synthesized and their physical properties after infrared (IR) exposure was investigated. The
zircon filler concentrations were 0, 0.5, and 1 wt%. The infrared exposures were 50 and 150
lx. The crystal and molecular structures of the unexposed and exposed samples were
investigated using x-ray diffraction (XRD) and Fourier-transform Infrared (FTIR)
spectroscopy. At the same time, the thermo-mechanical and optical properties were …
