摘　　要：In the product of carbon made from tar oil by plasma pyrogenation, some nanowires, whose diameter is 9～20 nm and whose length is 300 nm were found. The result of X ray Energy Dispersed Spectrum (EDS) indicated that it is a new compound K 2Ti 8O 15 , which has never been reported before. Compared with the corresponding stoichiometry compound K 2Ti 8O 15 , it is a non stoichiometry compound in which two oxygen atoms are absent. It is due to the fact that the intensive deoxidization occured in the experimental process and the valence of titalium is alterable. Its microstructure in detail by high revolution electromicroscopy (HREM) and X ray diffraction were studied.In the product of carbon made from tar oil by plasma pyrogenation, some nanowires, whose diameter is 9 similar to 20 nm and whose length is 300 nm were found.
