dc.description.abstract | 재생 세륨 전구체로부터 수산화세륨($Ce(OH)_3$), 염화세륨($CeCl_3{\cdot}nH_2O$), 탄산세륨($Ce_2(CO_3)_3{\cdot}8H_2O$) 및 산화세륨($CeO_2$)을 합성하고 Ultra-sonication을 통해 나노입자의 산화세륨(IV)을 제조하였다. 폐 유리연마재로부터 정제한 약 99 wt% 재생 세륨 분말을 출발물질로 하여 황산침출과 황산나트륨의 첨가조건을 통해서 황산나트륨세륨 화합물($CeNa(SO_4)_2$)을 합성하였다. 또한 황산나트륨세륨 화합물과 수산화나트륨 수용액 첨가량 비의 조건을 달리하여 수산화세륨을 제조하였으며 염산의 첨가량에 따라 염화세륨을 합성하였다. 연속적인 합성공정으로 침상형의 탄산세륨을 합성한 후 하소와 분산을 통해서 평균 30~40 nm의 산화세륨(IV)을 합성하였다.Cerium compounds such as Cerium hydroxide ($Ce(OH)_3$), Cerium chloride ($CeCl_3{\cdot}nH_2O$), Cerium carbonate hydrate ($Ce_2(CO_3)_3{\cdot}8H_2O$), Cerium oxide ($CeO_2$) were synthesized using recycled Ce precursor. Cerium(IV) oxide of nanoparticles were obtained by Ultra-sonication. Cerium-sodium- sulfate compound was synthesized through acid-leaching and addition of sodium sulfate from 99 wt% purity of Ce precursor as a starting material that was recycled from the waste polishing slurry. Moreover Cerium hydroxide was obtained from Cerium-sodium-sulfate compound by adding to sodium hydroxide solution. Then Cerium chloride was synthesized by adding of hydrochloric acid to Cerium hydroxide. Needle-shaped Cerium carbonate hydrate was synthesized in the continuous process and Cerium(IV) oxide with 30~40 nm size was subsequently obtained by the calcinations and dispersion. | en_US |
