Fracture behaviour of tungsten–vanadium and tungsten

Jun 30, 2011For the tungsten–tantalum composite material, the internal size of the "phase microstructure" is on the order of several micrometres up to several tens of micrometres (Fig. 10, Fig. 7f), so we assume that the crack is triggered within the large and linked-up tungsten regions. This is confirmed by the fact that there is a coincidence in Get price

Economic Geology of Niobium and Tantalum

Tantalum ore has characteristically grades of about 0.03% Ta 2 O 5, generally as a co-product of cassiterite and other minerals. Note that because of facile overgrinding, metallurgical recovery of columbite by crushing and milling hard-rock ore is often as low as 50%. Tantalum is silvery grey, heavy and very hard but malleable and ductile. Get price
