| description | Physical properties of clay minerals are essential in the evaluation for applications and new potential uses of geological materials. This study presents results of optical, electrical, structural, compositional and morphological analysis of Hillite (0.967) / Chlorite (0.013) / Hematite (0.02) clay mineral extracted from the Machado mountain region in the municipality of Tarairá, department of Vaupés, Colombia. The extracted clay was subjected to treatments to separate it from the others geological compounds before the characterization process. The observed platy morphology allowed to perform a size grain analysis which confirmed the clay-extraction. Particles with 0.8- 1.4 mm diameter and two pseudo-modes distribution in the area histogram were found. The bimodal distribution is assumed to be caused due to the differences between periodic ages of formation of the minerals in the extraction region. Structurally, we found a monoclinic structure with residues of triclinic polymorphous and Hexagonal scalenohedral segregated structures. The XRD analysis was based in the EDS measurements, given the stoichiometry of the sample. Also, a big absorption in the optical UV-range with an effective band gap in the clay to 2.852(8) eV was found. The electrical properties of the clay showed a strong non-linear insulator behavior. Electrical losses by polarizing the sample were decreased by a previous heating. Finally, the complete physical properties analysis allowed to introduce this material as an inexpensive, time efficient insulator. |

Las propiedades físicas de los minerales arcillosos son esenciales en la evaluación de aplicaciones y nuevos usos potenciales de materiales geológicos. Este estudio presenta resultados de análisis óptico, eléctrico, estructural, composicional y morfológico de mineral de arcilla Illita (0.967) / Clorita (0.013) / Hematita (0.02) extraído de la región montañosa de Machado en el municipio de Tarairá, departamento de Vaupés, Colombia. La arcilla extraída fue sometida a tratamientos para separarla de los demás compuestos geológicos antes del proceso de caracterización. La morfología laminar observada permitió realizar un análisis de tamaño de grano que confirmó la extracción de arcilla. Se encontraron partículas con un diámetro de 0,8 a 1,4 mm y dos pseudo-modos de distribución en el histograma de áreas. Se supone que la distribución bimodal se debe a las diferencias entre las edades periódicas de formación de los minerales en la región de extracción. Estructuralmente, encontramos una estructura monoclínica con residuos de estructuras segregadas polimorfas triclínicas y escalenoédricas hexagonales. El análisis XRD se basó en las medidas de EDS, dada la estequiometría de la muestra. Además, se encontró una gran absorción en el rango óptico UV con un intervalo de banda efectivo en la arcilla a 2.852 (8) eV. Las propiedades eléctricas de la arcilla mostraron un fuerte comportamiento aislante no lineal. Las pérdidas eléctricas por polarización de la muestra fueron disminuidas por un calentamiento previo. Finalmente, el análisis completo de las propiedades físicas permitió introducir este material como un aislante económico y eficiente en el tiempo.
