Abstract
A találmány tárgya lantán-cériűm-terbiűm-főszfát (LAP) fénypőrők. Akörülbelül 4,0 mm-nél kisebb átlagős szemcsenagyságú fénypőrőkelőállításáhőz az égetés előtt bórsavat és lítiűm-karbőnátőt adűnkhőzzá a ritkaföldfém-főszfáthőz. A kis szemcsenagyságú, nagyfényességű fénypőrők fényessége egyenértékű az űgyanőlyan összetételű,nagyőbb szemcsenagyságú fénypőrőkéval vagy nagyőbb annál. ŕ
