Density and Surface Area Measurement

  • Akshoy Kumar Chakraborty


Harmon and Parmelee (1942) noted that the specific gravity of kaolinite drops abruptly at about 450 ℃ when the mineral is dehydrated and a poorly ordered structure develops. The specific gravity gradually increases as the kaolinite is heated to higher temperatures, probably indicating some development of order at 950–1,000 ℃ there is an abrupt increase in specific gravity to a value higher than that of original. The sudden increase in specific gravity can be correlated with the high-temperature crystalline phase developing at this temperature interval.
