摘要: We present a local microstructure study of liquid and amorphous alumina by means molecular dynamic method. The simulation was performed on systems prepared at five different densities temperatures from 400 to 800 K for glass 3000 liquid. has been analyzed through the pair radial distribution function, bond-angle characteristics voids void aggregations. focused two kinds aggregations: clusters tubes. results showed that many clustered nearby created very large cavity with volume times bigger than aluminum atom. In addition, we found tube in low-density systems, which consisted 75% all spread over entire system. diffusion mechanism high-density also discussed presented here.
