Abstract
The formation of graphite crystals was found at relatively low temperatures as 900-1100°C from the powder mixtures of poly (vinyl alcohol) and either iron or nickel oxide. From the mixtures with Fe2O3, graphite crystals were formed above 900°C, but those with NiO the heat treatment at 1000°C for more than 5h. Before graphite formation from the mixtures with NiO, well-developed turbostratic structure was found to be formed. Formation of graphite crystals at the temperatures as low as 900-1000°C was supposed to occur through the dissolution and precipitation from nickel melt, but through the decomposition of various iron carbides.
