LOW-TEMPERATURE PHASES OF INTERFACIAL WATER IN CLAY-WATER SYSTEMS

LOW-TEMPERATURE DIFFERENTIAL THERMAL ANALYSES OF SELECTED CLAY-WATER SYSTEMS WERE MADE TO LOCATE IMPORTANT PHASE CHANGE TEMPERATURES AND TO DEFINE FRUITFUL TEMPERATURE- PRESSURE FIELDS FOR PRECISE CALORIMETRIC INVESTIGATION. IN ADDITION TO AN EXOTHERM CORRESPONDING TO INITIAL FREEZING, ONE, TWO OR THREE EXOTHERMS WERE OBSERVED BETWEEN -35 DEGREE C AND -60 DEGREES C. THE LOW TEMPERATURE EXOTHERMS DO NOT DEPEND CRITICALLY UPON WATER CONTENT, BUT CLEARLY THEY ARE RELATED TO CLAY MINERAL AND EXCHANGEABLE CATION TYPE. THE EVOLUTION OF HEAT IN THIS TEMPERATURE RANGE PROBABLY CORRESPONDS TO A PHASE CHANGE IN THE INTERFACIAL WATER. /AUTHOR/
