Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a material having both of high hot strength-high corrosion resistance and thermal shock resistance and attaining high durability in a rebonded magnesia-chromium based brick.SOLUTION: The magnesia-chromium based brick is obtained by adding a binder to a raw material composition prepared by adding a ferrochromium alloy and chromium oxide to a refractory raw material aggregate containing electro-melt magnesia-chromium clinker as a main raw material and kneading the mixture to obtain a body, and molding and firing the body.
