摘要
储热陶瓷是确保能源连续稳定供应的关键材料.研究以硅藻土和贝壳为原料,采用无压固相烧结法研制了硅藻土-贝壳陶瓷储热材料,采用XRF、XRD、SEM等测试技术研究 了硅藻土-贝壳对储热陶瓷材料组成、结构与性能影响的关系规律.结果表明,硅藻土和贝壳粉的质量配比为60:40的经1 220 ℃烧成的A4配方样品,储热密度达956.1 kJ/kg(室温～800 ℃),抗折强度为73.72 MPa,体积密度为2.48 g/cm3,气孔率为0.96％及吸水率为0.40％,具有优良的物理性能和储热性能,可望用做高温服役的储热陶瓷材料.
Abstract
Thermal storage ceramic materials are the key to ensure the continuous and stable power supply.thermal storage ceramics were prepared via pressureless sintering method by using diatomite and sea shell as the raw materials.The phase composition,microstructure and properties of the thermal storage ceramics were tested by XRF,XRD,SEM and so on.The results showed that A4(60％diatomite,40％sea shell)sintered at 1 220 ℃ exhibited the optimum proper-ties,the the thermal storage density,bending strength,bulk density,apparent porosityand water absorption reached 956.1 kJ/kg(RT～800 ℃),73.72 MPa,2.48 g/cm3,0.96％and 0.40％,respectively.This study supports the thermal storage ceramics as a promising temperature thermal storage candidate.
