Ferrites as Non‐Toxic Pigments for Eco‐Friendly Corrosion Protection Coatings

Protective and Suppressing Electromagnetic Interference Properties of Epoxy Coatings Containing Nano-Sized NiZn Ferrites

“…Composite coatings filled with magnetic ferrites reduce the radiation caused by the use of electromagnetic sources in the environment and can be used to protect electronic devices against external unwanted electromagnetic fields. Therefore they have been recently investigated in many studies that concentrate on their microwave absorbing properties (Yusoffa and Abdullah, 2004;Dosoudil et al, 2006;Abbas et al, 2007;Bueno et al, 2008;Zhao et al, 2009;Kharissova et al, 2015;Grigoriev et al, 2016;Suarez et al, 2019). The properties of ferrite composite materials obtained by mixing ferrite particles with a resin can also be partially controlled by processing conditions.…”

“…The anticorrosive properties of some micro-and nano-sized ferrite pigments have been documented (Sekine and Kato, 1986;Abu Ayana et al, 1997;Kalendova, 2000;Zubielewicz and Gnot, 2004;Kalendova and Vesely, 2008;Miszczyk and Darowicki, 2011;Chaudhry et al, 2015Chaudhry et al, , 2017Grigoriev et al, 2016). Although conventional anticorrosive pigments containing lead or hexavalent chromium (VI) (zinc chromate) cannot be used formally these days due to the environmental and human hazard, there is still a need for effective active anti-corrosive pigments.…”
