Thick Glassy Water by Liquid Quenching on a Diamond Wafer

By quenching water on a liquid nitrogen cooled diamond wafer, we have produced 0.7 mm thick glassy water disks about 1000 times thicker than previously produced by quenching liquid water. Our in situ measured cooling rates of 110−271 K/s are far lower than the 105−106 K/s previously thought necessar...

Summary:By quenching water on a liquid nitrogen cooled diamond wafer, we have produced 0.7 mm thick glassy water disks about 1000 times thicker than previously produced by quenching liquid water. Our in situ measured cooling rates of 110−271 K/s are far lower than the 105−106 K/s previously thought necessary for formation of a glass from liquid water. Conversely, these are also the highest measured cooling rates that we are aware of for quenching this thickness of water. The glassy disks quenched on diamond are transparent, have a density of 1.04 g cm-3, and exhibit a glass-transition temperature of 138 K and a crystallization temperature range of 150−190 K.
