Hollow Multiphase Ceramic Microspheres of Al+Cr2O3+SiO2 System Prepared by Self-Reaction Quenching Technology
This paper aims to study preparation and mechanism of hollow ceramic microspheres.With Al+Cr2O3+SiO2+sucrose+epoxy resin as reactive system,Al2O3-based hollow ceramic microspheres are synthesized and reaction mechanism of hollow ceramic microspheres is established.Results show that the quenching products consist of hollow spherical or irregularly spherical particles and irregularly powders.Spherical or irregularly spherical particles are hollow structure and constitutive of Al2O3-SiC diphase and a few Cr3Si,Cr7C3.The preparation of hollow ceramic microspheres includes igniting by heating,forming ceramic thawy droplets and fast cooling.The great deal of air produced by burning epoxy resin and sucrose is the key reason why hollow ceramic microspheres are formed.
