Abstract:
Adopting self-reaction quenching technology based on flame spraying technique, self-propagating high-temperature synthesis and quick chilling technique, hollow multiphase ceramic microspheres are prepared. With Al+Cr 2 O 3 +Fe+Fe 2 O 3 +MnO 2 as reactive system, agglomerate powders are obtained and then distinguished as thick powders and fine powders according to the different particle size. The relationship between agglomerate powders initial particle size and hollow ceramic microspheres is analyzed by the means of SEM, EDS, XRD and particle-size analyzer. The result shows that average particle diameter of thick powder is 24.49μm and that of fine powder is 17.15μm. Particle diameters of thick powder quenching product distribute within the range of 20~50μm, and those of fine powder distribute within the range of 5~30μm. The thick powder quenching product phase composition consists of Mn 2 AlO 4 ,Fe 2 O 3 ,Fe 3 O 4 ,FeCr 2 O 4 ,Cr 2 O 3 ,Al 2 O 3 The fine powder quenching product phase composition consists of Mn 2 AlO 4 ,Fe 2 O 3 ,FeCr 2 O 4 ,Fe 3 O 4.
