 Abstract GA and GA-based alloys have recently been studied as liquid metals, LMS, with the advantageous combination of low toxicity, low melting point, high fluidity, and high conductivity. One way to modify these LMS for improved processability and novel applications is through the use of colloidal micro droplets suspended in a liquid medium. In this study, the authors investigated the vitrification behavior of oil-based colloidal systems containing suspended LM droplets with added mineral oxide, MO, nanoparticles. The MOs were found to have a strong affinity for the surfaces of the LM droplets, resulting in a highly viscous fluid at low MO concentrations. This effect was further enhanced when higher MO concentrations were used, leading to a highly viscous emulsion with a yield stress of approximately 104 pascals. These results suggest that the addition of MOs can lead to the formation of highly vitrified emulsions with improved thermophysical properties, making them suitable for a variety of applications.
