Abstract

To prepare zinc oxide powder, three types of sodium-based alkali precipitants such as NaOH, Na2CO3, NaOH/NaHCO3 were compared to the differences in the manufacturing process of zinc oxide powder from zinc precipitate products like intermediates with the consideration of thermodynamic reaction. The prepared zinc precipitate products by the reaction with the sodium-based alkali precipitant were confirmed to respectively hydroxy zinc chloride (Zn5(OH)8Cl2·H2O) and zinc carbonate hydroxide (Zn5(OH)6(CO3)2·H2O) from XRD analysis. Zinc oxide particles were compared in heat treatment at 800℃ according to sodium-based alkali precipitants. The mixed NaOH and NaHCO3 of alkali precipitant reaction was contributed to synthesize the more uniform zinc oxide particles.

산화아연 분말을 제조하기 위해 3종류의 나트륨계 알칼리 침전제인 수산화나트륨, 탄산나트륨, 수산화나트륨/탄산수소나트륨을 이용하여 반응에 따른 열역학적 고찰과 아연 침전생성물로부터 산화아연 분말 제조 공정의 차이점을 비교하였다. 나트륨계 알칼리 침전제와의 반응으로 생성된 아연 침전생성물은 각각 히드록시염화아연(Zn5(OH)8Cl2·H2O)과 탄산아연수산화물 (Zn5(OH)6(CO3)2·H2O)임을 XRD를 통해 확인하였다. 나트륨계 알칼리 침전제에 따라 800℃에서 열처리하여 생성된 산화아연 입자 크기를 비교하였다. 혼합된 수산화나트륨 및 탄산수소나트륨의 알칼리 침전제 반응으로 보다 균일한 산화아연 입자를 제조할 수 있었다.
