What is Hafnium Diboride HfB2 Powder?

Analysts at JPMorgan recommended selling or "underweight" emerging market local currency sovereign debt because of the global impact of the Ukraine-Russia crisis.

JPMorgan estimated that fixed-income assets in emerging markets have lost 6-9 percent of their value since Russia invaded Ukraine a month ago, with nervousness about the war and its impact on global energy and food prices adding to existing pressures.

Some leading emerging market central banks are signaling that interest rates now need to rise faster than previously expected, which fuels fears of "stagflation". Stagflation means when high inflation and higher interest rates undermine economic growth.  

With both the U.S. Federal Reserve and emerging market central banks raising interest rates, JPMorgan also said it made sense to "underweight" emerging market assets by taking advantage of the recent pullback in local currency bond yields relative to TREASURIES.  

JPMorgan said major metals exporters such as South Africa, Chile, and Peru could still do well, but warned that emerging market fixed income assets now faced a more "stagflationary" trajectory.

The markets and prices of many commodities, metals, chemicals like the HfB2 Powder still face uncertainty.

Introduction to Hafnium Diboride HfB2 Powder
Hafnium diboride or HfB2 belongs to ultra-high temperature ceramics and is a ceramic composed of hafnium and boron.
 
Physicochemical Properties of Hafnium Diboride HfB2 Powder
HfB2 has a melting temperature of about 3,250 °C. It is an unusual ceramic with relatively high thermal and electrical conductivity, sharing the same properties as titanium and zirconium diboride of the same structure. It is a gray metal appearance material. Hafnium diboride has a hexagonal crystal structure with a molar mass of 200.11g/mol and a density of about 10.5g/cm3.
Hafnium diboride is usually combined with carbon, boron, silicon, silicon carbide, and nickel to improve the consolidation (sintering) of hafnium diboride powders. It usually forms a solid through a process called hot pressing, in which heat and pressure are used to press the powder together.

Applications of Hafnium Diboride HfB2 Powder
Due to its strength and thermal properties, hafnium diboride has potential for use in ultra-high-speed reentry aircraft, such as heat shields for intercontinental ballistic missiles or aerodynamic fronts. Unlike polymers and composites, HfB2 forms aerodynamic shapes and does not melt during reentry.
Hafnium diboride is also being studied as a possible new material for nuclear reactor control rods. It is also being studied as a diffusion barrier for microchips. If the synthesis is correct, the barrier thickness can be less than 7 nm.
 
Related Elements
Boron (B):
Boron (atomic symbol: B, atomic number: 5) is a p-block element of group 13 of Period 2, with an atomic weight of 10.81. Each boron layer has 2,3 electrons, and its electron configuration is [He] 2s2, 2p1. The boron atom has a radius of 90pm, and the van der Waals radius is 192pm.
Boron is classified as a metal-like substance that does not naturally occur on Earth. The element boron, along with carbon and nitrogen, is one of the few elements in the periodic table known to form stable triple bond compounds. The bandgap of boron ranges from 1.50 to 1.56 eV, which is higher than that of silicon and germanium.
 
Hafnium (Hf):
Hafnium (atomic symbol Hf, atomic number 72) is an element of unit D, group 4, of Period 6, with an atomic weight of 178.49. Bohr model of hafnium the number of electrons in each layer of hafnium is 2,8,18,32,10,2 and the electron configuration is [Xe] 4f14 5d2 6s2. The hafnium atom has a radius of 159pm and the van der Waals radius is 212pm.
Hafnium was predicted by Dmitri Mendeleev in 1869, but was not isolated for the first time until 1922. In its elemental form, hafnium has a lustrous silver-gray appearance. The element hafnium does not exist in nature as a free element. It is found in zirconium compounds such as zircon. Hafnium is commonly a component of superalloys and circuits used in semiconductor device manufacturing.
