背景技术
众所周知,半导体等电子元器件的发展,材料和工艺是基础,微波介质陶瓷(MWDC)材料,是指应用于微波频段电路中作为介质材料并完成一种或多种功能的功能陶瓷材料,以其优异的微波介电性能在微波电路***中发挥着介质隔离、介质传导以及介质谐振等重要功能。在现代通讯中被广泛用于谐振器、滤波器、双工器、介质基板等微波元器件的生产中。例如,介质谐振器、介质滤波器、介质双工(多工)器、卫星授时天线等均是现代通信的重要元器件。基于优异的微波电性能,微波介质陶瓷元器件被广泛应用于移动通信、卫星通讯、卫星导航与定位、航空航天、汽车电子、物联网等领域。
随着第五代无线通信,即5G的发展,以及即将到来的6G发展时代,对现代通讯技术中的关键基础材料——微波介质陶瓷材料的要求越来越高,在要求品质因数Q尽可能高、频率温度系数τf尽可能小的同时,也要求介电常数εr向着更高和超低两个方向发展,以满足不同频段的通信要求。
εr=5.8左右的超低介电常数的微波介质材料在国际上还未面世或应用。本发明是在这种背景下开发成功的,以满足6~9GHz及以上更高频段的通信要求。
发明内容

现代通信用超低介电常数微波介质材料的制备方法,包括如下步骤:
步骤a、根据上述组分配方,准确称量各种原料并倒入树脂球磨罐内,加入去离子水和ZrO2磨球,二者比重为:原料/去离子水=1/3;
步骤b、然后将树脂球磨罐放到行星球磨机上球磨,以300r/min转速连续球磨6小时,出料后将浆料放入烘箱中,在80~120℃下烘干;
步骤c、烘干后的物料在1000~1250℃下预烧2小时,再将煅烧后的料粉倒入树脂球磨罐中,加入去离子水,二者比重为料粉:水=1:2,进行二次球磨,以300r/min转速连续球磨6小时,出料后烘干;
步骤d、将烘干后的物料粉碎后过60目筛,得到粒度均匀的粉体;
步骤e、在粉体中加入14~17%粉体质量的浓度为10wt%的聚乙烯醇粘合剂,进行造粒,在研钵中研磨均匀后,取60目~120目粒度的料粉,在130Mpa左右压力下干压成型;
步骤f、成型后在450-500℃保温2小时进行充分排胶,然后以3℃/min的升温速率,在1150~1300℃下烧结4小时,最终制得介电常数在5-6.5左右的新型超低微波介质材料。
与现有技术相比,本发明的有益效果是:
本发明通过调整主要组分和微量添加剂的比例,改善微波介质材料的电性能,在本发明的制备工艺条件下,可以得到εr接近6、τf≈±10ppm/℃、品质因数符合要求的超低微波介质材料,为更高频率微波器件的开发提供一个全新的材料基础,满足6~9GHz及以上更高频段的通信要求。

步骤a、根据上述组分配方,准确称量各种原料并倒入树脂球磨罐内,加入去离子水和ZrO2磨球,二者比重为:原料/去离子水=1/3;
步骤b、然后将树脂球磨罐放到行星球磨机上球磨,以300r/min转速连续球磨6小时,出料后将浆料放入烘箱中,在80~120℃下烘干;
步骤c、烘干后的物料在1000~1250℃下预烧2小时,再将煅烧后的料粉倒入树脂球磨罐中,加入去离子水,二者比重为料粉:水=1:2,进行二次球磨,以300r/min转速连续球磨6小时,出料后烘干;
步骤d、将烘干后的物料粉碎后过60目筛,得到粒度均匀的粉体;
步骤e、在粉体中加入14~17%粉体质量的浓度为10wt%的聚乙烯醇粘合剂,进行造粒,在研钵中研磨均匀后,取60目~120目粒度的料粉,在130Mpa左右压力下干压成型;
步骤f、成型后在450-500℃保温2小时进行充分排胶,然后以3℃/min的升温速率,在1150~1300℃下烧结4小时,最终制得介电常数在5-6.5左右的新型超低微波介质材料。
