Lightweight aluminum foams have a wide range of industries application as good energy and acoustic absorbers. The current state of the art with regards to the production of metallic foams is reviewed, with direct foaming of Al melt processing and a CaCO3 foaming agent used to generating lower material cost, a relatively low level of impurity presence, more uniform and finer cell structures to produce semi-industrial aluminum panel foams and consequently structure properties investigated. Calcium carbonate is found to be a highly effective foaming agent for aluminium and silicon carbide used to stabilise foam structure added to the aluminum molten so led to defects elimination, which result significant reduction in the thickness of melt drainage to achieve more uniform foams. Structure properties investigated at various thicknesses and cell sizes indicated that by enhancing the thicknesses and decreasing cell sizes caused improvement of Al-foam panels. Optical microstructure(OM) and cells distribution quality of samples measured and the cell size (Dm) calculated with image analyzer by microstructural image processing (MIP) software furthermore, scanning electron microscopy (SEM) images of SiC particles to evaluate two parameters of melt drainage and foam expansion as criterions the notable fall in large cavities subsequent uniform cellular which result in desirable distribution of SiC particles on interior surface of cells.
