二次烧成对CaO-B2O3-SiO2系微晶玻璃结构和性能的影响
Effects of second sintering on structure and properties of CaO - B2O3- SiO2 glass ceramics
摘要
Abstract
CaO-B2 O3-SiO2 (CBS) glass ceramics was prepared by dry-process. The effects of first sintering and second sintering on sintering properties and dielectric properties at 10 MHz were investigated. The relationships among second sintering, micro-structures and dielectric properties of CBS glass ceramics were studied by X-ray diffraction (XRD) and scanning electron microscope(SEM). The results indicated that compared with the first sintering, the second sintering had some effects on obtaining small size grain, increasing shrinking & the bulk density and optimizing microwave dielectric properties, No new crystalline phase was observed in the systems. The sample could be sintered at 875℃ with X/Y shrinking of 14. 33％ and the density of 2. 46 g/cm3. It had a dielectric constant of 6. 21, a dielectric loss of 3.5 × 10 -3 at 10 MHz. And the CTE value of CBS glass ceramics measured at on temperature of 875 ℃was 11.86 × 10-6/℃, the flexure strength was 157.36 MPa.关键词
