Thermal shock resistant heat storage ball
The invention relates to the technical field of alumina refractory products, in particular to a thermal shock resistant heat storage ball, and magnesium aluminate spinel (MgAl2O4) is the only intermediate compound in a MgO-Al2O3 binary system. The MgAl2O4 crystal is of an octahedral structure, Mg < 2 + > accounts for the tetrahedral position, Al < 3 + > accounts for the octahedral position, the content of an Al2O3 crystal phase without ignition loss is higher than 60wt%, the content of an MgAl2O4 crystal phase is higher than 30wt%, the magnesium aluminate spinel heat storage ball prepared from the MgAl2O4 crystal is fine and smooth in texture and ideal in heat storage and heat release, the thermal shock resistance stability reaches more than 40 times, and the thermal shock fatigue resistance upper limit of the heat storage ball is greatly prolonged.
本发明涉及氧化铝耐火材料制品技术领域，尤其涉及抗热震蓄热球，镁铝尖晶石(MgAl2O4)是MgO‑Al2O3二元系中唯一的中间化合物。MgAl2O4晶体呈八面体结构，其中Mg2+占四面体位置，Al3+占八面体位置，除去烧失量后的Al2O3晶相高于60wt%,MgAl2O4晶相高于30wt%，由此作为原料制作的镁铝尖晶石蓄热球，质地细腻，蓄热放热理想，抗热震稳定性达到40次以上，极大的延长了蓄热球的抗热震疲劳上限。
