Abstract

Ця заявка частково є продовженням заявки з порядковим номером 462806 від 10 січня 1990 р. Спосіб отримання танталового порошку включає виготовлення танталового порошку та деформування порошку до надання часткам форми пластівців, причому пластівчасті частки піддають здрібнюванню без істотного загострення периферійних країв до середнього розміру часток від 2 до приблизно 55 мкм і з площею поверхні по БЕТ приблизно від 0,5 до 5,0 м2/м, та здійснюють вибір часток із середнім розміром іі площею поверхні по БЕТ, що характеризуються відношенням розмірів (D/T) приблизно від 2 до 50.
