| Abstract: | The present paper discussed the volatility and the diffusion of lead in (Ba,Pb)TiO3 PTC materials during calcination and sintering processes. The technical process with a fast heating and cooling rate during high temperature sintering was adopted to refrain effectively the volatliy of lead and to improve the PTC characteristics. The excellent PTC properties in (Ba,Pb)TiO3 materials was obtained and the sintering mechanism as well as its its influence was discussed. |
