Abstract

Spray pyrosysis is a process to prepare particles and films by evaporating and decomposing droplets of precursor solutions in the order of 1-10 micrometer in diameter. Key elements of the spray pyrolysis process include precursor, solvent, droplet generator, and reactor. Various combination of these 4 elements produces wide range of particles and films. In general. the current status of the spray pyrolysis technology is not quite promising for commercial success. However, this process will be feasible to produce multicomponent functional materials of controlled morphology. In this paper, current status of the spray pyrolysis technology is introduced with the emphasis of production of fluorescence particles.

분무 열분해법이란 전구체를 용해시킨 용액을 수 마이크론에서 수십 마이크론 크기의 액적으로 분무한 후, 용매를 증발시키고 석출된 전구체를 열분해하여, 입자 및 필름을 제조하는 공정이다. 이 분무 열분해법의 핵심 요소는 전구체,용매, 액적 제조 그리고 분해 반응기 등 4가지이다. 이 4가지 요소의 적절한 조합에 의해서 현존하는 거의 대부분의 입자와 필름을 제조할 수 있는 범용성이 높은 기술이다. 현재 기술 수준으로는 상업적인 성공을 거두기는 힘들지만 향후 다성분계의 입자나 필름, 혹은 고기능성 입자의 제조에 응용될 경우 매우 유용한 기술로 각광을 받을 전망이다. 본 총설에서는 이 분문 열분해법을 이용해서 만들어지는 입자 중에서 주로 형광체를 중심으로 지금까지 개발된 다양한 분무 열분해 공정 기술을 소개한다
