Heating of perlite at high temperature (more than 800 °C) resulted into an expended perlite which is an inert, non-toxic, light in weight and acquire high surface area (1.22 m 2 g −1) [2], [3]. The structural identification of perlite revealed that its surface consists of silanol groups in which each Si atom attached with two or three –OH ...

Thermal energy storage (TES) technology is an effective means to accelerate energy efficiency and save energy, which bridged the time gap between demand and supply of energy [3], [4]. Phase change materials (PCMs) could absorb or release thermal energy through a phase change within a specific temperature range [5].

PERLITE . Domestic perlite mining generally takes place in remote areas, and its environmental impact is not severe. The mineral fines, overburden, and reject ore produced during ore mining and processing are used to reclaim the mined-out areas, and, therefore, little waste remains. Airborne dust is captured by baghouses, and virtually no runoff
