the composite. A wide range of production methods may be
employed, including but not limited to liquid resin casting.
