【Abstract】 The effect of three kinds of Fe₂O₃ additives on properties of periclase-spinel materials has been researched.The results show that all the additives could improve the materials’ mechanical properties,thermal stability resistance and stickability to kiln coating.Instead of magnesia-chrome brick burnt in a cement kiln,using the pericalse_spinel brick with Fe₂O₃ may solve chrome polluted problem.更多还原
