摘要
本文的目的是讨论BaO -TiO2 -Sm2 O3 系微波陶瓷的研究过程。该陶瓷用不同工艺来制作 ,并用XRD分析其物相组成 ,从而获得了介电常数为 78、频率温度系数为 - 4 .3× 10 -6/℃、Q(2GHz)≥ 30 0 0的微波陶瓷。结果表明 ,该陶瓷满足了 6 0 0MHz到 180
The purpose of the paper is to discuss the developing process of the microwave ceramics of series BaO-TiO 2-Sm 2O 3.Different technolongy method was used to make this microwave ceramics analysised crystal crystal phase contents through XRD.Therefore,the properties of the microwave ceramics,which have 78 dielectric constant -4.3×10 -6 /℃ temperature coefficient of frequency,Q(2GHz)≥3000,have been acquired.The result shows that the microwave ceramics meet the requirement of microwave device used of 600MHz to 1800MHz.
