At home and abroad, the production of alumina with good particle size has become a hot issue. Different synthetic methods were used to prepare morphological aluminas powders. These included fibrous, sand and plate, rods, and porous alumina membranes....…
Abstract the amorphous boron powders with high activity were prepared by the high-energy ball milling–combustion synthesis method. The milling rate and milling time effects on the crystallinity, microscopic morphology, and reactivity of amorphous bor...…
The earliest routes to elemental boron involved the reduction of boric oxide with metals such as magnesium or aluminum. However, the product is almost always contaminated with borides of those metals.[citation needed] Pure boron can be prepared by re...…
Zirconium diboride (ZrB2) is a typical ultra-high-temperature ceramic material (UHTC). In this work, the preparation of ZrB2 by reducing zirconia (ZrO2) with calcium hexaboride (CaB6) was studied in detail. With the assistance of molten salt, the red...…
Cubic boron nitride is produced by treating hexagonal boron nitride at high pressure and temperature, much as synthetic diamond is made from graphite. Direct conversion of hexagonal boron nitride to the cubic form occurs at pressures up to 18 GPa and...…
The nitridation or ammonolysis of boron trioxide produces hexagonal boron nitride. H-BN parts can be made by hot-pressing with subsequent machining; the machining cost is low due to the mechanical hardness similar to graphite. The parts are made from...…
What is Water-based calcium stearate?Calcium stearate lubricant is a water-insoluble metallic soap class surfactant. Generally, it is made as an aqueous liquid dispersion. Water-based calcium stearate refers to water-based calcium stearate, also know...…
An important factor in concrete foam technology is temperature. First, this is the temperature of the outside air and the foam concrete mix when laying. When the temperature drops below +15° C, the time of setting of cement, the set of plastic, and f...…
What is Iron Oxide?Iron oxide, also called ferric oxide, is an inorganic compound with the chemical formula Fe2O3. It is one of the three major oxides of iron, the remaining two being iron(II) oxide (FeO), which is the rare iron (II and III) oxide (F...…
Considering the predominant applications of antimony tin oxide nanoparticles, numerous methods and techniques have been introduced to obtain them. It has to be taken into consideration that the properties of ATO are influenced by the synthesis and pr...…
What is ATO?Antimony-doped tin oxide (ATO) nanoparticles have been proven to exhibit special optical properties and excellent electrical conductivity to be used as thin film electrodes. Studies have shown that antimony-doped tin oxide possesses a hig...…
ATO-based electrodes are prepared by ultrasonication of 300 mg ATO in isopropanol and subsequent addition of PTFE binder (PTFE micro powder, 3M, USA) with a binder-to-active material ratio of 5/95. The ink is mixed in a planetary orbital mixer (Think...…
Tungsten dioxide is its name. Formula: 247.97 Molecularweights W2. Furthermore, hexagonal packaging contains 99.9% pure About Tungsten Disulfide WS2: Tungsten disulfide It is possible to find it in combination with sulfur or tungsten. T...…
What's silicon nitride? Silicon nitride This important structural ceramic material has high hardness and wear resistance. The atomic crystal resists high temperature oxidation. It can also resist cold or hot shocks. It can also be heated up to 10...…
How do you define it? Titanium Boride ? Gray or gray-black titanium boride is powder with hexagonal crystal structures. It is very hard and has a melting point of 2980degC. Titanium dioxide has an air anti-oxidation temperature at 1000°C....…
