  • METHOD FOR PRODUCING ALUMINUM COMPOSITE MATERIAL
    Publication number: 20150119229
    Abstract: Provided is a method of producing an aluminum composite material, the method including: a decalcification treatment step of eluting a calcium oxide component from cement to form decalcified cement having a reduced content of the calcium oxide component; and an aluminum oxide formation step of bringing molten aluminum into contact with the decalcified cement to replace, among metal oxide components contained in the decalcified cement, metal oxide components other than the calcium oxide component, in particular, a silicon dioxide component, with aluminum oxide.
