What is Silicon nitride?The basis of silicon nitride ceramics is silicon extracted from pure quartz sand (SiO2). Silicon nitride is then usually formed through a reaction of pure silicon with nitrogen at around 1,200 °C / 2,192 °F. Ceramic components...…
The striking blend of oxidation resistance and high-temperature elasticity makes MoSi2 a promising material for high-temperature applications, such as gas turbine engines. Many researchers have strived to enhance the high-temperature creep resistance...…
About 95% of the commercial use of silicon dioxide (sand) occurs in the construction industry, e.g., for the production of concrete (Portland cement concrete). Certain deposits of silica sand, with desirable particle size and shape and desirable clay...…
Surface area measurements are performed on a gas sorption analyzer (Autosorb-iQ, Quantachrome, USA) at 77 K using nitrogen as an adsorbent. Samples are pretreated under a vacuum at 140°C for 15 h (as-synthesized ATO) or 350°C for three h (calcined AT...…
What is Calcium hexaboride?Calcium hexaboride (CaB6) is a compound of calcium and boron in which the coordination number of the calcium is 18. Calcium hexaboride is also referred to as calcium boride. It is an important material due to its large elec...…
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...…
Colloidal gold, also known as gold sol, is a suspension of gold particles formed after the gold salt is reduced to the original gold.…
Titanium nitride is a structural material with attractive golden yellow color, high melting point, high hardness, excellent chemical stability, and low wetting with metals, and has high electrical conductivity and superconductivity.…
Molybdenum disilicide is a silicon compound of molybdenum, also known as molybdenum silicide, with a molecular formula of MoSi2 and a molecular weight of 154.13. It is a gray metallic solid. Since the radii of the two kinds of atoms are not much diff...…

Among many compounds, metal borides have better high-temperature performance than metal carbides. For example, diboride (TiB2) cermet products are more suitable for use than titanium carbide (TiC) and tungsten carbide (WC) cermet products. Use under…
Titanium nitride is a compound with a molecular formula of TiN and a molecular weight of 61.88. The tiN powder is generally yellowish-brown, the ultrafine TiN powder is black, and TiN crystals are golden yellow.…
What is graphite?Graphite is minimally toxic when swallowed or used to draw on the skin. Pencils do not contain metal lead at all. If a pencil tip breaks or punctures the skin, call IPC at 1-800-222-1222 or the child's pediatrician for medical advice...…
A new high-performance, slump-retaining polycarboxylate superplasticizer has been developed. It contains isopentenyl and free radical polymerization. This is the Polycarboxylate superplasticizer for high-slump retention type TR-JS28 A high slump r...…
What is Quartz powder?Quartz powder may be used as a filler in manufacturing rubber, paint, and putty. Screened and washed, fastidiously sized quartz grains are used as filter media and roofing granules. Quartz Powder is used for traction in the rail...…
