Abstract
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.
