Modification of the Structural, Textural, and Mechanical Properties of an Al2O3/Al Composite on the Addition of an Al-SBA-15-Type Mesoporous Phase

The formation of the pore structure of metal-ceramic materials based on Al2O3/Al composites has been studied in detail by modifying them via the incorporation of SBA-15-type mesoporous materials. The composition, pore structure, pore size, and morphology of the composite particles have been studied using nitrogen adsorption/desorption isotherms, scanning electron microscopy, and X-ray diffraction. We have produced Al-SBA-15/Al2O3/Al monoliths that combine properties of both adsorbents and permeable materials, but the incorporation of Al-SBA-15 into an Al2O3/Al matrix reduces the permeability and mechanical strength of the composites.
