Abstract

Manganese ferrite MnFe₂O₄ was synthesized by gel combustion synthesis using tris(hydroxymethyl)aminomethane (TRIS) as a fuel upon variation of oxidizer-to-fuel ratio Ψ and characterized by XRD, Raman spectra, and vibrating sample magnetometry (VSM). The measured values of saturation magnetization M_s = 27.70 emu g^–1 and coercivity H_c = 86.87 Oe are indicative of superparamagnetiс behavior of synthesized materials. Our results also show that TRIS could be readily used as an alternative fuel to synthesize spinel ferrites through a one-step process of solution combustion synthesis.

使用TRIS作为燃料通过凝胶燃烧合成超顺磁性MnFe2O4铁氧体：氧化剂与燃料比的影响

摘要

锰铁氧体MnFe ₂ O ₄是通过凝胶燃烧合成合成的，使用三（羟甲基）氨基甲烷（TRIS）作为燃料，根据氧化剂与燃料比Ψ的变化进行合成，并通过XRD、拉曼光谱和振动样品磁强计（VSM）进行表征。饱和磁化强度M _s = 27.70 emu g ^–1和矫顽力H _c = 86.87 Oe的测量值表明合成材料的超顺磁性行为。我们的结果还表明，TRIS 可以很容易地用作替代燃料，通过溶液燃烧合成的一步法合成尖晶石铁氧体。
