PROCESS FOR PREPARING RARE EARTH BORATES AND USE OF BORATES OBTAINED IN LUMINESCENCE |
| abstract |
The invention relates to a process for the preparation of rare earth borates and the use of these borates in luminescence. The preparation process is characterized in that it comprises the following stages: boric acid and a rare earth salt are mixed, the mixture thus obtained is reacted with a carbonate or a bicarbonate; precipitate obtained. |
