Phase relation of some sulfide system-(4) : especially Cu-Fe-s system

Phase relation studies for termary Cu-Fe-S system have been performed by author and some students. Their results are described as mainly phase diagrams. Some diagrams are already reported, but adds additional new data and new knowledge. Phase relations from 900 to 500℃ were performed by evacuated silca glass tube method, and from 500 to 300℃ were studied by thermal gradient transformation method under hydrothermal condition. Phase relations at 900, 800, 700, 600 and 500 by dry method were obtained and their phase diagrams are given in the Figs. 5, 6, 7, 8 and 9 and at 500, 400, 300℃ determined by hydrothermal sinthesis under 29 MPa(300kg/㎠), 98 MPa(1,000kg/㎠) and 196 MPa(2,000kg/㎠) are also givin in Figs. 10, 11, 12, 13, 14, 15 and 16.
