Abstract

The inter-granular-Nano porous  0.65PMN-0.35PT  ceramic abbreviated as “PMNT were  fabricated  for the first time by introducing  pore forming agent multi walled carbon nanotubes (MWCNT), the  thermal analysis of Nano tube, and the effect of MWCNT ratio on their density, phase analysis, microstructure were investigated. the complete burnout of the MWCNT   as pore forming agent was about 850℃ .The ideal sintering procedure of PMNT ceramic was arranged in agreement with thermo gravimetric reading of  Nano material.  XRD test  indicated that MWCNT as Nano  voids  shaping  factor did not influence on  PMNT ceramic crystallographic structure. The porosity of PMNT ceramic 24% more than that of pure sample while the density
