Raman spectra of the PbTiO3 films via sol-gel process were investigated by using a Jobin Yvon U1000 system. Compared with the Raman spectra of the PbTiO3 single crystals, Raman peaks of PbTiOs films shift downward, which is attributed to the stress effect in the PbTiO3 films exerted by the substrate...

The influence of mechanical activation on the leaching behaviour of scheelite was studied by means of fine grinding in an attritor and subsequently HCl leaching in presence of PO_4~(3-). Results showed that after fine grinding in the attritor,the reaction rate of scheelite with HCl-Na_3PO_4 solution...

Two-dimension consolidation under the cylindrical converging shock wave has been studied. The major parameters influenced on the explosive consolidation quality are the specific energy,detonation pressure and specific impulse.It seems to be favourable to improving con- solidation quality by a lower ...
