Exempel på hur man kan använda DIBORIDE i en mening

• Titanium diboride powder can be prepared by a variety of high-temperature methods, such as the direct reactions of titanium or its oxides/hydrides, with elemental boron over 1000 °C, carbothermal reduction by thermite reaction of titanium oxide and boron oxide, or hydrogen reduction of boron halides in the presence of the metal or its halides.
• Hafnium diboride is a type of ceramic composed of hafnium and boron that belongs to the class of ultra-high temperature ceramics.
• They may occur in compounds such as molybdenum boride, hafnium diboride, titanium diboride, dysprosium titanate and gadolinium titanate.
• However, unlike hexagonal boron nitride, which lacks electrons in the plane of the covalent atoms, the delocalized electrons in magnesium diboride allow it to conduct electricity similar to isoelectronic graphite.
• Rhenium diboride is occasionally, and controversially, cited as a "superhard material" due to its high hardness level.
• It is an unusual ceramic, having relatively high thermal and electrical conductivities, properties it shares with isostructural titanium diboride and hafnium diboride.
• Examples of multi-component superconductivity are multi-band superconductors magnesium diboride and oxypnictides and exotic superconductors with nontrivial Cooper-pairing.
• The powder-in-tube (PIT, or oxide powder in tube, OPIT) process is an extrusion process often used for making electrical conductors from brittle superconducting materials such as niobium–tin or magnesium diboride, and ceramic cuprate superconductors such as BSCCO.
• The main field of Naidyuk's scientific research is the study of the interaction of conduction electrons with quasiparticle excitations in solids using the method of point contact spectroscopy; research of strongly correlated electronic systems and point contact spectroscopy of topical superconductors, including promising ones such as magnesium diboride, rare-earth nickel-borocarbide compounds, newest iron-based superconductors, and topological semimetals.
• The tetraboride can be obtained by heating an oxide or halide of americium with magnesium diboride in vacuum or inert atmosphere.
