| titleOfInvention | PROCESS FOR PREPARING YELLOW-POTASSIUM POTASSIUM POTATOES FOR ILLUMINATED DEVICES |
| abstract | The invention relates to a process for the preparation of photoluminescent pigments used for lighting devices. The process according to the invention consists in that, in a first step, the wet precursor Y-Gd-Al-Ce is prepared by precipitation at a temperature of 60-90 ° C while adding yttrium-gadolinium- aluminum-cerium and urea in a ratio of 1: 4 to a dilute urea solution at a pH of 8.0 ... 8.2, followed by the maturation, centrifugation and separation of the precursor Y-Gd-Al-Ce, which it is dried and in the second step thermal synthesis takes place at a temperature of 1200 ... 1600 ° C, in nitrogen, with ammonium chloride or alkaline or alkaline-earth flora, as a mineralizer, resulting in a homogeneous granulometric powder , polycrystalline, yellow-orange color. |
