摘要： The red and blue color cathode ray tube phosphors for color television are pigmented with a coating of an aqueous-insoluble silicate-based glass matrix containing pigment particles. When incorporated into a tridot color cathode ray tube, the contrast of the tube is improved. The coated particles are formed by dispersing the particles in a slurry with a silicate, the pigment particles and an optional wetting agent, and evaporating the slurry to dryness. The dried coated particles are then heated in order to insolubilize the glass matrix, and soluble ions are then removed by washing.

摘要： A pigmented silicate coated phosphor is disclosed and a process for producing the phosphor. The process involves preparing a relatively uniform aqueous mixture of particles of a phosphor, particles of a deagglomerated pigment, and a free flowing agent and then adding a precipitating agent to the mixture in an amount sufficient to cause the free flowing agent and pigment to co-precipitate upon and coat the phosphor, followed by separating the pigmented phosphor from the resulting liquor. A relatively uniform mixture is formed of the resulting dried phosphor, a water soluble silicate, and water the water being in an amount of sufficient to allow the silicate to coat the surface of the phosphor particles. The mixture is heated at a sufficient temperature for a sufficient time with sufficient agitation to produce the final non-agglomerated silicate coated pigmented phosphor.
