Sposobem tym mozna otrzymac zelaziny iharu, magnezu, cynku, kadmu, miedzi, manganu, niklu, kobaltu itp. Sklad tych zelazi¬ nów moze powaznie odbiegac od podstawowego wzoru spinelowego bez obawy utraty ich ferro- magnetycznosci i tak np. stosunki molowe Fe-203 : MeO moga wynosic od 1 : 50 do- 70 :1.Stwierdzono ponadto, ze ferromagnetyczne zelaziny mozna otrzymywac w podobny sposób, wychodzac nie tylko z 7-wodorotlenku zelazo¬ wego lecz z wszelkich wodorotlenków zelazo¬ wych o rozmaitej strukturze, jak np. z ortowo- dorotlenku zelazowego poli-orto-wodorotlenku zelazowegor izo-orto-wodorotlenku zelazowego, poli-izo-orto-wodorotlenku zelazowego, z getytu itp., których otrzymywanie opisane jest obszer¬ nie w dziele A.

Zelazin kobaltu o wzorze Co (Fe02/2, (stosunek molowy C0O.F2O3 = 1 :1, a stosunek atomowy Co : Fe = 1 : 2) otrzymuje sie przez zadanie 10 czesci wagowych Y-wodo- rotlenku zelaza 4 czesciami wagowymi 6-wodne- go azotanu kobaltowego, rozpuszczonego w do¬ wolnej ilosci wody. Mieszanine miesza sie do¬ kladnie, po czym suszy w dowolnej temperatu¬ rze, a nastepnie prazy sie w temperaturze 1000°C przez jedna godzine. Uzyskany ferromagnetyczny zelazin wykazuje trwale wlasnosci magnetycznie.Przyklad II. 10 czesci wagowych Y-wo tlenku zelaza, uprzednio wysuszonego na po¬ wietrzu, miesza sie z sucha sola azotanu kobal¬ towego przez rozcieranie w mozdzierzu. Tak otrzymana mieszanine poddaje sie najpierw wstepnemu prazeniu w celu odpedzenia wody krystalizacyjnej soli kobaltowej, po czym prazy dalej jak w przykladzie I.Przyklad III. 55.6 czesci wagowych 7-wodne- go siarczanu zelazawego w postaci suchej soli miesza sie i rozciera w mozdzierzu z 27,8 czes¬ ciami wagowymi 6-wodnego azotanu kobaltowe¬ go. Uzyskana mieszanine soli wypraza sie w tyglu w piecu elektrycznym najpierw w temperatu¬ rze okolo 500°C az do ustania wydzielania sie gazów, poczym temperature podnosi sie do 900—1000°C i utrzymuje na tym poziomie przez jedna godzine.

PLPublished on December 3, 1958 ed ¥ Pate Urzed "Pa \ en \ o- / Ww \ esisfciel jjzeczypgspalltej l; yj ^ * POLISH REPUBLIC OF PEOPLE PATENT DESCRIPTION No. 41360 Alfons Krause Poznan, Poland Wlodzimierz Wolski Poznan, Poland KI. 43r * tr2 / fft nru, W / PO The method of obtaining ferromagnetic irons The patent has been in force since July 9, 1956. Patents No. 39902 and No. 40397 describe the methods of obtaining ferromagnetic irons suitable for the production of audio tapes or other products used in the art. , requiring non-decaying ferromagnetic properties. It has been found that ferromagnetic irons can be obtained simply by wetting wet or air-dried FeO.OH gel (the preparation of which is described in Patent No. 34471) with an aqueous solution salt, containing the appropriate metal cation. a large number of ferromagnetic brown to dark steel hard irons which do not require slow cooling. In this way, it is possible to obtain irons and harsh, magnesium, zinc, cadmium, copper, manganese, nickel, cobalt, etc. The composition of these irons can significantly deviate from the basic spinel formula without fear of losing their ferro-magneticity, e.g. the molar ratios of Fe-203 : MeO can range from 1:50 to 70: 1. Moreover, it has been found that ferromagnetic irons can be obtained in a similar way, starting not only from iron 7-hydroxide but from all iron hydroxides of various structures, such as e.g. from iron orthohydroxide, poly-ortho-iron hydroxide, iron iso-ortho-hydroxide, poly-iso-ortho-iron hydroxide, from goetite and the like, the preparation of which is described in detail in the work of A. Krause entitled "Catalysts and catalytic converters" Warsaw, 1952 pp. 255-303 .. It was further found that ferromagnetic irons can also be obtained directly from various zephase compounds by subjecting them directly to the salts containing the above-mentioned cations, such as cobalt , nickel, copper, etc. The method of obtaining ferromagnetic irons, either by the calcination of iron hydroxides of various structures, or by the direct elimination of iron compounds, e.g. in the form of salts with appropriate compounds, are best illustrated by the examples below. Cobalt iron of the formula Co (FeO2 / 2, (molar ratio C0O.F2O3 = 1: 1 and atomic ratio Co: Fe = 1: 2) is obtained by applying 10 parts by weight of Y-iron hydroxide with 4 parts by weight 6. - aqueous cobalt nitrate, dissolved in any amount of water, the mixture is mixed thoroughly, then dried at any temperature and then roasted at 1000 ° C for one hour. e. The obtained ferromagnetic iron exhibits permanent magnetic properties. Example II. 10 parts by weight of Y-iron oxide, previously air-dried, is mixed with the dry salt of cobalt nitrate by grinding in a mortar. The mixture thus obtained is first pre-calcined to drive off the water of crystallization of the cobalt salt, and then further calcined as in Example I. Example III. 55.6 parts by weight of ferrous 7-aqueous ferrous sulfate in dry salt form are mixed and ground in a mortar with 27.8 parts by weight of cobalt-6-aqueous nitrate. The resulting salt mixture is crucible in an electric furnace, first at a temperature of about 500 ° C. until gas evolution ceases, then the temperature is raised to 900 ° -1000 ° C. and kept at this level for one hour. In this manner, a ferromagnetic cobalt iron with permanent magnetic properties was obtained. PL
