High-strength light spinel bubble brick for lithium ion battery positive electrode material production kiln and preparation method thereof
The invention relates to a high-strength light spinel bubble brick for a lithium battery positive electrode material production kiln. The high-strength light spinel bubble brick is prepared from the following components by weight: 56-65 parts of magnesium aluminate spinel hollow spheres, 35-44 parts of matrix powder and 2-6 parts of a sintering aid; in the magnesium aluminate spinel hollow spheres, the content of Al2O3 is greater than or equal to 68%, the content of MgO is greater than or equal to 29%, and the particle size is 0.2-5mm; the matrix powder is composed of rho-Al2O3 powder of 325 meshes and light calcined magnesia powder of 200 meshes according to a weight ratio of 1.85:1; the sintering aid is lanthanum cerium carbonate; the volume density of the magnesium aluminate light spinel bubble brick is designed to be 0.9-1.65g/cm<3>; and the prepared light magnesium aluminate spinel brick body has excellent erosion resistance, and the strength of the product is improved. The brickbody is used for building a kiln, erosion of the lithium ion positive electrode material can be effectively resisted, peeling is prevented while the service life is prolonged, the quality of the positive electrode material is improved, and the use cost is reduced.
一种用于锂电池正极材料生产窑炉用高强轻质尖晶石空心球砖，以重量计，砖体由56~65份的镁铝尖晶石空心球、35~44份的基质粉料以及2~6份的烧结助剂制成；镁铝尖晶石空心球中Al2O3≥68%、MgO≥29%，粒径为0.2~5mm；基质粉料为325目的ρ‑Al2O3粉和200目轻烧氧化镁粉以重量比1.85:1组成;烧结助剂为碳酸镧铈;设计镁铝轻质尖晶石空心球砖的体积密度为0.9~1.65g/cm3；制备的轻质镁铝尖晶石质砖体拥有优良的抗侵蚀性，提高了制品强度。将砖体用于搭建窑炉，能有效抵抗锂离子正极材料侵蚀，提高其使用寿命的同时防止剥落，提高正极材料质量，降低使用成本。
