본문내용
1.Objective
-Learn to the thermal analysis methods of Thermal Gravimetric Analysis(TGA) and Differential Thermal Analysis(DTA). learn to the analyze the thermal properties of the material.
2.Theoretical Backgrounds
① Thermal Gravimetric Analysis (TGA)
thermal gravimetric analysis (TGA) is a type of testing performed on samples that determines changes in weight in relation to change in temperature. Such analysis relies on a high degree of precision in three measurements: weight, temperature, and temperature change.

2. Chemical
① Both TG and DTA curve at 225℃ is falling. DTA curve represents the descent of the endothermic reaction. TG curve, while the fall, DTA curve an endothermic reaction to the dehydration, decomposition, reduction is a phenomenon.
② Both TG and DTA curve at 317℃ is falling. 1 and can be seen that the same phenomenon. Thus, dehydration, decomposition, reduction reactions cause.
