Abstract

Invenţia se referă la procedee de obţinere a cristalelor ultrapure de oxid de fier (α-Fe2O3) de dimensiuni micronice şi submicronice cu utilizarea plantelor vii în calitate de transportor şi de depou al soluţiei iniţiale pentru sinteza oxidului şi poate fi aplicată la producerea cristalelor ultrapure de oxid de fier pentru biomedicină - în calitate de material de contrast organotrop pentru rezonanţă magnetică, în electrotehnică pentru înregistrări magnetice, în calitate de termometre magnetice datorită proprietăţilor paramagnetice în câmp magnetic slab, în calitate de catalizatori în compuşi pirotehnici, şi pigmenţi minerali în diferite domenii ale industriei etc.Scopul prezentei invenţii este crearea unui procedeu care cere puţine cheltuieli de obţinere a cristalelor ultrapure de oxid de fier (α-Fe2O3) de dimensiuni micronice şi submicronice.Procedeul include menţinerea lujerilor plantelor vii în soluţie concentrată de clorură de fier timp de 2…3 zile la temperatura camerei, încălzirea lor până la temperatura coacerii în fiolă deschisă timp de 8…10 ore, coacerea la temperatura de 600…650°C timp de 2…3 ore şi răcirea lentă până la temperatura camerei în regim de etuvă deconectată.Rezultatul tehnic constă în obţinerea cristalelor ultrapure de oxid de fier (α-Fe2O3) de dimensiuni micronice şi submicronice datorită utilizării celulelor de plante vii în calitate de transportor şi depou al soluţiei iniţiale pentru sinteza compusului.
