In order to clarify the correlation between the structure and peak position in quenched carbonaceous composite (QCC), which shows an absorbance peak similar to the 217.5nm feature seen in the interstellar extinction curve, structural changes induced by heating were studied in situ using high resolution electron microscopy. As-prepared QCC particles composed of onion-like spherules changed into a structure with well ordered (002) fringes following heating in vacuum. In addition, formation of microdiamond of about 1 nm in diameter took place by heating at 100℃. The metamorphism is discussed based on a specific configuration of sp^3 hybridization existing on the surface of QCC particles.
