Instrumentation:

In Figure is display a block diagram of a differential thermal analyzer. It consists of subsequent basic components:

1.         Furnace Assembly

2.         Sample and reference holder along with temperature detector

3.         Temperature programmer

4.         Amplifier and recorder

5.         Atmosphere control equipment for furnace and sample holder

An instrument measures the differential temperature of the sample as a function of temperature or time while the temperature increases at a constant linear rate.

Source of Uniform heating:

Nichrome (chromium alloy and nickel) furnace could be used up to 1300 °C, platinum and its alloys up to  1750 °C and molybdenum (Mo) for higher range up to 2000 °C. Special categories of higher frequency induction heating might be used for higher temperatures.
