D\u00e8 na Magnetan C\u00e8ramach?<\/strong><\/span><\/h2>\n

Tha magnetan c\u00e8ramach, ris an canar cuideachd magnetan ferrite, nan magnetan seasmhach cruaidh agus briseadh-d\u00f9bailte a chaidh an d\u00e8anamh le measgachadh de oxide iarainn le barium no strontium carbonate. Tha iad m\u00f2r-ch\u00f2rdte oir tha iad saor agus a' seasamh an aghaidh caitheamh agus demagnetization. Faodaidh tu magnetan c\u00e8ramach a chleachdadh ann an iomadh tagradh gn\u00ecomhachais leithid motaran DC, sgaradairean magnetach, agus sensaran c\u00e0r. Le cuideam, tha magnetan ferrite a' gabhail os cionn 75% de chaitheamh magnetach na cruinne.<\/p>\n

D\u00e8anamh Magnetan C\u00e8ramach<\/strong><\/span><\/h2>\n

Tha magnetan c\u00e8ramach air an d\u00e8anamh le teicne\u00f2las p\u00f9dar. Tha thu a' measgachadh na stuthan amh, a tha mar as trice oxide iarainn agus strontium carbonate, agus an uairsin an teasachadh gu timcheall air 1800-2000\u00b0F. Tha am pr\u00f2iseas seo a' toirt a-mach freagairt cheimiceach a bhios a' d\u00e8anamh stuth ferrite. Tha an ferrite an uairsin air a lughdachadh gu p\u00f9dar m\u00ecn le bhith a' cleachdadh milling uisge. Tha am p\u00f9dar air a thogail airson a bhith air a bhogadh no air a tharraing mar slurry fliuch a-steach do mhodail gus a chruthachadh.<\/p>\n

Ann an bogsa fliuch, tha thu a' cruachadh an slurry ann an modail, gu tric le raon magnetach air a chur an s\u00e0s. Tha seo a' cur ri bhith a' d\u00e8anamh nan p\u00ecosan ferrite, gus am bi an magnet a' faighinn na feartan magnetach a tha thu ag iarraidh. An ceum mu dheireadh 's e sin a' sinteradh an stuth aig mu 2000\u00b0F. Tha am pr\u00f2iseas seo a' toirt air falbh uisge sam bith fhathast agus a' cruthachadh magnet tiugh, seasmhach. Tha an magnet briseadh-d\u00f9bailte an uairsin air a ghearradh gu meud le wheels diamaint oir tha e cho cruaidh nach urrainn do dh' innealan \u00e0bhaisteach a chruthachadh.<\/p>\n
