A large variation of these properties has been found within the wide homogeneity ra~ge of Ta~: . t.he resistivity increases with carbon deficiency fro~ 25 to. a~out 150 p{l·c~, and t~e magnetic susceptibllity changes its sign, the material being paramagnetic at stOlchiometry and dlamagnetlc at the low-~~bon phase boundary. The temperature coefficient of the resistivity has also been found to be charactenstlc for each composition and to depend strongly on the Ta: C ratio.. A method for preparation of homogeneous samples of a predetermmed carbon content has been developed. The experimental results are discussed in the light of previous theories.
