niobium
Niobium is a transition metal element. Niobium is a lustrous gray
metal. High purity niobium metal has high ductility, but will
harden with the increase of impurity content. Niobium has a very
low cross-section for thermal neutrons and is therefore of
considerable use in the nuclear industry. Niobium is a metallic
element. Niobium is a gray metal, melting point 2468℃, boiling
point 4742℃, density 8.57g/cm3. Niobium is a lustrous gray metal
with para magnetism. High purity niobium metal has high ductility,
but hardens with increasing impurity content. Its outermost shell
configuration is very different from that of the other five.
Niobium has the highest critical temperature. Alloys made of
niobium, with critical temperatures as high as 18.5 to 21 degrees
absolute, are the most important superconducting materials
available. Niobium on surgical medical also occupies an important
position, it not only can be used to make medical apparatus and
instruments, and it is very good "biological adaptability
material", because it has excellent corrosion resistance, not with
all kinds of liquid substances in the body, and almost no damage to
biological tissue, for any sterilization method can adapt to, So it
can bind to organic tissue for a long time and remain harmlessly in
the body.
Niobium can also induce precipitation and control the cooling rate to realize the dispersion of precipitates. Adjust the toughness level of steel in a wide range. Therefore, the addition of niobium can not only improve the strength of steel, but also improve the toughness, high temperature oxidation resistance and corrosion resistance of steel! The brittle transition temperature of steel is reduced to obtain good welding and forming properties.
