  Antimony  \An"ti*mo*ny\  (?;  112),  n.  [LL.  antimonium,  of  unknown 
  origin.]  (Chem.) 
  An  elementary  substance,  resembling  a  metal  in  its  appearance 
  and  physical  properties,  but  in  its  chemical  relations 
  belonging  to  the  class  of  nonmetallic  substances.  Atomic 
  weight,  120.  Symbol,  Sb 
 
  Note:  It  is  of  tin-white  color,  brittle,  laminated  or 
  crystalline,  fusible,  and  vaporizable  at  a  rather  low 
  temperature.  It  is  used  in  some  metallic  alloys,  as 
  type  metal  and  bell  metal,  and  also  for  medical 
  preparations,  which  are  in  general  emetics  or 
  cathartics.  By  ancient  writers,  and  some  moderns,  the 
  term  is  applied  to  native  gray  ore  of  antimony,  or 
  stibnite  (the  stibium  of  the  Romans,  and  the  sti`mmi  of 
  the  Greeks,  a  sulphide  of  antimony,  from  which  most  of 
  the  antimony  of  commerce  is  obtained.  Cervantite, 
  senarmontite  and  valentinite  are  native  oxides  of 
  antimony.
