Heavy water (deuterium oxide, ²H₂O, D₂O) is a form of water that contains a larger than normal amount of the hydrogen isotope deuterium (²H or D, also known as heavy hydrogen), rather than the common hydrogen-1 isotope (¹H or H, also called protium) that makes up most of the hydrogen in normal water. The presence of deuterium gives the water different nuclear properties, and the increase of mass gives it slightly different physical and chemical properties when compared to normal water. It can be used to create ice and snow at higher temperatures since its melting point is 3.82 C.
