About the Name

Ice Formation-Tetragonal Crystal

(Represented in the ARCTIC Logo)

Crystallized water, or ice, has a greater variety of crystalline structures than perhaps any other material. Ordinary ice (like you might skate on) has a hexagonal structure; water at different temperatures and pressures forms solids that are rhombohedral, tetragonal, cubic, or orthorhombic in structure. Some forms of “frozen” water are disordered (non-crystalline)
