Or Iron Carbid is a mixture of iron, carbon, or, more precisely, an intermediate transitional metal carbide having the molecular formula F3C. It weighs 6.67% and 93.3% respectively. It is a gray-white crystal powder with a relative density of 7.694. It is insoluble when dissolved in hot, cold water and dilute acid. But it is soluble in hot concentrated hydrogen chloric acid to make mixtures with hydrogen, methane and other complex hydrocarbons. Do not react with dry oxygen. Iron oxide and carbon can be formed by oxidizing in moist air. It has an orthorhombic structure. It is a soft and fragile material and, in its natural form, is classified as ceramic. This is why it is an integral part of black metalurgisty.
What does Fe3C mean?
Cementite also contains Fe3C, iron carbide.
How do you make cementite?
Primary cementite
When the liquid alloy of iron-carbon alloy (hypereutectic yellow cast iron), is cooled below the liquidus, the cementite precipitates.
Eutectic cemented cementite:
The ledeburite structure has a point strip cementite that is uniformly distributed in the austenite matrix. This is called eutectic or eutectic cemite.
Preeutectoid phase, cementite:
Alloys with hypoeutectoid/hypereutectoid composition are always precipitated with a decrease in temperature. This is the proeutectoid Phase. Because of the differences in forming conditions, proeutectoid morphology can be divided into three types, block, reticulate, and Widmanstatten structures.
Eutectoid cementite:
Eutectoid cementite refers to the cementite found in pearlite.
Secondary cementite
When iron-carbon alloys are slow cooled, such as hypoeutectic iron, hypoeutectic iron cast iron, and hypereutectic iron cast iron), the carbon content in austenite becomes saturated. The cementite will then precipitate along austenite’s grain boundary, with a network distribution in microstructure. Secondary cementite is the cementite formed from austenite.
Tertiary cementedite:
When the equilibrium cooling temperature of industrial pure iron drops below the solid solution line for carbon in iron (FeC equilibrium diagram Q line), then the solubility in carbon in ferrite reaches saturation. The temperature decreases again and the tertiary cemented from ferrite. The tertiary ferrite cementite is precipitated from the ferrite-grain boundary. It generally occurs intermittently along the line of ferrite grain border because it is so small.
It refers only to those that exist outside of the mechanical mixture (structure), such a pearlite (eutectoid) or ledeburite.
