TAPE CASTING SLURRY COMPOSITION FOR PREPARATION OF SILICON NITRIDE SINTERED BODY
The present invention relates to a tape casting slurry composition for preparation of a silicon nitride sintered body. The slurry composition of the present invention exhibits a viscosity suitable for a tape casting method, and thus can easily control the area and thickness of a manufactured green sheet, and as a result, a large-area silicon nitride sintered body with a circuit board thickness can be manufactured without a post-processing process, such as polishing. In addition, according to the present invention, a silicon nitride sintered body can be manufactured using low-priced raw materials and a simplified process, thereby ensuring efficiency and economical efficiency of the manufacturing process.
La présente invention concerne une composition en suspension pour coulage en bande pour la préparation d'un corps fritté en nitrure de silicium. La composition en suspension de la présente invention présente une viscosité appropriée pour un procédé de coulage en bande, et permet ainsi de réguler facilement la surface et l'épaisseur d'une feuille verte fabriquée, et en conséquence, un corps fritté en nitrure de silicium de grande surface présentant l'épaisseur d'un circuit imprimé peut être fabriqué sans mise en œuvre d'un processus de post-traitement, tel que le polissage. De plus, selon la présente invention, un corps fritté en nitrure de silicium peut être fabriqué à l'aide de matières premières bon marché et par un procédé simplifié, garantissant ainsi l'efficacité et la rentabilité du processus de fabrication.
본 발명은 질화규소 소결체 제조를 위한 테이프 캐스팅용 슬러리 조성물에 관한 것이다. 본 발명의 슬러리 조성물은 테이프 캐스팅법에 적합한 점도를 나타내어 제조되는 그린시트의 면적 및 두께를 용이하게 조절할 수 있으며, 이에 따라 연삭 등의 후가공 공정 없이 회로 기판 두께의 대면적 질화규소 소결체를 제조할 수 있다. 또한, 본 발명에 따르면 저가의 원료 및 단순화된 공정으로 질화규소 소결체의 제조가 가능한 바, 제조 공정의 효율성 및 경제성을 확보할 수 있다.
