Abstract

PURPOSE: To improve dispersibility and coating property by coating boric acid compound on the surface.
CONSTITUTION: Water soluble boric acid salt (for instance, compounds, such as sodium tetraborate Na2B4O7.10H2O, potassium tetraborate) are added in the fluorescent material suspension and are agitated. Then, water soluble metal salt compounds such as zinc sulfate, and aluminum sulfate are also added and the boric acid compound which is produced by the above reaction is coated on the surface of the fluorescent material. A product is obtained through each process of filtration→ washing with pure water→drying→and screening.
