Abstract

"COMPOSTO PRECURSOR DE ALUMINATO DE ALCALINO-TERROSO OU DE TERRA RARA ALUMINATO DE ALCALINO-TERROSO OU DE TERRA RARA, PROCESSO DE PREPARAçãO DO COMPOSTO PRECURSOR, TELA DE PLASMA, LáMPADA TRICROMáTICA E DIODO ELETROLUMINESCENTE". A presente invenção se refere a um composto precursor de aluminato de alcalino-terroso ou de terra rara da invenção de fórmulas: a(M¬ 1¬O).b(MgO).c(A1~ 2~O~ 3~) nos quais M¬ 1¬ designa um alcalino-terroso e M¬ 2¬ o ítrio ou o cério e o térbio em combinação a, b e c são números inteiros ou não, verificando as relações: 0,25 <243> a <243> 4; 0 <243> b <243> 2 e 0,5 <243> c <243> 9 cristalizado sob a forma de uma alumina de transição; constituído por partículas esféricas e quimicamente homogêneas; e estas partículas comportam poros cujo diâmetro médio é de pelo menos 10 nm. Ele é obtido por um processo no qual forma-se uma mistura líquida que comporta compostos do alumínio e outros elementos que entram na composição do precursor; seca-se por atomização a dita mistura e calcina-se o produto a uma temperatura compreendida entre 700<198>C e 950<198>C. Por calcinação posterior do produto assim obtido, obtém-se um aluminato de alcalino-terroso ou de terra rara.
