FAQ：

Q1:

What is the chemical formula for hafnium? 

The formula for hafnium is Hf. It is a metallic element with an atomic number of 72 and an atomic weight of 178.49. Hafnium has a high melting point and is a shiny silver-gray transition metal that does not interact with dilute hydrochloric acid, dilute sulfuric acid, and strong alkali solutions but is soluble in hydrofluoric acid and aqua regia. Hafnium has six naturally stable isotopes that can be used as cathodes for X-ray tubes. Aloys of hafnium, tungsten, or molybdenum can be used as electrodes for high-voltage discharge tubes.

Q2：

Physical properties of hafnium

Hafnium is a silver-gray transition metal that is malleable, easy to work and resistant to high temperatures.

It has a very high melting point of 2227°C and a boiling point of 4603°C.

The density of hafnium is 13.31g/cm³, the specific heat is 0.14J/gK, the heat of evaporation is 575KJ/mol, the heat of melting is 24.06KJ/mol, the thermal conductivity is 0.23W/cm, and the electrical conductivity is 0.0312×10^6/cm.

Q3：

Chemical properties of hafnium:

Hafnium does not react easily with water, dilute acids, or strong bases but is readily dissolved in aqua regia and hydrofluoric acid.

Hafnium is often +4 valence in compounds, and the main compound is hafnium oxide HfO2. Hafnium oxide comes in three variants: monoclinic, tetragonal, and cubic.

Hafnium can also form complexes with fluoride, such as K2HfF6, K3HfF7, (NH4)2HfF6, (NH4)3HfF7, etc.

Hafnium has good corrosion resistance and is not attacked by dilute hydrochloric acid, sulfuric acid, and strong alkali solutions.

Hafnium can be combined with oxygen, nitrogen, and other gases at high temperatures to form oxides and nitrides. At temperatures above 800°C, hafnium is rapidly oxidized to form HfO2.

Q4：

What is the difference between hafnium and hafnium powder? 

State and form: Hafnium is a metallic element. Its common form is block or sheet. Hafnium powder, on the other hand, is a metal powder made of hafnium and has the characteristics of a powder, such as fine or small particles.

Uses: Hafnium is mainly used to manufacture specific alloys and as a cathode for X-ray tubes. Hafnium powder has a wider range of uses, including control rods for atomic reactors, degassing agents, additives for cemented carbide, ignition agents, and catalysts.

Safety: Hafnium metal is relatively stable, but hafnium powder may react more easily with oxygen or other substances in the air due to its large surface area and high reactivity, thus increasing safety risks.
