HOYOS PALACIO, Lina Marcela; ESPINEL BLANCO, Edwin  e  QUINTERO MARTINEZ, Yeixon. Physiochemical characterization of quartz in the municipality of La Playa de Belén-North Santander department. Tecnura [online]. 2015, vol.19, n.45, pp.41-51. ISSN 0123-921X.  https://doi.org/10.14483/udistrital.jour.tecnura.2015.3.a03.

Quartz is a silicate, available in a variety of geological conditions, it appears in many igneous and metamorphic rocks, and it is a major constituent of granite pegmatite. Among minerals, quartz is the closest to a pure chemical compound and has constant physical properties, and due to their applications and uses it becomes a material that contributes to improving the living conditions of man. For that reason, it is necessary to know their properties to propose optimal applications. This work presents the physicochemical characterization of quartz in the municipality of La Playa de Belen (North Santander Department, Colombia) using elementary techniques through studies to establish the physical and chemical properties of this mineral. Techniques such as scanning electron microscopy (SEM) with disperse energy analyzer (EDS), X-ray diffraction (XRD), thermogravimetric (TGA) and differential thermogravimetric analysis (DTG) were used. The compositional, chemical and morphological characteristics are obtained, and the thermal behavior is evaluated according to the composition.
