Making iron carbide nanoparticles is a challenging process because the material is produced in a big furnace at temperatures of around 800[degrees]C, rather than in a controlled environment in a round-bottomed flask.

Some concern has been expressed by Iscor itself about the quality of the ore it would supply, but technology suppliers Denver, USA's Iron Carbide Holdings, feel that the problems can be overcome.
If it follows this path, iron carbide - originally regarded as a potential scrap substitute - will enter the race to develop new steelmaking processes on a small scale, at low capital cost, and without the environmentally problematic coke required by traditional blast-furnace technology.
Moreover, even though silicon reduces chill carbides, it doesn't necessarily reduce intercellular iron carbides. Therefore, chill-free castings still can contain plenty of troublemakers, Figure 2.
The ferrite/pearlite ratio and iron carbide percentage were evaluated at the periphery and the center of each sample.
Minimizing iron carbide formation in iron (to create an easier-to-machine condition) demands that graphite form during eutectic solidification.
A fine pearlite, which is a lamellar matrix structure composed of alternating plates of ferrite and iron carbide, enhances the cast iron hardness and strength properties.
In addition, use test cups that do not contain tellurium (Te), which causes C to precipitate as iron carbide ([Fe.sub.3]C) instead of the desired graphite.
Iron carbide and steadite are eutectic phases between iron (Fe) and carbon (C), and Fe and phosphorus (P), respectively.
The iron carbide plant being operated for Nucor Steel has fallen short of both production quantity as well as quality level.
In a tellurium cup during this phase, iron carbide and possibly a small amount of austentite are formed.
