Abstract
Invenţia se referă la domeniul tehnologiei materialelor pentru ingineria electronică, în special la domeniul preparării materialelor sub formă de monocristale şi poate fi utilizată la producerea monocristalelor de arseniură de niobiu sau tantal.Procedeul de obţinere a monocristalelor de arseniură de tantal sau niobiu prin metoda reacţiei chimice de transport într-un volum închis cu un gradient de temperatură şi folosind iodul ca agent de transport, în care bucăţi de folii de tantal sau niobiu, arsen şi iod se încarcă în fiole şi se plasează într-un cuptor cu trei zone de temperaturi de 610 °C, 850 °C şi 800 °C, zona cu temperatura de 850 °C fiind la mijlocul fiolei, arsenul - în zona cu temperatura de 610 °C, tantalul sau niobiul - în zona cu temperatura de 800 °C, iar cantitatea de agent de transport (iod) se alege în dependenţă de limitele de presiune pentru fiola aleasă pentru sinteză.
