Equations of State for Mg(OH)₂ Brucite

Equations of State for volume, and for a³ and c³:

	K0	K'0	(¶ KT/¶ T)P	a 0	a 1
	(Gpa)		(Gpa/K)	(10-5/K)	(10-8/K2)
Room temperature Birch-Murnaghan EoS:
volume	39.6(14)	6.7(7)	-	-	-
a- axis	79.1(23)	3.7(8	-	-	-
c- axis	18.24(76)	6.27(40)	-	-	-
High temperature Birch-Murnaghan EoS:
volume	38.7(15)	7.0(8)	-0.015(4)	7.3(3)	3.6(13)
a- axis	80.5(13)	3.4(4)	0.001(3)	3.2(2)	-0.8(9)
c- axis	16.9(13)	6.4(7)	-0.008(1)	18.2(3)	-2.7(20)

High temperature results use the room-temperature 3rd-order Birch-Murnaghan equation of state

in which the room temperature parameters K₀ and K'₀ are replaced by their high-temperature counterparts:

K_T and K'_T and V₀ is replaced by V_T.

We call this the high-temperature Birch-Murnaghan equation of state.

Because the compressibility of the a- and c-axes are very different, equivalent terms K_a and K_c, etc. were calculated:
