Experiments were designed to investigate the influence of controlling sintering mechanism on electrical properties of multilayer PTCR chip. During the preparation process, heating rate, sintering temperature, high-tem...
The constitution and firing-technology of Ni paste were experimentally investigated. The experimental resalts show that the contact resistance could be lowered by adding glass powder and Boron powder, respectively use...
Raman and IR spectra of Nb-doped PTC Ba1-xPbxTiO3 semiconducting ceramics (x = 0,0. 28,0. 296,0. 313,0. 330,0. 370) have been measured, and mode assignments of Raman scattering frequencies and infrared absorption peak...
