Phase equilibrium data, obtained by the quenching technique, are presented for the liquidus temperature region of the system iron oxide‐Cr 2 O 3 ‐SiO 2 in air, which represents an O 2 isobaric section (p o2 = 0.21 atm.) through the quaternary system Fe‐Cr‐Si‐O at a total pressure of 1 atm. The diagram is dominated by a large area of coexistence of two immiscible liquids, and high liquids temperatures prevail throughout most of the system. Possible applications to refractory problems are indicated.
