Calorimetric Properties of Some Alkali Pentaborate Hydrates From 15 to 370 °K
Measurements of the heat capacity of ammonium pentaborate tetrahydrate (NH(4)B(5)O(8)·4H(2)O), potassium pentaborate tetrahydrate (KB(5)O(8)·4H(2)O), and sodium pentaborate pentahydrate (NaB(5)O(8)·5H(2)O) were made in the range of about 15 to 370 °K and the data were used to obtain a table of smoot...

description | Measurements of the heat capacity of ammonium pentaborate tetrahydrate (NH(4)B(5)O(8)·4H(2)O), potassium pentaborate tetrahydrate (KB(5)O(8)·4H(2)O), and sodium pentaborate pentahydrate (NaB(5)O(8)·5H(2)O) were made in the range of about 15 to 370 °K and the data were used to obtain a table of smoothed values of thermodynamic functions from 0 to 370 °K. The measurements on sodium pentaborate pentahydrate were terminated at 345 °K because the temperature drifts that were observed above this temperature were considered to arise from gradual volatilization of the water of hydration. |
