摘要: 为了提升堇青石-莫来石质匣钵的性能,以堇青石、莫来石M60和板状刚玉为主要原料,引入滑石粉、广西白泥、活性氧化铝,经1 345 ℃保温4 h原位反应合成了堇青石-莫来石质匣钵材料。研究了滑石粉的加入量(加入质量分数分别为0、2%、4%、6%、8%、10%)对材料力学性能和抗侵蚀性能的影响。结果表明:随着滑石粉加入量的增加,试样的体积密度提高,显气孔率下降,常温抗折强度提高;当滑石粉加入量为10%(w)时,制备的匣钵试样综合性能最佳,其显气孔率、体积密度和常温抗折强度分别为26.0%、2.18 g·cm-3、20.6 MPa,抗热震性良好,与未添加滑石粉的试样相比,力学性能显著提升,且具备良好的抗高镍三元正极前驱体侵蚀能力。

Abstract: To improve the performance of cordierite-mullite-based saggers,cordierite-mullite saggers were fabricated via in-situ reaction at 1 345 ℃ for 4 h using cordierite,mullite M60,and tabular corundum as the primary raw materials,and introducing talc powder,Guangxi white clay,and reactive alumina.The effects of talc powder additions (0,2%,4%,6%,8%,and 10%,by mass) on the mechanical properties and corrosion resistance of the saggers were systematically investigated.The results indicate that with the increasing talc powder addition,the bulk density of the samples improves,the apparent porosity decreases,the cold modulus of rupture improves.When the talc powder addition reaches 10%,the sagger exhibits the optimal overall performance,with apparent porosity of 26.0%,bulk density of 2.18 g·cm-3,cold modulus of rupture of 20.6 MPa,and favorable thermal shock resistance.Compared to the talc-free sample,the mechanical properties are significantly improved,and the sagger demonstrates excellent corrosion resistance to high-nickel ternary cathode precursors.
