About the Fusion black filled icon
This icon diagrams a nuclear fusion reaction: a two-particle nucleus and a three-particle nucleus travel along arrows into a spiky starburst at the center, where a cluster of circles fuses, while two outgoing arrows release a single particle and a four-particle nucleus. It suits physics and chemistry teaching material, clean energy and reactor explainers, science museum signage, research lab sites, and slides about breakthroughs or merging ideas.
Filled arrows and heavy strokes give the burst real impact, and the differing particle counts on each side make the reaction readable as a process, not just decoration. It pairs with atom, reactor and energy icons for a science set. The diagram carries detail, so use it at 48px or larger or in hero and slide art.
This is the solid black filled version of the fusion icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
