TI  - FABRICATION OF UNDERCOOLED BISMUTH TIN LIQUID METAL PARTICLES WITH HIGH YIELD
AB  - Despite increasing attention to the liquid metals, most of the studies in this field havefocused on the gallium-based alloys due to their low melting points. The examples of metastableundercooled liquid metal particles are rare due to the thermodynamic challenges in achieving significantlevel of undercooling. In this study, the fabrication of undercooled bismuth-tin (BiSn) liquid metal micro-/nano-particles at eutectic composition was studied. The droplet emulsion technique was used for particleformation in broad size range. The effects of the particle size and the shell formation reactions on the yieldof undercooled particles were investigated. The fabricated particles were characterized using backscattered scanning electron microscopy (BSE-SEM) and differential scanning calorimetry (DSC). Theparticle size distribution and the ratio of undercooled particles were statistically analyzed. Optimizationof the processing conditions and the successful selection of oxidants enabled undercooling of BiSn liquidmetal particles. In doing so, both micro- and nano-size particles could be fabricated with high yield (≥97%). The crystallization temperature was measured to be 0.37 Tm and the particles could preserve theirliquid state at room temperatures for months.
