Abstract:
The present invention relates to a method for manufacturing a SrTiO3 series varistor using grain boundary segregation, and more particularly, to a method for manufacturing a SrTiO3 series varistor by sintering a powdered composition in which acceptors such as Al and Fe are added in powdered form and then sintered under a reducing atmosphere and heat-treated them in the air to selectively form electrical conduction barriers at grain boundaries in a process for manufacturing SrTiO3 series varistor having an excellent non-linear coefficient and a breakdown voltage suitable for use.
