U+6C18 "氘" CJK Unified Ideograph-# is a Chinese character that represents the chemical element deuterium, a stable isotope of hydrogen whose nucleus contains one proton and one neutron. This character is composed of the radical for gas or vapor, 气, which appears on the left side, and the phonetic component 刀 on the right, which contributes to its pronunciation "dāo" in Mandarin. In scientific contexts, it is used to refer to heavy hydrogen, commonly denoted by the symbol D or ²H, and is significant in nuclear chemistry, isotopic labeling, and the production of heavy water for certain types of nuclear reactors.
