What is Sponge Iron? Uses and Benefits Explained
Unlike pig iron, which is produced in blast furnaces, sponge iron is produced at relatively lower temperatures (typically between 800 to 1,200°C). Sponge iron typically contains about 90-94% iron, with the remainder consisting of impurities such as silica, carbon, sulfur, and phosphorus. Its porous structure gives it a high surface area, which ...
