Using An AC Field Strengthens Ceramics

Caption

By applying a 60 Hertz alternating current field, researchers were able to reduce the grain size of ceramics by 63 percent -- and eliminated porosity at 1,250 degrees Celsius, as opposed to the 1,500 degrees Celsius needed without the electric field.
