Title (EN) METHOD FOR PREPARING LAYERED CERAMICS
(FR) PROCÉDÉ DE PRÉPARATION DE CÉRAMIQUES EN COUCHES
(ZH) 一种层状陶瓷的制备方法
Abstract:
(EN) Provided is a method for preparing layered ceramics, comprising: formulating slurries from a ceramic powder, resin, dispersing agent and surfactant, the corresponding slurries for two adjacent layers being different in composition; placing the respective slurries into a stereolithography apparatus and curing the respective slurries by a stereolithography apparatus method to form a blank having a structure of n layers; and subjecting the blank to a drying step, degreasing step and sintering step to prepare the layered ceramics. The preparation method can produce layered ceramics having a thickness in the order of micrometers.
(FR) L'invention concerne un procédé de préparation de céramiques en couches comprenant les étapes consistant à : formuler des suspensions avec une poudre céramique, une résine, un agent de dispersion et un tensioactif, les suspensions correspondantes de deux couches adjacentes étant différentes en termes de composition ; placer les suspensions respectives dans un appareil de stéréolithographie, et durcir chacune des suspensions par un procédé utilisant l'appareil de stéréolithographie pour former une ébauche ayant une structure à n couches ; soumettre l'ébauche à une étape de séchage, une étape de dégraissage et une étape de frittage pour obtenir les céramiques en couches. Le procédé de préparation peut produire des céramiques en couches ayant une épaisseur de l'ordre du micromètre.
(ZH) 一种层状陶瓷的制备方法,包括:由陶瓷粉体、树脂、分散剂和表面活性剂制成浆料,相邻两层结构对应的浆料的成分不同;将浆料置于光固化面成型设备中,通过光固化面成型法使浆料逐层固化,形成具有n层结构的坯体;坯体经过干燥步骤、脱脂步骤和烧结步骤,制得层状陶瓷。该制备方法可以制造出微米级厚度的层状陶瓷。
