Description

technical field

[0001] The invention belongs to the field of physical or chemical methods, and in particular relates to a method for synthesizing oxide powder by detonation at high temperature and high pressure. Background technique

[0002] Nanopowder is on the order of nanometers (10 -9 m) ultrafine particles, the size of which ranges from 1 to 100 nm. Due to the extremely small particles, the number of atoms on the grain boundary is more than that inside the grain, with a high concentration of grain boundaries, and a large number of atoms in the defect center of the grain. Therefore, nanopowders have effects such as small size, surface and interface, quantum size, and macroscopic quantum tunneling. Compared with large-particle micropowders with the same composition, nanomaterials often exhibit many unique properties that cannot be compared with other structural materials, such as superstructure. Plasticity, low elasticity, low density, high strength, large magnetic resi...
