Abstract

Abstract:

The BaAl₂Si₂O₈-xwt%Li₂O-B₂O₃-SiO₂ (x=0, 0.1, 0.3, 0.5, 1.0, 2.0) ceramics with small amount of Li₂O-B₂O₃-SiO₂ (LBS) glass addition were prepared by solid state sintering. The sintering temperature, structure and microwave dielectric properties of BaAl₂Si₂O₈ (BAS) ceramics with xwt%LBS glass addition were investigated. The results show that the LBS glass can greatly reduce the sintering temperature, promote the growth of grain and the transformation of hexacelsian-to-celsian of BAS ceramics. As x=0.1, all the hexacelsian were transformed into celsian, and the second phase was not observed as x≤2.0. The 0.3wt%LBS glass can promote the density, dielectric constant and Q × f value increase, and the absolute value of τ_f decrease. Especially, the BAS ceramics with the 0.3wt%LBS glass addition sintered at 1275 ℃ shows a good Q × f of 34570 GHz, and the dielectric properties are ε_r= 6.74 and τ_f = -15.97 × 10 ^-6/℃.
