Material type selective radiator and preparation method thereof
The invention relates to a material type selective radiator and a preparation method thereof. The radiator is made of cobalt-based spinel structure ceramic, the chemical component expression is CoMxN2-xO4, M and N are one or more of Al, Fe, Cr or Ga, and x is larger than or equal to 0 and smaller than or equal to 2. Raw material powder containing Co, M and N elements is mixed in proportion, ball-milled, dried and then put into a muffle furnace for presintering, presintered powder is ground, sieved and tabletted, and finally the selective radiation material with excellent performance is prepared through high-temperature sintering. The radiator has the advantages of being high in spectral efficiency, resistant to high temperature, resistant to oxidation, resistant to thermal shock and the like, efficient thermoluminescence conversion of different heat sources can be achieved, the structure of a thermophotovoltaic system can be simplified, and the system efficiency can be remarkably improved.
本发明涉及一种材料型选择性辐射器及其制备方法。所述辐射器材料为钴基尖晶石结构陶瓷，化学组分表达式为CoMxN2‑xO4，其中M和N均为Al、Fe、Cr或Ga中的一种或几种，0≤x≤2。将含Co、M、N元素的原料粉料按比例混合、球磨、干燥后放入马弗炉中预烧，预烧粉经研磨、过筛后进行压片，最后经高温烧结制得性能优异的选择性辐射材料。本发明所述的辐射器具有光谱效率高、耐高温、抗氧化和抗热冲击等优点，能实现对不同热源的高效热释光转换，可简化热光伏系统结构并显著提高系统效率。
