Large-size ceramic substrate and preparation method thereof
The invention relates to the technical field of ceramic substrates, in particular to a large-size ceramic substrate and a preparation method thereof. The preparation method at least comprises the following steps: (1) powder ball milling: a solid phase component is subjected to wet ball milling, ball millstones comprise 15mm large balls, 10mm medium balls and 5mm small balls, the mass ratio of the large balls to the medium balls to the small balls is 1: 2: 1, the dosage of the ball millstones is 3 times of the mass of the solid phase component, and the ball milling time is 24 hours; (2) preparing slurry; (3) tape casting: coating the slurry to obtain a blank strip, and drying the blank strip in a drying chamber with the temperatures of a first temperature zone, a second temperature zone and a third temperature zone of the drying chamber being 30 DEG C, 70 DEG C and 105-110 DEG C respectively; (4) stamping; and (5) sintering. By adjusting the ball-milling stone ratio of the powder and adjusting the tape casting drying temperature, defects can be avoided, the surface roughness of the product is reduced, and the strength of the product is improved.
本发明涉及陶瓷基板技术领域，具体涉及一种大尺寸陶瓷基板及其制备方法。制备方法至少包括如下步骤：（1）粉体球磨：采用湿法球磨固相组分，球磨石包括15mm大球、10mm中球和5mm小球，大球、中球和小球的质量比为1：2：1，球磨石用量为固相组分质量的3倍，球磨时间为24h；（2）浆料配制；（3）流延成型：涂布浆料得到坯带，将坯带置于干燥室内干燥，干燥室一温区、二温区、三温区温度分别为30℃、70℃、105‑110℃；（4）冲模；（5）烧结。本发明通过调整粉体的球磨石配比、调整流延成型干燥的温度，能避免缺陷的产生，降低了产品的表面粗糙度，提升了产品的强度。
