“…They are also used to prevent or reduce damage to equipment from exposure to fire or corrosive atmospheres. 1,2 For intermittent furnaces or where rapid heating is required, use of such coatings was found to reduce fuel or power to the tune of 25-45%. The most extensively used materials in this range are asbestos, calcium silicate, mineral fiber, mica and vermiculite based insulation, fireclay or silica based insulation and ceramic fiber.…”

The main objective of this work is to study the mechanical and dielectric properties of high temperature coating insulators based on the by-product resulted from the raw kaolin treatment; this by-product represents about 21 wt% of the kaolin as commercial products. During sintering, the mineralogical phases are mainly mullite, quartz and vitreous silica besides rutile phase which is identified only at 1200 o and 1500 o C. The sample porosity decreases from 21% to 16%. Mechanical properties carried out by Young's modulus values are enhanced during calcinations from 54 to 57 GPa. Dielectric properties, in the frequency range of 10 5 -10 9 Hz, of the samples fired at 1400 o and 1500 o C show that they can be considered as insulators since they exhibit a high relative permittivity ( exp ) varying from 6.95 to 7.89 respectively. These parameters depend on glassy, quartz and mullite phases besides porous structures. Porosity affects considerably both the corrected relative permittivity ( c ) considering the large difference between  exp ,  c and the dielectric loss of the samples.
