Abstract

Przedmiotem zgłoszenia są nowe fazy typu ograniczonych roztworów stałych domieszkowanych jonami f-elektronowego metalu i jonami d-elektronowego metalu, które charakteryzują się tym, że f-elektronowy metal stanowi europ(III), a d-elektronowy metal stanowi mangan lub kobalt, przy czym fazy mają ogólny wzór Ca0,9934-3xM0,0066 xEu2X(MoO4)1-3x(WO4)3X, gdzie 0 < x ? 0,2222, M oznacza Mn lub Co, a oznacza wakancje w sieci krystalicznej. Zgłoszenie obejmuje też sposób wytwarzania nowych faz typu ograniczonych roztworów stałych, domieszkowanych jonami f-elektronowego metalu i jonami d-elektronowego metalu, który polega na mieszaniu, ujednorodnianiu, wygrzewaniu i chłodzeniu. Sposób ten charakteryzuje się tym, że molibdenian(VI) wapnia w ilości większej lub równej 59,00% molowego, a mniejszej niż 100,00% molowego miesza się z wolframianem(VI) europu(III) w ilości większej niż 0,00% molowego, a mniejszej lub równej 40,00% molowego oraz molibdenianem(VI) manganu(II) lub molibdenianem(VI) kobaltu(II) w ilości równej 1,00% molowego. Mieszaniny praży się w temperaturze od 900 do 1170°C, następnie chłodzi otrzymując produkt o ogólnym wzorze Ca0,9934-3xM0,0066 xEu2x(MoO4)1-3X(WO4)3x, gdzie 0 < x ? 0,2222, M oznacza Mn lub Co, a oznacza wakancje w sieci krystalicznej. Korzystnie mieszaniny molibdenianu(VI) wapnia z wolframianem(VI) europu(III) i molibdenianem(VI) manganu(II) lub molibdenianem(VI) kobaltu(II) praży się w siedmiu etapach, po 12 godzin każdy, przy czym po każdym etapie ogrzewania próbki schładza się wolno do temperatury otoczenia i rozciera.The subject of the application are new phases of the type of limited solid solutions doped with f-electron metal ions and d-electron metal ions, which are characterized in that the f-electron metal is europium (III) and the d-electron metal is manganese or cobalt, with the phases have the general formula Ca0.9934-3xM0.0066 xEu2X (MoO4) 1-3x (WO4) 3X, where 0 <x? 0.2222, M means Mn or Co, and means vacancies in the crystal lattice. The application also includes a method of producing new phases of the type of limited solid solutions doped with f-electron metal ions and d-electron metal ions, which involves mixing, homogenizing, heating and cooling. This method is characterized in that calcium molybdate in an amount greater than or equal to 59.00 mol% and less than 100.00 mol% is mixed with europium (III) tungstate in an amount greater than 0.00% molar and less than or equal to 40.00 mol% and molybdate (VI) manganese (II) or molybdate (VI) cobalt (II) in an amount equal to 1.00 mol%. The mixtures are roasted at 900 to 1170 ° C, then cooled to give the product of the general formula Ca0.9934-3xM0.0066 xEu2x (MoO4) 1-3X (WO4) 3x, where 0 <x? 0.2222, M means Mn or Co, and means vacancies in the crystal lattice. Preferably, mixtures of calcium molybdate (VI) with europium (III) tungstate and manganese (VI) molybdate or cobalt (II) molybdate are roasted in seven stages, 12 hours each, after each stage heating the sample is slowly cooled to ambient temperature and ground.
