| Abstract: | A PTC soldering iron capable of autometically keeping constant tempcrature has been prepared with (Ba1-xPbx)TiO3 systems of semiconducting ceramic as the heating element. The curie temperature of the ceramic used is of 320-350 and the PTCR effect of the ceramic is of 3.5-4.5 orders of magnitude. The power consumption of the soldering iron is 8 - 20W. The soldering iron can be operated for a wide range of voltage ratings either AC or DC. It is characterized by fast heating-up, automatic compensation of high heat losses, low idling temperature and long working life. |
