Solar energy storage ceramic material with high energy storage density
The invention discloses a solar energy storage ceramic material with high energy storage density. The solar energy storage ceramic material is prepared from the following components in parts by weight: 60-80 parts of silicon nitride, 30-45 parts of boron nitride, 15-25 parts of boron carbide, 5-15 parts of titanium silicide, 5-12 parts of aluminum oxide, 2-7 parts of sodium silicate, 3-10 parts ofmagnesium oxide and 1-5 parts of lanthanum oxide, wherein all the components are powder with the average particle size of 10-50nm; silicon nitride, boron nitride and boron nitride are adopted as basematerials, so that the ceramic material has the advantages of being good in compressive strength and high in thermal shock resistance; and meanwhile, titanium silicide, aluminum oxide, sodium silicate, magnesium oxide and lanthanum oxide are added as additives, and especially a small amount of lanthanum oxide is added, so that the energy storage density of the ceramic material can be remarkably improved. The energy storage density of the solar energy storage ceramic material with high energy storage density can reach 1000 kJ/g or above.
本发明公开了一种高储能密度太阳能储能陶瓷材料，由以下重量份的成分组成：氮化硅60‑80份、氮化硼30‑45份、碳化硼15‑25份、硅化钛5‑15份、氧化铝5‑12份、硅酸钠2‑7份、氧化镁3‑10份和氧化镧1‑5份。以上各成分均为平均粒径10‑50nm的粉末；其中本发明采用氮化硅、氮化硼和氮化硼为基材，具有抗压强度为好，抗热震能力强的优点，同时加入硅化钛、氧化铝、硅酸钠、氧化镁和氧化镧为添加剂，尤其是加入少量的氧化镧可以显著提升陶瓷材料的储能密度。本发明的高储能密度太阳能储能陶瓷材料的储能密度可以达到1000 kJ/g以上。
