An ingot of AZ91D alloy was placed above the hollow spheres separated by a 2 mm thick layer of zirconia felt (Zircar Zirconia Inc. Florida NY USA). The felt was used as a reaction barrier between the magnesium alloy melt and the spheres prior to infiltration and served as a filter to remove the oxide layer from the liquid melt.
