Cost savings in the metallurgical industry


Metallurgical silicon carbide is mainly used for deoxidation and recarburation of cast iron and steel. When added along the smelting process, silicon carbide manufactured by Navarro SiC disgregates into its fundamental components; carbon produces the recarburation of iron, while silicon facilitates deoxidation of the metal. This exothermic decomposition reaction rises the temperature of the melt, reduces the appearance of pores, provides energy savings and allows a better graphite distribution in cast iron.

Silicon carbide acts as a fuel, and provides benefits by improving the quality and machinability of steels and cast irons and extending the life of the furnace lining. It also improves the recovery of secondary elements such as manganese and chromium, and produces slags with a consistency and melting point that allow a most efficient removal from the furnace.

The use of silicon carbide produced by Navarro SiC results in a significant cost reduction due to its properties as a slag reductor, energy contribution, improvement of the characteristics of steel and replacement of other additives such as ferrosilicon.

Our portfolio


For its application in the metallurgical industry, Navarro SiC manufactures a range of products with a silicon carbide content varying from 45 to over 90%, to be used either as a direct additive in iron and steel foundries, or to be integrated in the manufacturing of briquettes.
