摘要： A hot cathode in a wire form that is useful in a vacuum tube, a CRT or a fluorescent display tube is disclosed. The cathode (4a) is composed of a heat-resistant metal (3) in a wire form that holds on it an electron-emitting metal material that is made of 0.2 - 20 wt% of a rare earth metal oxide in admixture with an alkaline earth metal oxide the balance of which contains at least barium oxide. The reduction of oxide barium to barium as a result of reaction with the cathode wire is so much retarded that an increased emission current will be produced from the cathode not only in its initial operation but also through out its operation.
