Hafnium is a derivative of nuclear-grade zirconium production, widely used as an alloy in high-tech applications to improve advanced mechanical performance, especially at high temperatures. Hafnium's high melting point and corrosion resistance are critical for high-temperature applications in the aerospace and defense industries.
HAFNIUM is a likely state-sponsored cyber espionage group operating out of China that has been active since at least January 2021. HAFNIUM primarily targets entities in the US across a number of industry sectors, including infectious disease researchers, law firms, higher education institutions, defense contractors, policy think tanks, and NGOs.
Hafnium is a fascinating element, notable for its strong resemblance to zirconium, with which it is often found with in nature. This metallic element, symbolized as Hf on the periodic table, has several important industrial applications due to its unique chemical and physical properties. In this article, we will explore three major compounds of hafnium: Hafnium (IV) …
In previous studies on RT, hafnium has proven as a potential biomaterial [23,26, 36]. Functionalized hafnium oxide nanoparticles (NBTXR3) have been synthesized to increase the effects of RT . Hafnium-based nanoparticles are potent contrast enhancement agents for imaging in cancer. They are also used for liquid biopsy in diagnosing cancer . In ...
Hafnium metallurgy is a metallurgical technology for extracting the metal hafnium from hafnium-bearing minerals. In 1923, German D Koster and Hungarians pointed out that there was a new element in the X ray spectrum of several zirconium concentrates, and named it hafnium as the Latin name Hafnia of Copenhagen where it was found. ...
Hafnium is primarily utilized in the production of control rods for nuclear reactors due to its exceptional neutron absorption capabilities. Additionally, hafnium plays a crucial role in the manufacturing of high-temperature alloys and serves as a key component in the production of microchips for electronic devices. Is hafnium a rare element?
The process of obtaining hafnium diboride via the carbothermal reduction of hafnium oxide, which involves heat treatment in a vacuum furnace and a spark plasma sintering unit, was studied. When the charge was heat treated in a vacuum furnace, hafnium diboride powder characterized by the presence of secondary crystalline phases was obtained within a …
