Composite dielectric ceramic powder co-fired magnet, preparation method thereof and composite dielectric ceramic powder co-fired magnetic sheet
The invention discloses a composite dielectric ceramic powder co-fired magnet, a preparation method of the composite dielectric ceramic powder co-fired magnet and a composite dielectric ceramic powderco-fired magnetic sheet. The method comprises the following steps: 1) respectively preparing a microwave ferrite magnet and a hollow ceramic green body; and 2) sleeving the outer side of the microwave ferrite magnet with the hollow ceramic green body, and sintering to obtain the composite dielectric ceramic powder co-fired magnet. Under the condition that the dielectric constant of the microwaveferrite magnetic column is not changed, a ceramic body (such as a ceramic ring) with a high dielectric constant is introduced outside the microwave ferrite magnetic column, so that the microwave ferrite magnetic column and the ceramic body are tightly combined together through co-firing; and on the other hand, co-firing is actually equivalent to counter-firing of microwave ferrite, and the performance of the microwave ferrite magnetic column is further improved. The method can improve the dielectric constant of the microwave ferrite, reduce the loss of the ferrite, reduce the production cost and improve the efficiency.
本发明公开了一种复合介电陶瓷粉共烧磁体、其制备方法及复合介电陶瓷粉共烧磁片，所述方法包括以下步骤：1)分别制备微波铁氧体磁体和中空陶瓷生坯；2)将中空陶瓷生坯套在所述微波铁氧体磁体的外侧，烧结，得到复合介电陶瓷粉共烧磁体。能够在不改变微波铁氧体磁柱的介电常数的情况下，在其外部引入高介电常数的陶瓷体(例如陶瓷环)，共烧使二者紧密地结合在一起，另一方面，共烧实际上相当于对微波铁氧体进行了反烧，进一步提升了其性能。该方法能够提高微波铁氧体的介电常数，降低铁氧体的损耗并降低生产成本，提高效率。
