| Abstract: | Common donor dopants are Y 3+ and Nb 5+ Usually donor doped content lies in range from o 2 to 0 3 percent Factors influencing on the content are purity of used raw materials, flux for sintering, donor doping process and the others. Effects of physicochemical properties of common donor dopants on performances of PTC thermistors are reseached and technical criteria of the donor dopants are given. |
