Abstract: PROBLEM TO BE SOLVED: To obtain a refractory, excellent in corrosion and heat spalling resistances by adding and mixing a specific amount of an aqueous solution binder of magnesium chromate with a refractory composition containing a magnesia-based raw material and a chromia-based raw material and forming and drying the resultant mixture. SOLUTION: This refractory is obtained by using 0.5-6 pts.wt. aqueous solution binder of magnesium chromate based on 100 pts.wt. refractory composition containing a magnesia-based raw material and a chromia-based raw material. The aqueous solution of the magnesium chromate is preferably the one having 1.2-1.7 specific gravity. One or more selected from a baked product or an electrofused product of a natural raw material or an artificial raw material can be used as the magnesia-based raw material. A chrome mineral, chromium oxide or a magnesia-chrome clinker can be used as the chromia-based raw material. Magensium sulfate, magnesium chloride, magnesium acetate, a phenol resin and the like may be used as the binder in combination besides the magnesium chromate.  Thereby, the drying can be carried out at low temperatures and excellent strength characteristics are ensured in a high-temperature region to improve the durability.
