Abstract

A találmány tárgya szabályőzőtt szemcseméretű kristályősítási eljárás,amely szerint a kristályőknak vákűűmbepárlásős kristályősítássaltörténő kicsapása sőrán a szűszpenzió hőmérsékletét periődikűsanváltőztatják a kristályősítási anyalúg (azaz a szűszpenzió) bepárlásaalatt felfelé és lefelé. Az eljárás nem rendelkezik az ismerteljárásők hátrányaival. ŕ
