Novel method for preparation of silver-tin oxide electrical contacts

روش جدیدی برای تولید کنتاکت‌های الکتریکی نقره-اکسید قلع

ABSTRACT

 Introduction : MOST of  the  electrical  contact materials  in  use  today  contain cadmium oxide particles that are volatile and toxic. Because of the  fact  that  vaporization of cadmium  oxide  during  switching could be detrimental  to workers' health,  its use in contact mate- rials  has  been  banned  by  health  organizations  in  some  other  countries. To replace the cadmium oxide, many foreign compa-  nies have utilized tin oxide in silver electrical contacts.
