Antoine coefficients magnesium
Antoine coefficients magnesium
(OP)
I am trying to generate a curve for the vapour pressure of liquid magnesium metal as a function of temperature. If anyone has a reference I would be very greatful. Alternatively if anyone knows the Antoine coefficients for pure magnesium that would help me out.
Thanks in advance,
Thanks in advance,

RE: Antoine coefficients magnesium
From Metallurgical Thermochemistry, 5th Edn., p. 366 (1979), with T in oK:
log pMg(s), Torr = -7780/T – 0.855 log T + 11.41 [298K to mp]
log pMg(liq), Torr = -7550/T – 1.41 log T + 12.79 [mp to bp, 1378 K]
A more recent work, ASM Metals Reference, 3rd Edn., p. 158 (1993) gives tabular data from which you can derive an equation:
P, atm T, oC
0.0001 516 (solid)
0.001 608 “
0.01 725 (liquid)
0.1 886 “
0.50 1030 “
1.0 1107 “
Hope this helps,
