Modified steel slag-based solar selective absorption heat collection and storage ceramic particle and preparation method thereof
The invention discloses a modified steel slag-based solar selective absorption heat collection and storage ceramic particle and a preparation method thereof, and the modified steel slag-based solar selective absorption heat collection and storage ceramic particle is prepared from the following raw materials in percentage by mass: 40-80 wt% of steel slag, 15-25 wt% of aluminum oxide, 5-18 wt% of ferric oxide, 0-7 wt% of manganese dioxide and 0-10 wt% of titanium dioxide. The raw material powder is uniformly mixed, molded, calcined at high temperature and the like to obtain the heat collection and storage ceramic particles for solar tower-type thermal power generation. The solid ceramic particles prepared by the method have the characteristic of low infrared band emission while realizing efficient absorption of solar radiation, and are stable in performance at high temperature and lower in cost.
本发明公开了一种改性钢渣基太阳能选择性吸收集储热陶瓷颗粒及其制备方法，按照质量百分比，其原料由以下组分组成：钢渣40‑80wt%、三氧化二铝15‑25wt%、三氧化二铁5‑18wt%、二氧化锰0‑7wt%、二氧化钛0‑10wt%。上述原料粉末经过混合均匀、成型、高温煅烧等工艺即可得到太阳能塔式热发电用集储热陶瓷颗粒。本发明制备的固体陶瓷颗粒在实现太阳辐射高效吸收的同时兼具红外波段低发射的特点，且高温下性能稳定、成本更低。
