CHEMICAL COMPOUND FORMING METHOD USING ISOSTATIC-PRESSURE SOLID-STATE REACTION
The present invention provides a method for forming a chemical compound by which contamination by the outside can be minimized while productivity for batches can be excellently maintained. According to the method for forming a chemical compound according to the present invention, a chemical compound is synthesized through a solid-state reaction by isostatic-pressurizing a solid-state material mixture. According to the present invention, a desired chemical compound, in particular, a thermoelectric material can be synthesized by isostatic-pressurizing an inert gas of a positive pressure and minimizing introduction of oxygen and contaminants from the outside. Further, the present invention is advantageous in an aspect of productivity due to a large-scale (not less than several kg/batch) because a vacuum quartz tube is not used.
배치당 생산성이 우수하면서도 외부로부터의 오염을 최소화할 수 있는 화합물 형성 방법을 제공한다. 본 발명에 따른 화합물 형성 방법에서는 고상 원료 혼합물을 등방 가압하며 가열하여 고상반응을 통해 화합물을 합성한다. 본 발명에 따르면, 양압의 불활성 가스가 등방 가압을 하여 외부로부터 산소, 오염물질 등의 유입을 최소화하여 원하는 화합물, 특히 열전재료를 합성할 수 있다. 또한 진공 석영관을 사용하지 않기 때문에 배치에 제한이 거의 없어 대규모(수 kg/batch 이상) 상합성을 할 수 있어 생산성 측면에서 뛰어나다.
