PURPOSE:To obtain an inexpensively producible heat accumulating material of ceramics with slight restriction of manufacturing condition by blending an iron ore containing a specific amount of iron with a molding sintering auxiliary, an organic additive, etc., and burning. CONSTITUTION:100 pts.wt. iron ore (50-80wt.% iron content) is blended with 0.1-40 pts.wt. one or both of (A) a molding sintering auxiliary (e.g. feldspar, clay or frit) and (B) an organic additive (e.g. acrylic acid-based polymer) (preferably <=5 pts.wt. component B), molded and burnt at 650-1,500 deg.C to give a heat accumulating material of ceramics. |
