    • The invention concerns the preparation of acicular particles of mixed oxalates of iron and of one or more metals of the group consisting of cobalt, nickel, copper, manganese, zinc, magnesium and cadmium. The method consists in preparing a first solution containing cations of iron and of the divalent metal or metals, and a second solution containing oxalic acid, one of the said solutions further containing Cl.sup.- and SO.sub.4.sup.2.sup.- anions and at least the second solution containing alcohol with preferably a light hydrocarbon. The first solution is poured very slowly (1 drop every 10 seconds) into the second one, conveniently at temperature below 0.degree. C, while the latter is strongly stirred. The concentration in alcohol is preferably maintained at at least 50% in the second solution during the whole pouring process which should be effected with at least a slight excess of oxalic acid. The particles obtained may be treated for the preparation of solid solutions of oxides of iron and of the divalent metal or metals for the manufacture of magnetic tapes and the like.
    • 本发明涉及制备铁和由钴,镍,铜,锰,锌,镁和镉组成的组中的一种或多种金属的混合草酸铁的针状颗粒。 该方法包括制备含有铁阳离子和二价金属或金属的第一溶液和含有草酸的第二溶液,所述溶液中的一种还含有Cl - 和SO42-阴离子,并且至少第二溶液 含有优选轻质烃的醇的溶液。 将第一溶液非常缓慢地(在每10秒滴1次)倒入第二溶液中,方便地在低于0℃的温度下,同时将其强烈搅拌。 在整个浇注过程中,醇中的浓度优选在第二溶液中保持至少50%,这应该至少少量过量的草酸进行。 所获得的颗粒可以用于制备铁氧化物和二价金属或金属的固溶体以制造磁带等。

    • The invention concerns solid solutions of oxides of iron and of a divalent metal other than cobalt Co.sup.2+ or, alternatively, of iron and of more than one divalent metal, including cobalt. Besides Co, the divalent metals may be Ni, Cu, Mn, Zn, Mg and Cd. Such solutions are prepared by precipitating a mixed oxalate containing iron and the other divalent metal or metals desired. This mixed oxalate is decomposed by heating it in open air at a progressively increasing temperature until carbon is eliminated but without forming rhomboedric oxide .alpha.-Fe.sub.2 O.sub.3. The pyrolyzed product is treated by hydrogen and steam at an elevated temperature to obtain a substituted magnetite, and this magnetite is oxidized in air at such a temperature as to avoid formation of .alpha.-Fe.sub.2 O.sub.3.
    • 本发明涉及铁的氧化物和钴Co 2+以外的二价金属,或者铁和多于一种二价金属(包括钴)的固溶体。 除Co之外,二价金属可以是Ni,Cu,Mn,Zn,Mg和Cd。 通过沉淀含铁的混合草酸盐和所需的其它二价金属或金属来制备这些溶液。 这种混合的草酸盐在逐渐增加的温度下在露天加热直到碳被除去但不形成氧化锆的α-Fe 2 O 3来分解。 热解产物在高温下用氢气和蒸汽处理以获得取代的磁铁矿,并且该磁铁矿在空气中被氧化以避免形成α-Fe 2 O 3。
