Porous molybdenum particle reinforced glass matrix composites fabricated by microwave processing

Microwave-assisted densification was used to fabricate porous borosilicate glass matrix composites containing spherical porosity and molybdenum particle inclusions. The inverse thermal gradient typical of microwave heating and the presence of Mo particles led to the development of a layered porous structure of the compacts, consisting of a highly porous core and a relatively dense outer shell. Such a layered porosity was not obtained in glass compacts without Mo particles.
