In this article we will discuss about:- 1. Apparatus of Differential Thermal Analysis 2. Types of Thermal Peak Reactions 3. Applications. Apparatus of Differential Thermal Analysis: The DTA apparatus consist of the following: 1. Sample holder, usually ceramic, nickel, or platinum. 2. Furnace with a temperature controller to provide a constant rate of heating. 3. Thermocouples for the measurement of [...]
In this article we will discuss about:- 1. Principle of Transmission Electron Microscopy 2. Components of Transmission Electron Microscopy 3. Applications. Principle of Transmission Electron Microscopy: The transmission electron microscope can be compared with a slide projector. In a slide projector, light from a light source is made into a parallel beam by the condenser lens; this passes through the [...]
In this article we will discuss about:- 1. Principle of X-Ray Diffraction 2. Equipment of X-Ray Diffraction 3. Analysis 4. Methods 5. Advantages. Principle of X-Ray Diffraction: When a monochromatic X-ray beam with wavelength A is projected onto a crystalline material at an angle , diffraction is reinforced only along specific directions, as shown in Fig. 3.19 defined by Bragg's [...]
