Preparation method of microwave and millimeter wave ferrite substrate
The invention discloses a preparation method of a microwave and millimeter wave ferrite substrate, which comprises the following steps of: firstly, adding a solvent, a dispersing agent, an adhesive and a plasticizer into ferrite powder, and mixing to obtain casting slurry; carrying out tape casting and cutting to obtain a to-be-fired sample; and finally, firing the to-be-fired sample in a holding mechanism to obtain a finished product. The holding mechanism comprises a sample bearing table with a firing through hole and a sample pressing table, and the the to-be-fired sample is clamped between the sample bearing table and the sample pressing table. The method has the advantages that the thickness of the ferrite substrate is continuously adjustable, deep grinding, cutting and other machining in a traditional dry pressing method are not needed, and the production efficiency is improved; and the finished product has the advantages of smooth surface, compact micro-structure, few pores, high density, good performance and high yield.
本发明公开了一种微波毫米波铁氧体基片的制备方法，首先将铁氧体粉料中加入溶剂、分散剂、粘接剂和增塑剂进行混浆，得到流延料浆；再流延成型，裁切得到待烧样片，最后将待烧样片置于保持机构烧制即得成品；保持机构包括具有烧制通孔的样片承台和样片压台，二者将待烧样片夹在中间。采用本发明的显著是，铁氧体基片厚度连续可调，不需要传统干压法的深磨、切削等加工，提高生产效率；成品表面平整，微观结构致密、气孔少、密度高，性能好，良品率高。
