Low-temperature sintered 95Al2O3 microwave dielectric ceramic with high dielectric property
The invention discloses a low-temperature sintered 95Al2O3 microwave dielectric ceramic with a high dielectric property and a preparation method of the low-temperature sintered 95Al2O3 microwave dielectric ceramic. The preparation method is characterized in that 95.0 wt% of high-purity Al2O3 powder is taken as a main raw material, 5.0 wt% of a sintering aid formed by mixing a proper amount of Nb2O5, CuO and ZrO2 is added, the mixture is uniformly mixed and molded, the molded mixture is put into a muffle furnace and sintered at 950-1025 DEG C for 2-5 h, and the 95Al2O3 microwave dielectric ceramic with high density and high dielectric property (the relative density is greater than or equal to 98%, the dielectric constant is 9.6-9.9, and the Q * f value is 13000GHz-16000GHz) can be obtained. The 95Al2O3 microwave dielectric material with high density and high dielectric property can be obtained at a low temperature, the process is simple, operation is convenient, cost reduction and large-scale production are facilitated, and meanwhile, the method has important significance on energy consumption reduction, environmental protection and sustainable development.
本发明公开了一种低温烧结高介电性能95Al2O3微波介质陶瓷及其制造方法。其特点是以95.0wt%高纯Al2O3粉体为主要原料加上5.0wt%由适量Nb2O5、CuO、ZrO2混合而成的烧结助剂，混合均匀并成型后，放入马弗炉中，在950~1025℃下烧结2‑5h，即可得到高致密度、高介电性能的95Al2O3微波介质陶瓷（相对密度≥98%，介电常数：9.6~9.9，Q×f值：13000GHz~16000GHz）。本发明可以在较低温度下获得高致密度、高介电性能的95Al2O3微波介质材料，且工艺简单、操作方便，有利于降低成本和大规模生产，同时对减少能源消耗、保护环境可持续发展有着重要的意义。
