6-Feb-2023: Scientists at UCL created a new type of ice

Scientists at University College London (UCL) have recently created a new type of ice that matches the density and structure of water. The ice is called medium-density amorphous ice.

Properties:

• Matches density and structure of water
• Created by shaking regular ice in a container with steel balls at a temperature of -200°C
• Appeared as white granular powder that stuck to the metal balls.

Ice is less dense than liquid form due to their unusual property. Water can solidify in many regular arrangements depending on conditions such as pressure and the speed of freezing. Amorphous ice, however, is different as it has no such order. Hence, this study could probably help in studying water’s mysterious properties.
