Aorthite heat storage ceramic prepared from magnesium slag and preparation method thereof
The invention relates to the technical field of energy storage materials, in particular to anorthite heat storage ceramic prepared from magnesium slag and a preparation method thereof. The anorthite heat storage ceramic is prepared from the following raw materials in percentage by mass: 32-60% of magnesium slag, 25-56% of kaolin, 0-12% of corundum and 0-15% of fluxing agent, and the sum of all the raw materials is 100%. The anorthite phase with good high-temperature thermal stability is synthesized from the magnesium slag, the prepared heat storage ceramic is free of cracking after 30 times of thermal shock cycles (from 800 DEG C to room temperature), the maximum volume density reaches 2.36 g.cm <-3 >, the maximum breaking strength reaches 71.72 MPa, the heat storage density can reach 800-900 kJ/kg (from room temperature to 800 DEG C), the performance requirements of heat storage materials in various heat storage technologies can be met, the raw material cost is low, and the preparation process is simple, easy to adjust and convenient for industrial production.
本发明涉及储能材料的技术领域，具体涉及一种利用镁渣制备的钙长石储热陶瓷及其制备方法，按照质量百分数计，包括以下原料：镁渣32wt％～60wt％、高岭土25wt％～56wt％、刚玉0～12wt％、助熔剂0～15wt％，所有原料的总和为100wt％。本发明利用镁渣合成高温热稳定性能良好的钙长石相，制备的储热陶瓷经过30次热震循环(800℃～室温)后无开裂，体积密度最高达2.36g·cm‑3，抗折强度最高达71.72MPa，储热密度可达800～900kJ/kg(室温～800℃)，可满足各种储热技术中储热材料的性能要求，且原料成本低，制备工艺简单，易于调节，便于工业化生产。
