A nuclear bomb refers to a weapon that uses the huge energy released by an explosive nuclear reaction to kill and destroy targets. Explosive nuclear reaction is a nuclear reaction that uses self-sustaining and rapid nuclear fission or fusion reaction to instantly release huge energy to produce a nuclear reaction explosion and form a huge destructive effect. The destructive power of nuclear bomb is very great, and it is now considered as a powerful manifestation of national strength and a hidden deterrent. According to the structural principle, it can be divided into atomic bomb, hydrogen bomb, hydrogen uranium bomb and nuclear weapon with special properties. (such as neutron bombs, nuclear heterogeneous weapons, antimatter weapons);

1, the main raw material of the atomic bomb: uranium 235 is the main charge of the atomic bomb.

2. Main raw materials of hydrogen bombs: hydrogen bombs can be charged with deuterium and tritium or lithium deuterium -6.

3. The main raw materials of uranium hydrogen bombs: apart from using deuterium, tritium and lithium 6 as the main nuclear fuel, hydrogen bombs also contain a small amount of plutonium 239 or uranium 235 (plutonium 239 is mostly used now), because they need atomic bombs as "detonators" to detonate.

4. The main raw materials of neutron bomb: lithium deuterium 6 and lithium tritium 6. Remove the uranium 238 shell of the hydrogen bomb and add a beryllium reflector.
