what is the difference between sponge iron and pig iron?
237114
The source of both pig iron and sponge iron are iron ore. In case of pig iron, the ore is reduced and melt in the blast furnace and the preliminary product is liquid iron, which solidifies to pig iron. On the other hand, sponge iron is achieved by reduction of iron ore in a solid state process. The ore is never melted.

As nouns the difference between rust and iron is that rust is the deteriorated state of iron or steel as a result of moisture and oxidation while iron is (uncountable) a common, inexpensive metal, often black in color, that rusts, is attracted by magnets, and is used in making steel.

Ductile Iron vs Steel. ... Note: Ductile iron with its carbon content of 3.0%-3.9% has a higher carbon content than cast steel which normally has a carbon content of 0.08%-0.60%. Tensile Strength. While there is no large difference when it comes to tensile strength, ductile iron has the greater yield strength (40 ksi).

The key difference between red and black iron oxide is that the red iron oxide occurs as a red-brown solid whereas the black iron oxide occurs as a solid black powder. ... In other words, red iron oxide has an iron with the oxidation number +3 and black iron oxide has both +2 and +3 oxidation states.

The raw materials used to produce pig iron in a blast furnace are iron ore, coke, sinter, and limestone. Iron ores are mainly iron oxides and include magnetite, hematite, limonite, and many other rocks. The iron content of these ores ranges from 70% down to 20% or less.

All steel contains iron, but it also contains carbon. ... The primary difference between iron and steel is that the former is a metal, whereas the latter is an alloy. Iron is simply a metal element that occurs naturally on Earth. In comparison, steel is a man-made alloy that's made by mixing iron and carbon together.

Safe cookware is BOTH PTFE and PFOA free. It can't be one or the other - it has to be both. PTFE is teflon - it has long been established that it kills birds. PFOA is used to adhere nonstick coatings (whatever they might be) to pans - it is also toxic.

Like gray cast iron, white cast iron features many small fractures. The difference is that white cast iron features cementite below its surface, whereas gray cast iron features graphite below its surface. The graphite creates the appearance of a gray color, while the cementite creates the appearance of a white color.

Actually, the basic distinction between the two is simple: Cast iron is iron that has been melted, poured into a mold, and allowed to cool. Wrought iron is iron that has been heated and then worked with tools. In fact, the term “wrought” derived from the past participle of the word “worked.”
