A US laboratory will soon use a new super furnace to produce novel materials, including one that could lead to more environmentally friendly refrigerators.

One of just four Retech Model 150 Plasma Lab Furnaces in operation around the world, mainly for research, it can generate temperatures greater than 10,000 degrees Celsius (18,000 degrees Fahrenheit).

It can melt just about anything.

The furnace is located at the Ames Laboratory Materials Preparation Center, a US Department of Energy lab operated by Iowa State University.

According to the lab’s director, Larry Jones, one of its jobs will be the production of a magnetic metal alloy that responds to changing temperatures when placed in a magnetic field.
