Ceramic substrate and preparation method and application thereof
The invention discloses a ceramic substrate and a preparation method and application thereof, and relates to the technical field of ceramic substrate processing. The preparation method of the ceramic substrate comprises the following steps: taking ceramic powder with the particle size of 0.1-10 [mu] m, mixing the ceramic powder with an aqueous suspension in which a binder and a plasticizer are suspended and dispersed, preparing a tape casting slurry, and carrying out tape casting to obtain a green sheet; carrying out vulcanization pressing on the green blank sheet by adopting a 100-400-mesh grid to obtain a reticulated blank sheet with reticulated patterns printed on the surface; and sintering the reticulated blank piece at normal pressure to obtain the ceramic substrate. According to the preparation method disclosed by the invention, the ceramic powder with relatively wide particle size distribution is adopted for preparation, so that the surface roughness is improved; meanwhile, reticulate patterns are pressed through grid vulcanization, the pressure maintaining time is optimized, and after normal-pressure sintering, the surface roughness of the ceramic substrate can be effectively improved, copper and the ceramic substrate can be combined more tightly, and the peel strength of copper foil can be effectively improved.
本发明公开了一种陶瓷基板及其制备方法和应用，涉及陶瓷基板加工处理技术领域；陶瓷基板的制备方法，包括步骤：取粒径为0.1‑10μm的陶瓷粉料，与悬浮分散有粘结剂和增塑剂的水性悬浮液混合并配制成流延浆料，流延成型，得到生坯片；采用100‑400目的网格对所述生坯片进行硫化压制，得到表面印制网纹的网纹坯片；将所述网纹坯片进行常压烧结，即得所述陶瓷基板。本发明的制备方法，采用粒度分布较宽的陶瓷粉进行制备，利于提高表面粗糙度；同时网格硫化压制出网纹，并优化保压时间，常压烧结后，即可有效提高陶瓷基板的表面粗糙度，能够使铜与陶瓷基板的结合更紧密可有效提高铜箔的剥离强度。
