Here are presented the elaboration and characterization of a composite material with
an atomized ceramic paste and flying ashes product of the coal combustion. The
samples consist of prismatic tiles of 10x5x1 cm, formed by uniaxial pressing at 30
bars, made for mixes with a percentage weight of 90-10, 80-20, 70-30, 60-40 and
50-50, where the majority phase corresponds to the atomized ceramic paste. The
drying process was conducted at room temperature for 12 hours and then in drying
oven at 110 ° C for 24 hours. The sintering was carried out in gradient electric
muffle at a maximum temperature of 1150 °C. According to the porous morphology
and mechanical properties found for samples, this can be used as ceramic coatings
with thermal isolation qualities for edifications in tropical weather like the
metropolitan area of Cucuta, North Santander (Colombia)
