Abstract A bulk metallic glass foam with a diameter of 8.1 mm and a length of 70 mm was fabricated by infiltrating Zr-based liquid metal into NaCl powder as a pattern in a few seconds and water quenching the pattern. Both the powders and the prealloyed charges were sealed in a U-turn quartz tube as a crucible and heated in two different temperature regions respectively in the electric resistance furnace. The sample fabricated is the largest in diameter up to now according to the literature. The X-ray diffraction and the scanning electron microscopy were used to check the amorphous nature and structure of the porous samples. The results show that the samples are consisted of amorphous phase and have good connectivity among the cells in the foam. The sizes of struts and the holes are largely smaller than 1mm. The density and porosity of the open-cellular bulk metallic glass are 3.63g/cm3 and 40.5% respectively. Porous bulk metallic glass is the most potential materials that will be used as biologic-transplant materials.
