5203 |a"Studies of the mechanism of the formation of lead hexaferrite from its constituent oxides have been conducted. The reactions were studied by differential thermal analysis, thermogravimetric analysis, X-ray diffraction procedures and by magnetic susceptibility measurements. It was found that the nature of the intermediate product(s) was dependent upon the technique of mixing, and the time and temperature of heating. There is an indication that there may be considerable variations in the temperature dependence of the various possible intermediate reactions. A kinetic model describing the behaviour of the system is postulated. The intermediate compounds observed were 2PbO.Fe2O3 and PbO.2Fe2O3. The latter can be distinguished from the structurally-similar PbO.6Fe2O3 by the use of magnetic susceptibility measurements"--Abstract, p. 1.
