原始语种摘要: Abstract(#br)The mineralogical and chemical characteristics, based on X-ray diffraction (XRD) and scanning electron microscopy, of a kaolin known as DD3, from eastern Algeria were examined in the present study.(#br)The results showed that kaolin DD3 has an alumina content of 39%. The SiO 2 /Al 2 O 3 molar ratio of 2.14 is close to that of a pure halloysite. The hematite concentration is relatively large and the flux oxides ratios remain as acceptable impurities. Microscopic observations showed a predominant tubular halloysite phase, flattened hexagonal platelets corresponding to the presence of kaolinite and its polymorphs (nacrite, dickite), and hydrated alumina. The SiO 2 /Al 2 O 3 molar ratio and tubular DD3 suggest possible uses in technical ceramics and nanotechnology...
