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.
The high melting point and oxidation resistance lead to the use of the metal in the production of vacuum furnace parts. Tantalum is extremely inert and is therefore formed into a variety of corrosion resistant parts, such as thermowells, valve bodies, and tantalum fasteners.antalum is also used for medical implants and bone repair. Its main use today is in tantalum capacitors in electronic equipment such as mobile phones, DVD players, video game systems and computers.
