<p>Disclosed are dry-powdered, double-coated R or G phosphor particles (P) with silica (C1) and titanic-coupling (C2) for use in manufacturing a CRT screen assembly, a method of manufacturing them and a CRT comprising a screen assembly manufactured by using them. Silica below 0.5 weight % and titanic-coupling below 2 weight % are dispersed and coated on the surface of the R or G phosphor particles, which have improved chargeability and flow characteristics. The CRT comprises a screen assembly manufactured by using the silica-and-titanic-coupling coated R or G phosphor particles, thus said screen comprises picture elements of red or green color emitting phosphors with silicon below 0.5 weight % and titanium below 2 weight % dispersed and coated thereon.</p> |
