You might be confused to see Cafe 125 listed on your W-2 form. This may sound like it has something to do with where you go on your lunch break, but there is a more reasonable explanation. Cafe 125 stands for IRS regulation code section 125 regarding tax-free cafeteria plans.
The tantalum nitride films consist of a mixture of metallic tantalum, Î²-TaN 0.05, Î³-Ta 2 N and cubic/hexagonal TaN phases, their composition depending on both the ion dose and ion energy. 13. The kinetics of nitridation is characterised by two stages.
Tantalum is a rare, hard, blue-gray, lustrous transition metal that is highly corrosion-resistant. It is part of the refractory metals group, which are widely used as minor components in alloys.The chemical inertness of tantalum makes it a valuable substance for laboratory equipment and a substitute for platinum.ts main use today is in tantalum capacitors in electronic equipment such as mobile phones, DVD players, video game systems and computers. Tantalum, always together with the chemically similar niobium, occurs in the minerals tantalite, columbite and coltan (a mix of columbite and tantalite).
