Phosphor manufacturing process

Image Number 2 for United States Patent #4479521.

In the manufacture of an alkaline earth halophosphate phosphor, a tray is filled from an automatic loader with a predetermined weight of powder comprising a blend of raw ingredients for forming said phosphor. The filled tray is then vibrated with a pattern inserted therein to settle the powder into a powder mass having a shape that promotes uniformity of reaction when the powder is fired at a temperature that causes the raw ingredients to react and form said phosphor.
