[‚dif·ə′ren·chəl ′thər·məl ə′nal·ə·səs]
(thermodynamics)
A method of determining the temperature at which thermal reactions occur in a material undergoing continuous heating to elevated temperatures; also involves a determination of the nature and intensity of such reactions.

The thermal properties of oxy-aluminum-treated wood were assessed using thermogravimetric analysis and differential thermal analysis. The literature indicates that untreated wood begins to thermally degrade at approximately 250[degrees]C, but decomposition of its principal structural constituent, cellulose, does not commence until a temperatue of 300[degrees]C is reached (LeVan 1984, Rowell and LeVan-Green 2005).
Differential scanning calorimetry (DSC) and differential thermal analysis (DTA), which both calculate heat emission or absorption, make up the largest market segment, accounting for approximately half of all thermal instruments sold.
