Mo and MoO3-x nanoparticles were fabricated in HRTEM on a room temperature table by electron beam irradiating MoO3. Micro - MoO 3 may be turned into MoO3-x when irradiating intensity is more than 1021 e/cm2 s. With irradiating time prolonged , Mo nanoparticles were formed from MoO3-x. The phenomenon may be interpreted by electron beam activation and "knock - down" effect. Oxygen atoms in MoO3 microparticles were separated by means of absorbing electron beam energy. At the meantime, the microparticles were broken into nanoparticles by electron beam "hammer".
