ABSTRACT:
A process and an apparatus for producing a composite of a particulate inorganic material, such as Shirasu balloons, and a metal, such as aluminum, in four inventive aspects. The composite is produced successively by the process steps comprising charging a mold cavity of a mold with the particulate inorganic material to form an aggregation of the particles, injecting a molten metal into the aggregation through a molten metal permeable refractory partition wall from a molten metal storage vessel, forwarding the resulting aggregation impregnated with the molten metal, cooling the impregnated aggregation to solidify and taking the solidified molded composite out of the mold. The composite according to the present invention is stout, light weighing, non-inflammable and easily processible and exhibits high dimensional stability and uniform distribution of the material properties, so that it can be used for construction and architecture purposes.
