MICROBEADS MADE FROM YTTRIUM-ALUMINOSILICATE GLASS FOR RADIOTHERAPY AND METHOD OF PRODUCING SAID BEADS Russian patent published in 2012 - IPC C03C12/00 C03C3/83 C03C3/95

Abstract RU 2454377 C1

FIELD: chemistry.

SUBSTANCE: present invention relates to medicine, particularly 5-100 mcm microbeads for radiotherapy, which are made from aluminosilicate glass having high content of Y₂O₃. The microbeads made from yttrium-aluminosilicate glass for radiotherapy with diameter from 5 to 100 mcm contain Y₂O₃, Al₂O₃ and SiO₂, with the following ratio of components, mol %: Y₂O₃ - 17-22; Al₂O₃ - 19-25; SiO₂ - 53-64.

EFFECT: obtaining articles which do not contain glass crystallisation products and foreign inclusions.
