Abstract
Influence of Ca/Si on the crystallization, microstructure and dielectric properties of CaO-B 2O 3-SiO 2 glass was studied by using XRD, DSC and SEM. The results indicate that when m(Ca/Si ratio)<1.08, calcium borosilicate glass sintering temperature higher than 900°C, but it is m>1.08, CBS department of the sintering temperature of glass is far lower at 900°C. When m reaches 1.767, CBS can not be sintered; with the increase of CaO content, Ca 2SiO 4 crystals gradually increased, leading to the gradual reduction of wollastonite phase, resulting in gradual increase in quartz; the samples were C2, C5, C7 dielectric loss sintered <2×10 -3 at 1 MHz.
