Abstract

Oksysól w dwuskładnikowym układzie wolframianu(VI) metalu-molibdenianu(VI) pierwiastka ziem rzadkich, charakteryzuje się tym, że układ dwuskładnikowy oznacza wolframian(VI) kobaltu(II)-molibdenian(VI) prazeodymu(III) lub molibdenian(VI) neodymu(III) lub molibdenian(VI) samaru(III) lub molibdenian(VI) europu(III) lub molibdenian(VI) gadolinu(III) lub molibdenian(VI) terbu(III) lub molibdenian(VI) dysprozu(III), a oksysól ma ogólny wzór CoRE2MoWO10 gdzie RE oznacza prazeodym lub neodym lub samar lub europ lub gadolin lub terb lub dysproz. Sposób wytwarzania oksysoli w dwuskładnikowym układzie wolframianu(VI) metalu-molibdenianu(VI) pierwiastka ziem rzadkich, polegający na mieszaniu, ujednoradnianiu i wygrzewaniu otrzymanych mieszanin, charakteryzuje się tym, że wolframian(VI) kobaltu(II) miesza się z molibdenianem(VI) prazeodymu(III) lub molibdenianem(VI) neodymu(III) lub molibdenianem(VI) samaru(III) lub molibdenianem(VI) europu(III) lub molibdenianem(VI) gadolinu(III) lub molibdenianem(VI) terbu(III) lub molibdenianem(VI) dysprozu(III) w stosunkach molowych w % jak 50:50. Mieszaniny ogrzewa się w temperaturze 800-1000°C, najlepiej w 8 etapach po 12 godzin każdy. Po każdym etapie próbki schładza się wolno do temperatury otoczenia, otrzymując produkt o wzorze CoRE2MoWO10 gdzie RE oznacza prazeodym lub neodym lub samar lub europ lub gadolin lub terb lub dysproz.Oxysol in the two-component rare-earth metal-molybdate (VI) tungstate system is characterized in that the two-component system is cobalt (II) tungstate (VI) molybdate (VI) praseodymium (III) or neodymium (VI) molybdate (VI) III) or samarium (III) molybdate or VI (europium III) molybdate or gadolinium (III) molybdate or terbium (III) molybdate or dysprosium molybdate (VI), and oxysole has the general formula CoRE2MoWO10 where RE is praseodymium or neodymium or samarium or europium or gadolinium or terbium or dysprosium. The method of producing oxysols in a two-component rare-earth metal-molybdate (VI) tungstate system, consisting of mixing, homogenizing and annealing of obtained mixtures, characterized by the fact that cobalt (II) tungstate is mixed with molybdate (VI) praseodymium (III) or molybdate (VI) neodymium (III) or molybdate (VI) samarium (III) or molybdate (VI) europium (III) or molybdate (VI) gadolinium (III) or molybdate (VI) terbium (III) or molybdate (VI) dysprosium (III) in molar ratios in% as 50:50. The mixtures are heated at 800-1000 ° C, preferably in 8 stages of 12 hours each. After each step, the samples are slowly cooled to ambient temperature to give a product of the formula CoRE2MoWO10 where RE is praseodymium or neodymium or samarium or europium or gadolinium or terbium or dysprosium.
