Barium-cobalt-zinc-niobium-based microwave dielectric ceramic and preparation method thereof
The invention provides a preparation method of barium-cobalt-zinc-niobium-based microwave dielectric ceramic, which comprises the following steps: before tabletting barium-cobalt-zinc-niobium-based microwave dielectric ceramic powder, adding barium-zinc-niobium-based microwave dielectric ceramic powder and/or barium-cobalt-niobium-based microwave dielectric ceramic powder into the barium-cobalt-zinc-niobium-based microwave dielectric ceramic powder, so that the resonant frequency temperature coefficient of the barium-cobalt-zinc-niobium-based microwave dielectric ceramic powder is adjusted toa preset interval range. In the preparation method of barium-cobalt-zinc-niobium-based microwave dielectric ceramic, before tabletting, a step that barium-zinc-niobium-based microwave dielectric ceramic powder and/or barium-cobalt-niobium-based microwave dielectric ceramic powder are/is added into the barium-cobalt-zinc-niobium-based microwave dielectric ceramic powder to adjust the temperature coefficient of resonance frequency of the barium-cobalt-zinc-niobium-based microwave dielectric ceramic powder is added. Therefore, the method avoids batch scrap caused by large difference and disqualification of resonant frequency temperature coefficients of different batches of barium-cobalt-zinc-niobium-based microwave dielectric ceramic powder.
本发明提供了一种钡钴锌铌基微波介质陶瓷的制备方法，包括：在将钡钴锌铌基微波介质陶瓷粉料进行压片之前，向钡钴锌铌基微波介质陶瓷粉料中添加钡锌铌基微波介质陶瓷粉料和/或钡钴铌基微波介质陶瓷粉料，以使钡钴锌铌基微波介质陶瓷粉料的谐振频率温度系数调整至预设的区间范围。本发明的钡钴锌铌基微波介质陶瓷的制备方法，由于在压片之前，还包括有向钡钴锌铌基微波介质陶瓷粉料中添加钡锌铌基微波介质陶瓷粉料和/或钡钴铌基微波介质陶瓷粉料来调整钡钴锌铌基微波介质陶瓷粉料的谐振频率温度系数的步骤，避免了因不同批次钡钴锌铌基微波介质陶瓷粉料的谐振频率温度系数可能相差较大，不合格而导致的批量报废。
