Abstract

This paper focuses on both thermal and mechanical properties of the composite pastes. Heat-treatment was carried out at temperatures up to 105 and 900 °C for 6h, respectively. Thermal conductivity of the specimens enriched with 3 wt% nano-SiO2 was approximately 60% higher than that of pure paste. Volume heat capacity of the composite pastes displayed 28% increase. Moreover, the composite pastes contributed to ~25% improvement of compressive strength. XRD, and TG-DSC were employed to investigate the cause of physical and thermal changes in the heated specimens.
