An Experimental ThermodYlllLmic ]~quation (ETE) temperature scale valid from 0.2 to 2.0 oK has been calculated for JIe 3 . The scale is based on new compariso Jl s, (P" p.), of Ile3 a nd He' vapor pressures above 0.9 oK; on the 1958 lIe' temperature scale; and on the best available data for several thermodynamic properties of Ile 3 from 0.2 to 2.0 oK.The '1'62 Full-Ran ge Working Equation (F WE) scale,In P 3=-2.49174/ 7' + 4.80386 -0.286001 7' + 0.198608 1'2 -0.0502237 1'3+ 0.00505486 T' + 2.24846 In T fits t he E T E sCRle and the (P 3, 7'58) data and is therefore valid for use from 0.2 to the critical point, 3.324 oK. The maximum de':.iation from the ETE scale is 0.4 mdeg and ~he standard deviation from the input data is 0.21) mdeg. The fit to the seven recalculated Isotherms of K eller in the range of the 1962 Ile 3 scale ean be determined by conver ting Kell er's P,sto equ ivalent P /s, using di rect P, to P3 interpolation equati.ons. The fit of the 19.62 Ile3 scale is as good as the fit of the 1958 11e' scale to the same Isotherms, the ave rage displacements of the two scales both bein g 1.5 mdeg below t he isotherms. The average standard deviations for ( ' 1 ' 62 -'1'iso) and for ( 7\ 8-1'iso) are 1.2 and 1.0 mdeg, respectively, for these seve n isotherms.

Experimental Thermal Conductivity of Helium-3

et al. 1966

The thermal conductivity of liquid He* at pressures of 0.11, 6.78, and 27.0 atm has been measured down to 0.06°K. For each pressure the conductivity passes through a minimum, the temperature of the minimum decreasing with increasing pressure. At temperatures greater than J°K the thermal conductivity is nearly independent of pressure. The effect of pressure is to decrease the conductivity. The pressure effect increases monotonically down to the lowest temperature.

Thermodynamic Diagrams of 3He from 0.2 K to 300 K Based Upon its Debye Fluid Equation of State

On the basis of the equation of state and the phase equilibrium equations of helium-3 ( 3 He), a computer program for calculating the thermodynamic properties of 3 He has been created. With this program, many iso-property tables were prepared for generating p-h and T-s diagrams of 3 He over the range of temperature from 0.2 K to 300 K and pressures up to 300 MPa. Compared with the previous diagrams plotted with interpolated experimental data sets, the new ones are more thermodynamically consistent and cover a broader temperature and pressure range. The estimated overall random errors of the diagrams are within 2 %.
