METHOD OF PRODUCING LANTHANUM-GALLIUM SILICATE CRYSTALLINE ELEMENTS OF Y-CUT Russian patent published in 2011 - IPC B24B1/00 C09K3/14 

Abstract RU 2430824 C2

FIELD: process engineering.

SUBSTANCE: invention relates to processing of crystalline elements from lanthanum-gallium silicate (LGS) and may be used in radio electronic engineering for fabrication of HF resonators and broadband filters. Proposed method comprises stepwise grinding of LGS plates by emery with "ЭБ8", M28, M14 grain size, chemical etching of plates in solution HCl:HF:H2O=1:10:30 at 70-90°C, mechanical finishing with removal of surface layer to depth of 5 mcm, chemical etching in solution HCl:HF:H2O=1:50:150 and finish machining of plates.

EFFECT: higher efficiency of processing.
