WebFeb 29, 2012 · Determination of crystallite size Table 2 shows that the values of ( m1 / β1) exp were obtained from a plotted graph in Fig. 2. The values are 0.77, 0.67 and 0.69 for samples S1, S7 and S8, respectively. Subsequently, the respective crystallite sizes are 17.68, 26.12 and 38.93 nm (see Table 2 ). WebCrystallite size is the size of a single crystal domain inside the particles or grains. A grain can be composed of several crystals. The size of the diffracting crystallites is often important in describing the reactivity of a ceramic material, because surface area increases with decreasing particle size (see Chapter 5.1 ).
