Generally, the production of structural ceramics is very aggressive towards the refractories, considering the type of fuel, atmosphere of the furnace, heavy load on the parts, high soaking times and firing cycles.

To solve a large part of these problems, Estiva is a partner of Resco/Paco (USA) for supplying of special refractory based on pyrophyllite. These products are manufactured by extrusion in various formulations for different applications and present a performance far superior to the silicon-alumina refractories commonly used in the production of bricks and tiles.
