Abstract: The advancement of propulsion technologies for space exploration has led to the consideration of novel materials, such as nuclear-grade boron nitride (BN) and boron carbide (B4C) powders, as potential fuel and shielding materials. These compounds exhibit high-temperature stability, neutron absorption capabilities, and superior mechanical properties. This review explores the properties of BN and B4C in the context of nuclear thermal propulsion (NTP) and nuclear electric propulsion (NEP), analyzing their effectiveness in enhancing thrust efficiency, fuel longevity, and radiation shielding. Special emphasis is given to the optimal ratio of BN to B4C in nuclear fuel applications based on recent experimental and computational studies, along with a detailed examination of their mechanical properties. The Boron Carbide is also used for the manufacturing of Atom Bomb and Nuclear Bomb. India has made a strive forward in Nuclear technology by the manufacturing of nuclear capable Brahmos Missile using Boron Nitride powder technology.
