pulverization of high temperature materials

Materials An Open Access Journal of Materials Science TiO 2 materials with high crystallinity between 67% and 81% and surface area up to 134 m 2 /g have been obtained both by SG and HT methods In general the surface area and pore volume of the TiO 2 -HT samples are larger than those of TiO 2 -SG ones -pulverization of high temperature materials-,Processing-structure-property relationships in solid-state Inspired by the concept of mechanochemistry 29 -31 high shear and compressive forces from the rotating kneading disks in SSSP are applied to the polymeric material in the solid state well below the melting T sub m or glass transition T sub g temperatures …… Get More
