Abstract

Barium hexaferrite (BaFe12O19) has attracted research attention due to its diverse applications. This study reports the synthesis of barium M-hexaferrite (BaFe12-2xCoxZnxO19) powder using co-precipitation of BaCO3 and FeCl3.6H2O powder, Co and Zn powder as a dopant material on the variation of x = 0, 0.2, 0.4, 0.6, 0.8, and 1. Results show that co-precipitation is an effective method for the synthesis of nanomaterial barium M-hexaferrites (BaFe12-2xCoxZnxO19) containing >89% of Fe elements and an average particle size of 50 nm. The DTA/TGA analyses show phase transformation at T ≤ 285°C and T = 750-840°C. The results of refinement using the Rietveld method show that the barium M-hexaferrite phase begins to form at low temperatures, with the best yield at x = 0.4. At high temperatures T > 740°C, it tends to form single-phase α-Fe2O3 (hematite). Substitution ion dopant Co/Zn only slightly changes the lattice parameters of the hexagonal basic crystal structure

共沉淀法制备钡铁氧体BaFe12-2xCoxZnxO19(0≤X≤1)的合成与表征

六铁体钡(BaFe12O19)因其广泛的应用而引起了人们的广泛关注。本研究报道了在x = 0、0.2、0.4、0.6、0.8和1的变化条件下，以BaCO3和FeCl3.6H2O粉末共沉淀，Co和Zn粉末作为掺杂材料，合成m -六铁体钡(BaFe12-2xCoxZnxO19)粉末。结果表明，共沉淀法是制备含铁量为> ~ 89%、平均粒径为50 nm的m -六铁体钡(BaFe12-2xCoxZnxO19)纳米材料的有效方法。DTA/TGA分析表明，在T≤285°C和T = 750-840°C时发生相变。Rietveld法细化结果表明，m -六铁素体钡相在低温时开始形成，在x = 0.4时产率最佳。在高温T ~ 0 ~ 740℃时，趋于形成单相α-Fe2O3(赤铁矿)。取代离子掺杂Co/Zn对六方基本晶体结构的晶格参数影响较小
