| 摘要 |
Cathode structures for cathode ray tubes are produced by dispensing slurry drops of cathode material onto metallic supporting substrates, and drying the drops to form cathode layers. The slurry comprises the particles in an organic binder solution, and additionally contains particles of urea. The cathode layers are subjected to further thermal processing during their incorporation into a cathode ray tube, and are characterized by a high degree of adherence to their underlying substrates.
