Iron Nitride Transformers To Result In More Efficient And Superior Energy Storage Options
A theoretical transformer devised by researchers from the Sandia National Laboratories has the capability to store Energy in a cheap and compressed manner. Todd Monson of the Nanoscale Sciences Department explained that his team had already discovered a method to design a special magnet which could revolutionize the working of transformers and produce a miniaturized, cost effective, high frequency transformer. It will also help in the global promotion of renewable energy sources as a better alternative to conventional exhaustible sources, and also work as an effective energy storage device.
The group processed iron nitride (γ'-Fe4N) powders by ball-milling iron powders in liquid nitrogen and subsequently in ammonia. In the next step, the iron nitride powder is physically strengthened using low-temperature field-assisted sintering technique (FAST) which generates solids from loose powders by applying heat and pressure.

Switching to the FAST method, makes it possible to construct the core of the transformer, in a matter of minutes, without disintegrating the desirable Iron Nitrides. Another key attribute of this method allows the net-shaping of parts, which implies that the Iron Nitride powders can be directly moulded into shapes such as that of transform cores without any machine action. Owing to its magnetic properties, Iron Nitride transformers can be made more condensed and lighter in comparison to conventional transformers.
Such a design also greatly boosts the efficiency and power handling capacity of the transformer. According to the team, the system can vastly enhance the energy storage process and power electronic equipment. The research work was supported by the Department of Energy's (DOE) Energy Storage Program in the Office of Electricity Delivery and Energy Reliability, and is a part of the collaborative projects among the Sandia National Laboratories, University of California, Irvine and the Arizona State University.
