    • The shadow mask of a color cathode ray tube is arranged in the vicinity of a phosphor screen. The shadow mask is provided with through-holes that select the electron beams emitted from the electron guns. A layer comprising, as a filler, one or other of a metal, metal oxide, metal carbide, metal nutride, or a mixture of two or more of these, for example zirconium powder and, as a binder, one of an amorphous metal oxide compound, amorphous metal hydroxide compound or a mixture of these, for example silicon oxide, is formed on the surface of the shadow mask. This layer increases thermal radiation of the shadow mask, reduces electron scattering, and raises the residual emissivity.
    • 彩色阴极射线管的荫罩布置在荧光屏附近。 荫罩设置有选择从电子枪发射的电子束的通孔。 包含作为填料的金属,金属氧化物,金属碳化物,金属金刚石或其中的两种或更多种的混合物作为填料的层,例如锆粉末和作为粘合剂的无定形金属氧化物之一 化合物,无定形金属氢氧化物化合物或其混合物,例如氧化硅,形成在荫罩的表面上。 该层增加了荫罩的热辐射,减少了电子散射,并提高了剩余发射率。
