Preparation method of high-activity Ti/2B nano-powder

The invention relates to a preparation method of high-activity Ti/2B nano-powder, and belongs to the technical field of energetic nano-materials. By adoption of the preparation method of the high-activity Ti/2B nano-powder, the problems that a conventional nano-material preparation method is high in cost, low in yield, complex in process and high in material activity loss rate are solved. According to the preparation method, micro-sized boron powder is synthesized through a reduction method; in a dry (argon protection) environment, micro-sized titanium powder and the boron powder are placed ina stainless steel ball-milling tank in a certain proportion so as to be milled by a high-energy nano impact-milling machine through a low-temperature mechanical ball-milling method (dry and wet), sothat the high-activity Ti/2B nano-powder is obtained; and the high-activity Ti/2B nano-powder can be applied to the fields of explosives and powders, payloads, ceramic materials and the like. The nano-powder prepared through t
