“…It is often used in coatings as extender after being crushed and classified by size (average diameter between 1.5 and 9.0 μm). It is an insulating material from the electrical point of view; it has 2.650 g.cm -3 density at 25 °C (Chen et al, 2010& Lekka et al, 2009. In this experience, quartz fibers were used with average values of 1118 μm and 95 μm for length and transverse dimension, respectively (Figure 2.C).…”
