Abstract
Procedeul de obtinere a trioxidului de bismuit pur, conform inventiei, consta în dizolvarea bismutului tehnic sau a unui aliaj de Bi-Pb în acid azotic, separarea plumbului în prima faza cu acidul sulfuric, filtrarea suspensiei si precipitarea oxidului de bismuit cu o solutie concentrata de hidroxid de sodiu în mediu de clorura de sodiu la 100.105 degree C. Suspensia obtinuta este filtrata, spalata cu apa, uscata la 100...105 degree C si conditionate de 99,9% Bi2O3 si o granulatie de 40 miu.
