摘要

CRYSTALS PBO-B2O3-Ag2O having a relationship PREFERRED weights in the range 76-88: 10-15: 2-10 HAS TRANSITION TEMPERATURES LESS THAN CRYSTAL 300 CY are used especially JOINING TOGETHER FOR CERAMIC SUBSTRATES SUCH AS TO LINK INTEGRATED CIRCUITS A ceramic layers. CRYSTALS may be formulated with AG PARTICLES AND ORGANIC PASTA AND PERFORMING AS PROVIDING ADHESIVOS CONDUCTIIOS.
