Microstructural Study 3.3. Microstructural Study Figure 4 depicts the steatite powder morphology before and after milling. The steatite Figure 4 depicts the steatite powder morphology before and after milling. The steatite powder before milling exhibited rod-, plate-, or flake-shaped particles with varying sizes, as powder before milling exhibited rod-, plate-, or flake-shaped particles with varying sizes, shown in Figure 4a. Given the different shapes and sizes of the particle, Figure 4c shows the as shown in Figure 4a. Given the different shapes and sizes of the particle, Figure 4c shows nonuniform dispersion of the steatite particles in the PCM composite. The steatite powders the nonuniform dispersion of the steatite particles in the PCM composite. The steatite were then ball milled for 18 h. During milling, the ball stress on steatite particles increases, powders were then ball milled for 18 h. During milling, the ball stress on steatite particles and the particles cannot withstand their structure. As a result of the milling, the particles increases, and the particles cannot withstand their structure. As a result of the milling, the are deformed into small and fine particles, as shown in Figure 4b. The effective stirring particles are deformed into small and fine particles, as shown in Figure 4b. The effective and smaller size of the milled steatite particles cause uniform dispersion, and they exhibit good physical interaction with the paraffin wax without agglomeration in the composite, Figure 4d. Moreover, no alteration occurred in the layers of the paraffin, and instead, the nanoparticles were diffused inside the matrix. A good dispersion of the milled steatite in the paraffin wax facilitated a good connecting network and resulted in an enhancement of the heat transfer [25]. 3.4. DSC Analysis A differential scanning calorimeter (DSC 6000, PerkinElmer, Inc., Waltham, MA, USA) was used to examine the thermal characteristics of the PW, PCMS, and PCMSB. During melting, a PCM composite sample was heated continuously from 30 ◦C to 80 ◦C at a rate of 5 ◦C/min and then cooled back to 30 ◦C. Figure 5 shows the heating and cooling behavior curves of the paraffin wax and PCM/Steatite composites.PDF Image | Heat Charging–Discharging Periods of Paraffin Wax
