Abstract
An examination of the thermal characteristics of moist Ca(OH) 2 showed three peaks at 100, 400-450 and 250-300 degrees C. The effect at 250-300 degrees C was caused by calcium aluminate hydrate formed from the reaction of Ca(OH)2 with the aluminum sample holder. This effect could be eliminated by using a sample holder made of gold.
