Perlite can expand 7–16 times over its original volume if heated between 760 °C and 1100 °C , and it is thermal and acoustical insulator. The low density and light weight characteristics of expanded perlite (ExP) makes it one of the best retainer materials suitable for preparing form-stable composite PCMs (F-SCPCMs) for TES purposes , .
Expanded perlite was used as a porous aggregate with a particle size of 2.38–4.78 mm, and provided by Zanjan Perlite Co. Iran. The specific heat capacity of expanded perlite was 837 J kg −1 K −1 and the thermal conductivity was about 0.05 W m −1 K −1 in 24 °C. The chemical composition of the expanded perlite is shown in Table 1.
Finally, concrete samples were thermally evaluated by a simple apparatus and also the leakage-prevention performance was investigated. Expanded perlite was used as a porous aggregate with a particle size of 2.38–4.78 mm, and provided by Zanjan Perlite Co. Iran.
By this coating process, paraffin leakage reduced the to zero in expanded perlite particles (4–6 mm) with a proportion of (P:EP, 52.5:47.5% mass). In another study, Li et al. [ 21] used two kinds of material, namely silane and nanosilica as coating materials to control the paraffin leakage in two different sizes of perlite.
Among these, perlite is an amorphous volcanic glass possessing high porosity and very low density. It also shows high thermal stability and it is relatively cheaper , . Perlite can expand 7–16 times over its original volume if heated between 760 °C and 1100 °C , and it is thermal and acoustical insulator.
In order to obtain this kind of energy storage composite PCMs, several paraffins have been encapsulated in form-stable mass fractions into different porous matrices such as diatomite, expanded perlite, and vermiculite as host matrix , , , , , .
