Abstract

Analisis Sistem Kristal dan Unsur serta Topografi Permukaan Batu Api dengan Metode XRD dan SEM-EDSPerdinan Sinuhaji, Kerista Sebayang, Syahrul Humaidi, Susilawati, dan Aditia WarmanFMIPA Universitas Sumatera Utara, Medan, Sumatera Utara, IndonesiaAbstract: A research on the analysis of the crystal system and elements as well as the surface morphology of flint with methods of XRD and SEM-EDS. Flint has a hexagonal crystal system with lattice parameters, a = 4.8850 Å, b = 4.8850 Å and c = 5.3713 Å and  =  = 90o, 120o with  = density  = 3. 957 gr/cm3. Flint from Ende-Flores NTT has elements: oxygen (O) 47.56 Mass%, magnesium (Mg) 6:42 Mass%, aluminium (Al) 5:50 Mass%, silica (Si) 30.63 Mass%, and fe-rum (Fe) 9.90 Mass% with square microstructural irregular, uniform solids.Keywords: flint, elemental composition, microstructure and crystal systemEmail: perdinansinuhaji@gmail.com
