3.1 Influence of K value on impurity contents of hafnium crystal bar. As shown in Table 2, compared with the sponge hafnium, all the three kinds of the hafnium crystal bars with different K values receive very good purification effect. The impurity contents of Fe, Ni, and Cr obviously decrease, and the other metal impurities are not introduced in the …

Hafnium produces a protective film of oxide or nitride upon contact with air and thus has high corrosion resistance. Hafnium is fairly resistant to acids and is best dissolved in hydrofluoric acid, in which procedure the …
As powdered hafnium can spontaneously ignite when exposed to air (pyrophoric). Isotopes of Hafnium. Hafnium has 34 isotopes, with mass number ranging from 153 to 186 [3]. There are five stable isotopes of hafnium, hafnium-176 to 180. The most stable radioactive isotope is hafnium-174, that has a half-life of 10 15 years [4]. REFERENCES [1].
So far, demonstrations of gradual/interfacial RS in amorphous hafnium oxide required an additional layer in the oxide stack such as substoichiometric AlO x (), TiO x (), or WO x (), and/or data on endurance and/or retention were missing or not reported in detail (12, 13, 15).In addition, even if the observed RS is gradual, often it is not entirely clear …

The electrode generates the plasma arc. The tip of the mild steel electrode is filled with a certain amount of hafnium. As the electrode wears this hafnium is depleted and you will see the crater in the tip of the electrode becoming bigger. The bigger it gets the more worn out the electrode becomes and a replacement might be needed.
