METODO PARA FABRICAR UN TUBO DE RAYOS CATODICOS.

摘要

A suspension comprising electrically conductive material, a binder, and from 3% to 30% by weight of sodium carbonate or potassium carbonate is applied to a wall portion of a cathode-ray tube and then dried and fired. This provides a layer in which hardly any bubbles have formed during the firing of the cathode-ray tube and which during firing produces no gases which detrimentally influence the emission of the cathode.
