Evolution of magnetic phases located in Boyacá clays subject to high temperatures
In this paper we analyze clay samples obtained from the region of Tunja Boyacá to study the effect of heating temperature in the color of these materials and at the same time as indicative of the nature and distribution of constituents iron oxide Fe2 O3 .
