Preparation method of water-based tape casting ceramic, slurry and ceramic
The invention discloses a water-based tape casting ceramic preparation method, slurry and ceramic, and relates to the technical field of ceramic preparation, the preparation method comprises the following steps: mixing powder, a dispersant, water and a solution containing borate radicals to obtain first slurry; the powder comprises ceramic powder and glass powder; adding a pH regulator into the first slurry, and regulating the pH value of the first slurry to a preset pH value; the first slurry is stirred, a binder is dropwise added into the first slurry in the form of liquid drops, second slurry is obtained, and the binder is polyvinyl alcohol; leveling by taking the second slurry as slurry for tape casting, and drying to obtain a tape casting film belt; the cast film belt is subjected to pressing treatment, and a biscuit is obtained; and sintering the biscuit to obtain the ceramic matrix. The prepared film belt is high in toughness and easy to press, after the film belt is subjected to hot pressing, the film belt is not cracked after being sintered, and the prepared ceramic is high in quality.
一种水基流延陶瓷制备方法、浆料以及陶瓷，涉及陶瓷制备技术领域，制备方法包括：将粉体、分散剂、水以及含硼酸根的溶液进行混合，得到第一浆料；粉体包括陶瓷粉以及玻璃粉；向第一浆料添加PH调节剂，将第一浆料的酸碱度调节至预设酸碱度；搅拌第一浆料并以液滴的形式向第一浆料滴加粘结剂，得到第二浆料，粘结剂为聚乙烯醇；将第二浆料作为用于流延的浆料进行流平，干燥后得到流延膜带；将流延膜带进行压合处理，得到素坯；将素坯进行烧结处理，得到陶瓷基体。本申请制备得到的膜带韧性强、容易压合，膜带热压合后，烧结不会开裂，制得的陶瓷质量高。
