CaCO3/Si2O ' nH2O NANOCOMPOSITE PARTICLES, Si2O ' nH2O NANOMATERIAL AND METHOD OF PRODUCING THE SAME

摘要

A composite CaCO3/SiO2.nH2O nanoparticle is prepared from nano-class CaCo3 particle as templete through uniformly coating a nano-thickness layer of SiO2.nH2O on its surface. It can replace the white carbon black to be used as the reinforcing material of rubber. A nano-class hollow material or hollow mesaporous material can be prepared from said nanoparticles through calcining and dissolving in acid. Its advantages are high specific surface area and high pore diameter uniformity. It has wide usage field.
