About the possibility of the TG-CVI processes realizing at the decreased temperatures

The possibility of TG-CVI processes realizing at the temperatures lower than 550 ^deg C is proved. Such temperature decreasing is possible due to the use of the complicated hydrocarbons, for example, propane and butane mixture. It is experimentally set that threshold temperature of the effective carbon deposition from such mixture is 520...530 ^deg C. The properties of the achieved materials are similar to the ones of the composites produced with the use of the traditional TG-CVI methods based on the methane pyrolysis at 900...1100 ^deg C. Research results can be a base for the development of the new composites and capability enhancement of the methods of the radioactive wastes immobilizing by the pyrocarbon matrix
