Reactive sputtering of Ta with an Ar+N 2 gas mixture generates various phases such as Ta 3 N 4, Ta 3 N 5, Ta 4 N 5, Ta 5 N 6, TaN, TaN 0.43 and Ta 2 N, which have different electrical resistivity [186,187].Variation in chamber setup (e.g., with/without shield, target-to-substrate spacing, ionization) and nitrogen flow rate produces very different TaN resistivity values [186].

The Swedish chemist, Anders Gustav Ekebereg, discovered Tantalum in 1802. 11 Tantalum, in the early years of discovery, was found in its oxide form—as columbium, which is a combination of columbite and tantalite. 12 William Hyde Wollaston, an English chemist, showed that both columbite and tantalite are derivatives of the same element and ...

The price of the tantalite is very much dependent on the demand as well. The price of tantalite ore rose from about $75 per kilo in 2010 to more than $270 per kilo on 2011 and 2012. But the price has dropped since then. However, some experts point to expected growth in the electronics, aerospace, and power industry to boost the price back up.

TISSUE PROCESSING: 1. DEFINITION : Tissue processing: The aim of tissue processing is to embed the tissue in a solid medium firm enough to support the tissue and give it sufficient rigidity to enable thin sections to be cut, and yet soft enough not to damage the knife or tissue. Tissue processing stages involve: 1.1.
