Ferrite conductivity
Did you know?
WebFerrite is a polycrystal, sintered material with high electrical resistivity. The high resistance of ferrite makes eddy current losses extremely low at high frequencies. Therefore, unlike … WebFerrite powder is mixed with binder solution, and then dispersed using three-roll mills. The binder solution is composed of ethylcellulose and an organic solvent. The ferrite paste and a half turn of winding conductive paste are printed alternately by screen-printing. The printed thick film is then cut into green chips.

Ferrite magnets are non-conductive aferromagnetic ceramic compounds derived from iron oxides such as Haematite (Fe203) or Magnetite (Fe304) and other metal oxides such as Barium and Strontium. The first studies on this material date back to the 1940s, but actual applications were recorded only from the early 1950s.
