Ceramic oxyanion emitter
Patent
·
OSTI ID:215236
A rare earth oxide matrix (composition of matter) is formed which emits (upon heating) heavy metal oxide anions (oxyanions) into a gas phase, wherein the anions are emitted with high intensity, and wherein longevity of life of the composition of matter is retained. The matter is formed by blending a major component of a rare earth oxide, europium oxide (Eu{sub 2}O{sub 3}) or ytterbium oxide (Yb{sub 2}O{sub 3}), with a minor component of a barium (Ba), calcium (Ca) or strontium (Sr) salt of a heavy metal oxyanion. Heavy anions are emitted upon heating the composition of matter to a predetermined temperature of about 800 C.
