One of the key factors that enables monolithic refractories to withstand chemical attack is their high melting point. These materials are designed to have a melting point significantly higher than the temperature of the molten metal or slag they are exposed to. This prevents the refractory from melting or deforming when in contact with the hot molten substances. In addition to their high melting point, monolithic refractories are formulated with materials that have excellent chemical resistance. They are often composed of a combination of oxides, such as alumina, magnesia, and zirconia, which have a strong affinity for oxygen and form stable compounds. This allows the refractory to form a protective oxide layer on its surface when exposed to molten metals and slag, effectively shielding it from chemical attack. Furthermore, the dense and compact structure of monolithic refractories plays a crucial role in their resistance to chemical attack. The absence of joints and seams minimizes the chances of molten metals and slag infiltrating the refractory and causing chemical reactions. This dense structure also reduces the porosity of the material, making it less permeable to aggressive substances. Moreover, manufacturers often add specialized additives to monolithic refractories to enhance their chemical resistance. These additives can include fibers, binders, and corrosion inhibitors, which further improve the refractory's ability to withstand chemical attack. In conclusion, monolithic refractories are designed to withstand chemical attack from molten metals and slag through their high melting point, chemical-resistant composition, dense structure, and specialized additives. These properties allow them to maintain their integrity and performance even in the harshest environments, making them an ideal choice for applications involving high-temperature and corrosive substances.
