We synthesized pure polycrystalline cubic boron nitride (cBN) and wurtzite boron nitride (wBN) by the direct conversion method from hexagonal boron nitride. We measured their longitudinal-wave elastic constants CL between 20 and 300 K using picosecon...…
Titanium Aluminum Carbide MAX Phase Micron-Powder. Chemical Name: Titanium Aluminum Carbide. Titanium aluminum carbide belongs to the hexagonal crystal system and: it has the same conductivity or heat conduction as metal but has the same high elastic...…
What is Ti3AlC2?Titanium Aluminum Carbide MAX Phase Micron-Powder. Chemical Name: Titanium Aluminum Carbide. Titanium aluminum carbide belongs to the hexagonal crystal system and: it has the same conductivity or heat conduction as metal but has the s...…
Crystalline bulk silicon is relatively inert but becomes more reactive at high temperatures. Still, the formation of the vitreous dioxide rapidly increases between 950 °C and 1160 °C, and when 1400 °C is reached, atmospheric nitrogen also reacts to ...…
What is graphite?This variety of Graphite is typically formed by the metamorphism of coal beds or carbon-rich sediments associated with igneous activity. It is generally a soft, darker black-colored graphite, less reflective than other varieties of n...…
What is Titanium diboride?A hot pressing process prepared titanium diboride (TiB2) and its ceramic composites. The sintering process, phase evolution, microstructure, and mechanical properties of TiB2 ceramics prepared by using different milling medi...…
Cellulose derivatives cover the range of modified celluloses approved as food additives. These are methyl cellulose E461 (MC) and hydroxypropyl methylcellulose E464 (HPMC), used for binding and shape retention, film formation and barrier properties, ...…
What's amorphous, boron powder? Amorphous Boron's chemical properties are much more active than that of crystallized boron. The hardness of crystalline boron means that it can often be used in place of diamonds to cut tools and drill bits. To increa...…
Crystalline silica powder is the crystal form of silica. This can be made by crushing silica, and then classifying it prior to grinding. Quality: 99.8%. 600 mesh About Crystalline Silica Powder Crystalline Quartz Powder SiO2 : Silica cr...…
Can Zinc Sulfide a Crystalline Ion? In the wake of receiving my first zinc sulfur (ZnS) product I was eager to know if this was an ion that is crystallized or not. In order to determine this I conducted a variety of tests including FTIR-spectra, zinc...…
Recently, covid 19 outbreak spreads in Shanghai, China. There are more than 25,000 new asymptomatic domestic infections every day. China is implementing a dynamic zero-out policy. A leading respiratory expert said the key to COVID-19 prevention and c…
Is boron amorphous or crystalline?Boron can be prepared in several crystalline and amorphous forms. The well-known forms of crystallization are α-rhombohedral (α-R), β-rhombohedral (β-R) and β-tetragonal (β-T). In spec…
What is bismuth oxide?Bismuth oxide is a not natural substance with the molecular formula Bi2O3. The pure item has α & alpha; kind, & beta; kind, α as well as & delta; kind. & alpha; kind is yellow monoclinic crystal, family member thickn...…
The binder for silicon carbide is made from white polymer, with a mere 1% addition. It improves the hydrophilicity and has a strong bonding function with silicon carbide raw material. Quartz sand, wood chips, salt, coke and anthracite are used as raw...…
The unique challenge with titanium welding, however, is oxygen embrittlement. When the material is heated during welding, oxygen — like that found in ambient air — can infiltrate and corrupt the weld. The E6010 stick welding electrode is arguably the...…
