摘要

In this study, the particle size of diamond was used as a variable to investigate the properties of glass-diamond composites. A low melting point borosilicate glass was selected and its thermal analysis was performed by TG-DSC. The phase composition of the glass-diamond composites was analyzed by XRD, and SEM images showed the microstructure of the composites. Thermal properties of the composites were characterized by thermal conductivity and coefficient of thermal expansion (CTE). The bending strength was measured and the results showed that the glass-diamond composites with 30 μm diamond had the lowest CTE and the highest thermal conductivity and bending strength.
