When the mask is bombarded with a high energy electron beam, it will heat-up the mask and cause thermal expansion. This thermal expansion (doming effect) will occur spot displacement and deteriorate the color purity of CRT. The infrared emissivity and the electron-backscattering coefficient of the mask are two influential factors on doming behavior. The influence of mask with Bi203 and Barium coatings on the emissivity and backscattering coefficient are studied. The doming behavior is modeled directly as a function of Bi203 and Barium coatings on mask and indirectly as a function of the emissivity and the backscattering coefficient.
