Figure 9
Arrhenius analysis of CSP of KDP for applied uniaxial pressure of 125 MPa, based on data for total pore volume fraction at 313 K (40°C), 323 K (50°C) and 333 K (60°C). The activation energy is for loss of porosity per mole of solid KDP filling the pore space during densification. Vertical bars are estimated standard uncertainties for modeled total porosities (left-hand plot) and computed standard uncertainties of the straight-line fit (right-hand plot). Also see Allen et al. (2022). |
