Abstract
Inventia de fata se refera la un procedeu de obtinere a sulfurii de zinc de puritate avansata. Procedeul, conform inventiei, consta în aceea ca reactia de precipitare dintre sulfatul de zinc "p.l." si tiosulfatul de sodiu "p.l." are loc la cald, se separa prin cernere umeda o parte din sulful rezultat în proces si produsul de reactie se filtreaza si se usuca, apoi se calcineaza la 700...900 degree C când se obtin sorturi de sulfura de zinc "p.l." cu distributii granulometrice diferite si grad de alb ridicat care pot fi utilizate la prepararea luminoforilor.The present invention relates to a process for obtaining zinc sulfide of advanced purity. The process according to the invention consists in that the precipitation reaction between zinc sulphate "p.l." and sodium thiosulphate "p.l." takes place by heat, some of the resulting sulfur is separated by wet scraping and the reaction product is filtered and dried, then calcined at 700 ... 900 ° C when zinc sulfide sorts are obtained "p.l." with different granulometric distributions and a high degree of whiteness that can be used in the preparation of luminophores.
