Abstract

Przedmiotem zgłoszenia są nowe fazy typu ograniczonego roztworu stałego domieszkowanego jonami f-elektronowego metalu, które charakteryzują się tym, że f-elektronowy metal stanowi europ(III), zaś nowe fazy opisane są ogólnym wzorem Pb1-3x xEu2x(MoO4)1-3x(WO4)3X, gdzie 0 < x ? 0,1970, a oznacza wakancje w sieci krystalicznej. Zgłoszenie obejmuje też sposób wytwarzania nowych faz typu ograniczonego roztworu stałego domieszkowanego jonami f-elektronowego metalu, polegający na mieszaniu, ujednorodnianiu, wygrzewaniu i chłodzeniu. Sposób ten charakteryzuje się tym, że molibdenian(VI) ołowiu(II) w ilości większej lub równej 67,50% 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 niż 32,50% molowego. Mieszaniny praży się w temperaturze od 900 do 985°C, następnie chłodzi otrzymując produkt o ogólnym wzorze Pb1-3x xEu2x(MoO4)1-3x(WO4)3X, gdzie 0 < x ? 0,1970, a oznacza wakancje w sieci krystalicznej. Korzystnie mieszaniny molibdenianu(VI) ołowiu(II) z wolframianem(VI) europu(III) praży się w sześciu 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 a limited solid solution doped with f-electron metal ions, which are characterized in that the f-electron metal is europium (III), and the new phases are described by the general formula Pb1-3x xEu2x (MoO4) 1-3x ( WO4) 3X, where 0 <x? 0.1970, and means vacancies in the crystal lattice. The application also includes a method of producing new phases of a limited solid solution doped with f-electron metal ions, consisting of mixing, homogenizing, heating and cooling. This method is characterized in that lead (II) molybdate in an amount greater than or equal to 67.50 mol%, and less than 100.00 mol% is mixed with europium (III) tungstate in an amount greater than 0 , 00 mole% and less than or equal to 32.50 mole%. The mixtures are roasted at 900 to 985 ° C, then cooled to give the product of general formula Pb1-3x xEu2x (MoO4) 1-3x (WO4) 3X, where 0 <x? 0.1970, and means vacancies in the crystal lattice. Preferably, mixtures of lead (II) molybdate with europium (III) tungstate are calcined in six stages, 12 hours each, the samples being slowly cooled to ambient temperature and ground after each heating stage.
