Effect of Heating Rate on the One‐Pot Synthesis of ZrB 2 –ZrC–SiC Ceramics by PDC Route

ABSTRACT Zirconoborosiloxane (ZBS), a preceramic oligomer, was synthesized by a nonaqueous sol–gel route in our earlier work, which yields ceramics of m‐ZrO 2 , ZrSiO 4 , and t‐ZrO 2 upon pyrolysis at 1500°C and 1650°C in argon. In the present study, a single system comprised of...

Performance evaluation of solar flat plate collectors integrated with phase change materials for thermal storage

Solar flat-plate collectors (FPCs) have many applications in low-temperature thermal systems, but they are limited due to the intermittent nature of solar radiation, the small thermal storage capacity and the poor thermal conductivity of traditional phase change materials (PCMs)....
