  • Open porosity makes refractory bricks products susceptible to corrosion as gaseous and liquid corrosive substances can penetrate into their material structure. The penetration of the corrosive substances in the material structure can in turn cause physicochemical reactions that destroy a refractory product z. B. lead due to a material dissolution.
  • the products resulting from the chemical reactions often have other properties, e.g. a different coefficient of thermal expansion than the refractory material itself, which leads to thermal stresses and thus cracking and microcracking. This can lead to flaking in the refractory product, as the crack and microcracks weaken the material structure. Overall, the result is thus an impairment of the long-term stability of the ceramic body.
  • Refractory products containing chromium oxide which is particularly resistant to corrosion, are known in the prior art.
