세라믹 분말의 제조방법{MANUFACTURING METHOD OF CERAMIC POWDER}TECHNICAL FIELD [0001] The present invention relates to a method for producing a ceramic powder,

본 발명은 세라믹 분말의 제조방법에 관한 것으로, 보다 상세하게는 결정도가 향상되고, 균일한 입자 크기 및 분포를 가지는 세라믹 분말의 제조방법에 관한 것이다.The present invention relates to a method for producing a ceramic powder, and more particularly, to a method for producing a ceramic powder having an improved crystallinity and a uniform particle size and distribution.

세라믹 분말은 그 사용처에 따라 차이가 존재하지만 일반적으로 입자의 크기 및 형상 제어가 용이하여야 하며, 입도 분포가 균일한 특성이 요구된다.
Ceramic powder differs depending on its use, but it is generally required to control the size and shape of particles and to have uniform particle size distribution.

일반적으로 세라믹 분말을 제조하는 방법인 고상법은 세라믹 원료를 건식으로 혼합하여 소성 및 제품화하는 방법으로서, 원료의 혼합 및 제조 공정이 단순하여 낮은 제조 단가가 적용 가능하다는 장점이 있는 반면, 입자 크기 및 입도 분포 제어가 어려운 단점을 가진다.
Generally, the solid phase method, which is a method of producing ceramic powder, is a method of dry mixing and calcining ceramic raw materials and has a merit that a low manufacturing cost can be applied because raw materials are mixed and manufactured. It is difficult to control the particle size distribution.

세라믹 분말을 제조하는 다른 방법인 액상법 및 기상법 등의 제조방법은 고상법 대비 상대적으로 구형 입자 및 입자의 크기를 제어하는데 유리하지만 장치의 구성이 복잡하다는 문제가 있다.
Other methods of producing ceramic powder, such as liquid phase method and vapor phase method, are advantageous in controlling the size of spherical particles and particles relatively to the solid phase method, but there is a problem that the structure of the apparatus is complicated.
