【Abstract】 The SiO 2 thick films is deposited on silicon substrate by Flame Hydrolysis Deposition (FHD). The thickness of the films is up to 40 μm , and the deposition speed is as high as 8 μm per minute. Then, the films is consolidated in electric furnaces both in vacuum and gasoline situation, and several kinds of states of silica are obtained, including of uniform and transparent silica glass. Finally, the silica films is analyzed by meanings of XRD, microscope, etc.更多还原
