Melting point above 3000K?
Substances with melting points above 3000K are typically found in materials like refractory metals (e.g. tungsten, rhenium) and ceramics (e.g. alumina). These high melting point materials are often used in industries requiring extreme heat resistance, such as aerospace, electronics, and high-temperature applications.
How hard is hafnium?
Hafnium is a dense, ductile metal that is relatively soft compared to other metals, such as steel or titanium. It can be easily machined and formed, but it does have a high melting point and is known for its high resistance to corrosion.
Is hafnium flammable?
Not known but very probable not flammable.
Why pure substances have fixed melting points?
High melting points:Carbon (sublimes at about 4000 K)Tungsten 3683 KTantalum hafnium carbide 4488 KLow melting points:Helium (does not solidify at normal pressures)Hydrogen 13 K
What are uses for hafnium?
Hafnium is a rare element with rare applications: - component of control rods for nuclear reactors - component of some alloys - getter in lamps and tubes - electrode for plasma cutters - hafnium dioxide was recently used as an electrical insulator in microprocessors - hafnium carbide has a very great point of melting (the most refractory compound known today) - possible use in weapons (USA)

What is a solid at room temperature has a high melting point and dissolves easily in water?
Table salt (sodium chloride) fits this description. It is a solid at room temperature, has a high melting point, and dissolves easily in water due to its ionic nature, breaking down into its component ions (sodium and chloride) when in contact with water.
What is the most heat resistant element?
Hafnium carbide with the melting point of 3900 0C. For a ternary compound: tantalum hafnium carbide with the melting point of 4215 0C.

Is hafnium metal or non-metal?
Hafnium is a metal. It is a transition metal that is commonly used in the production of nuclear reactors and in semiconductor manufacturing due to its high melting point and resistance to corrosion.
Is hafnium flammable?
Not known but very probable not flammable.
Does hafnium have a high density?
The density of hafnium is 13,31 g/cm3.
Is hafnium a base?
No, hafnium is not a base. Hafnium is a chemical element with the symbol Hf and atomic number 72. It is a transition metal that is commonly used in nuclear reactors and electronic devices due to its high melting point and resistance to corrosion.

What are the chemical properties of Hafnium?
Hafnium is a transition metal that is corrosion-resistant, has a high melting point, and forms stable compounds with oxygen and nitrogen. It is also a good absorber of neutrons, making it useful in nuclear reactors.
How is hafnium used in life?
Hafnium is used for many things in the scientific and nuclear world. The most common being this:1. The most important use of hafnium is in nuclear reactors for nuclear fission experiments. Hafnium can absorb neutrons easily and effectively. Hence, it is used in these experiments.2. It is used to create The Hafnium Bomb.3. It is used in gas and incandescent lamps.
