| 摘 要： | 研究了富铝尖晶石的反应烧结特性，评价了这种特性对抗渣性能的作用，结果表明，富铝尖晶石的烧结主要受尖晶石内延长机理和晶界迁移所制约，但条件改变，可调整机制，避免笼络气孔形成，尖晶石愈富铝，晶格常数，热膨胀率愈小，这些都与尖晶石熟料及铝一类晶石烧注抗渣性有密切关系。

| Abstract: | The particular sintering mechanism of rich-alumina MgAl 2O 4 and its effect on slag resistance are described. The sintering of rich-alumina MgAl 2O 4 is controlled largely by internal growth and grain boundary mobility. If the conditions are improved, the mechanism is modified without cage-pore. The richer alumina MgAl 2O 4 is, the less the lat tice constants and thermal coefficient of expansion are. All of them influence the slag resistances of spinel clinker and its castable refractory. |
