| Research Abstract |
New solar concentration systems of "post heating system" and "cross linear system" were developed, and highly reactive ceramics YSZ/Ni-ferrite solid solution was synthesized. TheαO_2 releasing reaction by rapid heating proceeds via two steps of 1) photon absorption and its relaxation process forming an excess Frenkel structure(light reaction), and 2) O_2 gas formation from lattice oxygen, which is driven by defect structure energy(dark reaction). The dual column solar reactor(3_<rd> model) was fabricated, with which the light and dark reactions can be occurred continuously. The field test of the rotary reactor developed was done at the solar field of CSIRO.
