PROBLEM TO BE SOLVED: To provide a refractory for lining of various industrial furnaces necessitating high corrosion resistance, which has excellent corrosion resistance to molten slag and spalling resistance. SOLUTION: The yttria refractory is obtained by blending so that Y<SB>2</SB>O<SB>3</SB>is contained in an amount of≥60 and≤99.9 wt.% and the balance is composed of one or more kinds of oxide among Al<SB>2</SB>O<SB>3</SB>, CeO<SB>2</SB>, ZrO<SB>2</SB>and MgO, then kneading the resulting mixture, forming, drying and firing at a high temperature.
