摘　　要：利用高碱铝铬渣和轻烧镁砂合成镁铝铬尖晶石，同时，Ｎａ２Ｏ和Ｋ２Ｏ在高温下挥发，显著降低了合成料中的碱含量。MgO·(Al,Cr) 2O 3 spinel was synthesized from active magnesia and chromium slag containing Al 2O 3,Cr 2O 3,Na 2O and K 2O.As Na 2O and K 2O were evaporable at high temperature,the soda content in the synthesized material decreased significantly.

关 键 词：铝铬渣 尖晶石 合成 耐火材料
