Drying ceramic products using induced ultra-high frequency electrical energy

(a). The time required to dry a test specimen by the use of ultra-high frequency induced current until shrinkage ceases is only thirty percent of the time required when heat is supplied by resistance wire heating coils.

(b). It is possible, with the use of the ultrahigh frequency energy, to dry complicated shapes evenly over their cross sections, which will enable much more rapid and safe drying of these shapes.

(c). The structures of the pieces are not detrimentally affected by induced current, and the rapid drying of this method.

(d). Drying with ultra-high frequency will probably prove to be of economical value in the drying of complicated shapes when additional research has further proved the effectiveness of the use of ultra-high frequency electrical energy.
