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
