Alloy-coated ceramic-based high-temperature heat storage material and preparation method thereof
The invention discloses a ceramic-based high-temperature heat storage material wrapped with an alloy. The ceramic-based high-temperature heat storage material comprises a ceramic matrix with a filling space and the alloy packaged in the ceramic matrix, wherein the alloy is a Cu-Si alloy. The sensible heat storage characteristic of ceramic is utilized, and the high-temperature phase change latent heat storage performance of the Cu-Si alloy is exerted, so that the alloy-coated ceramic-based heat storage material not only has higher heat storage density, but also shows better thermal shock resistance and high-temperature resistance, has longer high-temperature service life, and can be used for heat storage of the Cu-Si alloy. And the performance requirement of the tower type solar thermal power generation high-temperature heat storage material is met.
本发明公开了一种包裹合金的陶瓷基高温储热材料，该陶瓷基高温储热材料包括具有填充空间的陶瓷基体以及封装在陶瓷基体内的合金；其中，所述合金为Cu‑Si合金。本发明利用了陶瓷的显热储热特性，并发挥了Cu‑Si合金的高温相变潜热储热性能，使得包裹合金的陶瓷基储热材料不但具有较高的储热密度，而且表现出较优的抗热震性和耐高温性，具有较长的高温服役寿命，满足塔式太阳能热发电高温储热材料的性能要求。
