- Abstract
Glass-ceramic materials of the CaO-BO-SiO (CBS) system added with various amounts of AlO have been prepared by conventional melting and heat treated crystallization method. The effects of AlO on the sintering characterization and dielectric properties have been investigated. With increasing the AlO content, the bending and stretching vibrations in [SiO] became weak. XRD patterns of samples with ≥3 wt% AlO introduce cyclowollastonite (α-CaSiO) as single crystallized phase of sintered glass-ceramics. It is found that the optimal sintering temperature for this glass ceramics is 800 °C for 30 min, and the sinterability was obviously improved by AlO additive. CBS glass ceramics sample with 5 wt% AlO achieved the best sintering characterization and dielectric properties (ε ≈ 7, tan δ = 1.9 × 10 at 1 MHz), which is proposed to be suitable for LTCC application.
