在生产中,有不少反应属固相反应。如硅酸盐、陶瓷、粉末冶金等的生产。本文以铁氧体的形成为例,谈谈固相反应的机理及其影响因素,供有关同志参考。铁氧体,一般是指铁族的和其他一种或多种适当的金属元素的复合氧化物。其种类较多,人类最早接触到的铁氧体是主要成份为 Fe_3O_4的磁铁矿。尖晶石型铁氧体的化学式为 MFe_2O_4=MO·Fe_2O_3的复合氧化物(M 为二价金属离子)。磁铅石型铁氧体,如钡铁氧体的化学
In production, there are many reactions are solid phase reaction. Such as silicate, ceramics, powder metallurgy and other production. In this paper, the formation of ferrite, for example, to talk about the mechanism of solid-phase reaction and its influencing factors for reference by the relevant comrades. Ferrites generally refer to composite oxides of iron family and one or more other suitable metal elements. Its species are more, the earliest human exposure to ferrite is the main component of magnetite Fe_3O_4. The spinel ferrite has the chemical formula MFe_2O_4 = MO · Fe_2O_3 complex oxide (M is a divalent metal ion). Magnetite-type ferrite, such as barium ferrite chemistry
