Physical and Chemical Characteristics of Urea Ammonium Nitrate Solutions
The solutions contain a remarkably low amount of water and nevertheless have a low salt-out temperature:
Grade, %N: | 28 | 30 | 32 |
---|---|---|---|
Ammonium nitrate (%): | 40 | 42 | 45 |
Urea (%): | 30 | 33 | 35 |
Water (%): | 30 | 25 | 20 |
Specific gravity at 16 °C: | 1.283 | 1.303 | 1.320 |
Salt-out temperature (°C): | -18 | -10 | -2 |

Famous quotes containing the words physical, chemical and/or solutions:
“It takes a good deal of physical courage to ride a horse. This, however, I have. I get it at about forty cents a flask, and take it as required.”
—Stephen Leacock (18691944)
“If Thought is capable of being classed with Electricity, or Will with chemical affinity, as a mode of motion, it seems necessary to fall at once under the second law of thermodynamics as one of the energies which most easily degrades itself, and, if not carefully guarded, returns bodily to the cheaper form called Heat. Of all possible theories, this is likely to prove the most fatal to Professors of History.”
—Henry Brooks Adams (18381918)
“Football strategy does not originate in a scrimmage: it is useless to expect solutions in a political compaign.”
—Walter Lippmann (18891974)
