Nanothermite, as the name suggests, is thermite in which the particles are so small that they are measured in nanometers is an ultra-fine-grained (UFG) variant of thermite that can be formulated to be explosive by adding gas-releasing substances.
Nanothermite was costly to produce and dangerous to use and thus their application was limited to laboratory uses or high-value clandestine operations
