Spherical Sb/Sb{sub 2}O{sub 3} composite nanoparticles {approx}80 nm in diameter were synthesized by innovated hybrid induction and laser heating (HILH). Under the irradiation of 80 kV electronic beams for 3 min, the aligned nanoparticles were welded into the Y-type nanorods, indicating their instability. Moreover, after annealed at {>=}400 deg. C for 1 h in air, the Sb/Sb{sub 2}O{sub 3} nanoparticles exhibit thermal instability. Their shape varies from the spherical nanoparticles, through the regular polygon nanoparticles, irregular polygon microparticles into the spear-like microparticles, as the annealing temperature increases from 400 to 600 deg. C. Beyond 500 deg. C, the Sb content inside them completely disappears. The metallic Sb inside the Sb/Sb{sub 2}O{sub 3} nanoparticles is responsible for their instability.
