A variation in the conditions of the synthesis allows for the adjustment of the mean size of the hollow iron particles. Iron powders were obtained by this technique, starting from the aqueous solution of iron nitrate of two different concentrations: 10 and 20 wt.%. This was followed by a reduction in hydrogen. An increase in the concentration of the solution increased the mean particle size from 0.6 to 1.0 microns and widened particle size distribution, but still produced hollow particles. Larger particles appeared problematic for the reduction, although admixture of iron oxides did not decrease the microwave permeability of the material. The paraffin wax-based composites filled with obtained powders demonstrated broadband magnetic loss with a complex structure for lesser particles, and single-peak absorption for particles of 1 micron. Potential applications are 5G technology, electromagnetic compatibility designs, and magnetic field sensing.<\/jats:p>","DOI":"10.3390\/s22083086","type":"journal-article","created":{"date-parts":[[2022,4,19]],"date-time":"2022-04-19T02:39:31Z","timestamp":1650335971000},"page":"3086","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["The Size Dependence of Microwave Permeability of Hollow Iron Particles"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5083-6058","authenticated-orcid":false,"given":"Anastasia V.","family":"Artemova","sequence":"first","affiliation":[{"name":"Institute for Theoretical and Applied Electromagnetics RAS, Moscow 125412, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1118-0070","authenticated-orcid":false,"given":"Sergey S.","family":"Maklakov","sequence":"additional","affiliation":[{"name":"Institute for Theoretical and Applied Electromagnetics RAS, Moscow 125412, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexey V.","family":"Osipov","sequence":"additional","affiliation":[{"name":"Institute for Theoretical and Applied Electromagnetics RAS, Moscow 125412, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dmitriy A.","family":"Petrov","sequence":"additional","affiliation":[{"name":"Institute for Theoretical and Applied Electromagnetics RAS, Moscow 125412, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Artem O.","family":"Shiryaev","sequence":"additional","affiliation":[{"name":"Institute for Theoretical and Applied Electromagnetics RAS, Moscow 125412, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Konstantin N.","family":"Rozanov","sequence":"additional","affiliation":[{"name":"Institute for Theoretical and Applied Electromagnetics RAS, Moscow 125412, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrey N.","family":"Lagarkov","sequence":"additional","affiliation":[{"name":"Institute for Theoretical and Applied Electromagnetics RAS, Moscow 125412, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,4,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"267","DOI":"10.1016\/j.jallcom.2017.02.250","article-title":"Corrosion-resistive magnetic powder Fe@SiO2 for microwave applications","volume":"706","author":"Maklakov","year":"2017","journal-title":"J.
