Cr and carbon BTMCs are a series of intermetallic compounds with specific chemical formulas that share certain unique characteristics. In this study, we used polycrystalline powders of chromium and carbon as precursors and synthesised single-phase bulk Cr<jats:sub>7<\/jats:sub>C<jats:sub>3<\/jats:sub> (orthorhombic, space group: <jats:italic>Pnma<\/jats:italic>) with high density and good crystallinity using a high-temperature and high-pressure quenching method (HTHPQM). We studied the material properties and electronic structures of Cr<jats:sub>7<\/jats:sub>C<jats:sub>3<\/jats:sub> with both experimental measurements and density functional theory <jats:italic>ab intio<\/jats:italic> simulations and found that Cr<jats:sub>7<\/jats:sub>C<jats:sub>3<\/jats:sub> is a conductor with an electrical conductivity (2.32 \u00d7 10<jats:sup>\u22123<\/jats:sup> \u03a9 m), relatively high compaction (97.2%), excellent thermostability (oxidation at 1175 K), and a magnetic phase transition from paramagnetism to soft ferromagnetism around 50 K, and the electromagnetic properties are chiefly due to the abundance of the 3<jats:italic>d<\/jats:italic> electrons of Cr, and the orbital hybridisation between C and Cr with their 2<jats:italic>p<\/jats:italic> and 3<jats:italic>d<\/jats:italic> electrons is the reason for the crystal structure and high thermostability. Therefore, the synthesised Cr<jats:sub>7<\/jats:sub>C<jats:sub>3<\/jats:sub> is a multifunctional material with promising application prospects, and HPHTQM is a simple and effective method for preparing samples.<\/jats:p>","DOI":"10.1088\/1361-648x\/adaf65","type":"journal-article","created":{"date-parts":[[2025,1,28]],"date-time":"2025-01-28T22:56:46Z","timestamp":1738105006000},"page":"155701","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Electromagnetism and thermostability of Cr<sub>7<\/sub>C<sub>3<\/sub> synthesised with high-temperature and high-pressure quenching method"],"prefix":"10.1088","volume":"37","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5144-2808","authenticated-orcid":true,"given":"Zekun","family":"Yu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chao","family":"Zhou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9330-1384","authenticated-orcid":true,"given":"Kuo","family":"Bao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhaoqing","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pinwen","family":"Zhu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiang","family":"Tao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9664-848X","authenticated-orcid":true,"given":"Tian","family":"Cui","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"266","published-online":{"date-parts":[[2025,2,27]]},"reference":[{"key":"cmadaf65bib1","doi-asserted-by":"publisher","first-page":"512","DOI":"10.1007\/s11106-018-9923-y","article-title":"Features of chromium carbide synthesis using different forms of carbon","volume":"56","author":"Pinchuk","year":"2018","journal-title":"Powder Metall.
