Method for forming a silica film on a face panel of a cathode ray tube

摘要

A method for forming a silica film on a face panel is disclosed. The method includes steps of preparing a first composite having a staring material of a silica-titania two component system where alcohol is added as a catalyst; preparing a second composite having a titaniumalkoxide or a derivative of the titaniumalkoxide as a catalyst; mixing the first and second composites at a predetermined ratio; agitating the face panel; and calcinating the coated colloidal solution at a temperature of 160-200 DEG C. The silica-titania two-component system is selected from a group consisting of a tetraethyl-silicate and a tetraethyl-silicate oligomer. The tetraethyl-silicate oligomer has a degree of polymerization of 40, 51 or 56.
