초록
수평회전식 수열법에 의해 운모 분말을 합성하였다. 수열조건은 출발원료로 K2O, Al(OH)3 그리고 SiO2의 비는 1 : 3 : 3mol%로 하고 수열용매로 8 mol%의 KOH를 함께 추가하여 260 oC에서 72시간 동안 반응시켰다. 합성한 분말은 수직형 수열처리법에 의한 은나노 코팅 운모 제조를 위해 사용하였다. 은나노 코팅의 처리를 위한 수열조건은 출발원료로 합성한 분말로 하고, 수열용매로 0.5 l의 3차 증류수, 그리고 1,000 ppm의 은나노 졸을 코팅원료로 사용하여 160~260oC 범위에 서 72시간 동안 반응시켰다. 처리 후 결정구조, 은나노 코팅 여부 및 코팅된 운모의 특성은 XRD, SEM, TEM-EDX 및 shake plask법을 통해 분석하였다.
Abstract
Mica (muscovite) powders were synthesized by hydrothermal method (horizontal turning method). The hydrothermalconditions for the synthesis of mica were prepared by the ratio of K2O : Al(OH)3:SiO2 = 1 : 3 : 3 mol% as the starting materialswith KOH (8 mol%) solution as the hydrothermal solvent and reaction temperature at 260oC for 72 hrs. The synthetic powderas nano silver coating were prepared by the synthetic powder as raw materials, triple distilled water (0.5l) solution as thehydrothermal solvent with nano silver sol (1,000 ppm) as the material of nano silver coating and reaction temperature at160~260oC for 72 hrs. After hydrothermal treatment, structural, judgment of nano silver coating and character of nano silvercoated mica were examined by XRD, SEM, TEM-EDX and shake plask method.Key words Muscovite, Horizontal turning method, Nano silver coated mica, Hydrothermal method
