Title     The preparation of erbium oxide high-temperature ceramic and its emissivity research
Abstract
Thermalphotovoltaic (TPV) ,which is a new type of thermoelectric conversion device, has the advantages of high energy conversion efficiency, wide energy source, high reliability and no pollution. but the low actual efficiency has become one of the major factors limiting its development. As a key component of the thermal photovoltaic power generation system, the performance of selective emitters has a great influence on overall system efficiency. Erbium oxide high-temperature ceramic is a kind of materials well matched with gallium antimonide (GaSb) thermal photovoltaic cells. This paper mainly studies the preparation method of high temperature resistant ceramic based on erbium oxide,and synthesize qualified Erbium oxide high-temperature ceramic using the method of solid phase synthesis after compounding, mixing, granulation, pressure molding and sintering steps . Meanwhile ,the paper measeures thermal radiation characteristics of erbium oxide ceramic samples, obtains their spectral emissivity and explore the effect of the different erbium oxide content and alumina fiber content on selective radiation characteristics of the sample.
Keywords： Thermal photovoltaic Selective emitter Erbium oxide Ceramics
