When we eat nitrates, they are converted into nitrites in our digestive system, which are then converted to ammonia and disposed of by the body. Nitrites are also inorganic compounds made up of nitrogen and oxygen, but instead of three oxygen molecules they have two, NO2. Nitrates are not generally harmful unless they are consumed in massive quantities. Nitrites, on their own and in moderation, are also generally not harmful.
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.
