Water in the liquid state at temperatures below 0°C is referred to as supercooled water. Spontaneous freezing of supercooled water occurs below –39°C. Hence, freezing catalysts are clearly essential for many natural freezing processes. A wide range of substances are able to catalyze ice nucleation. Various inorganic crystalline solids (the most well known of which ... What is the purpose of this discussion forum?
