Fusion reactants

Fusion reactants refer to the substances that undergo nuclear fusion, a process where two light atomic nuclei combine to form a heavier nucleus, releasing a significant amount of energy. In stars, like our Sun, hydrogen isotopes such as deuterium and tritium fuse to create helium, accompanied by energy output that powers the star. In experimental fusion reactions on Earth, scientists aim to replicate this process using isotopes of hydrogen for clean energy. Achieving fusion could provide a nearly limitless energy source with minimal environmental impact, but it requires extreme temperatures and pressure to overcome the repulsive forces between the nuclei.
