The density of liquid iron sulfide (FeS) was measured up to 3.8 GPa and 1800 K using an X-ray absorption method. compression curve FeS fitted the Vinet equation state. isothermal bulk modulus its temperature pressure derivatives were determined a nonlinear least-squares fit. parameter sets were: K0T = 2.5 ± 0.3 at T 1500 K, (dK0/dT)P -0.0036 0.0003 GPa/K, (dK0/dP)T 24 2. These results suggest that is more compressible than Fe-rich Fe-S.
