Sweet Stocking stuffer, Christmas gift Great chemistry gift Amazing science gift The Facts Hafnium (atomic number 72) this sample is ideal for element collectors on the cheap or those conducting experiments. Hafnium is a silvery-grey metallic element. Hafnium is resistant to concentrated alkalis, but at elevated temperatures reacts with oxygen, nitrogen, carbon, boron, sulfur, and silicon. Halogens react directly to form tetrahalides. The element has superior absorption cross section for thermal neutrons excellent mechanical properties and is extremely corrosion-resistant, making hafnium conducive to producing reactor control rods in nuclear submarines. Hafnium is used in gas-filled and incandescent lamps. Zirconium and hafnium are two of the most difficult elements to separate. Hafnium is also used in photographic flash bulbs, light bulb filaments, and in electronic equipment as cathodes and capacitors. Hafnium alloys with several other metals, such as iron, niobium, tantalum and titanium. Hafnium-niobium alloys, for example, are heat resistant and are used in aerospace applications, such as space rocket engines. This is high quality yet cheap affordable hafnium Safety / Caution Keep out of reach from children! Do not breath in the metal dust. Metallic Hafnium dust could catch fire and or explode when ignited. As with most metals, So keep away from ignition sources. When working with Hafnium it is a good idea to always have some type of eye protection, mouth protection and gloves on.
