Concrete superplasticizers are basically prepared by compounding various materials such as polycarboxylate water-reducing mother liquor and polycarboxylate slump-preserving mother liquor plus retarders, air-entraining agents, and defoaming agents.…
Foam concrete blocks are made from foam that is mixed with a cement-sand mix and used as a building material. They are less expensive than conventional concrete blocks and are resistant to cracking. They are also environment-friendly. However, you sh…
Metal powder manufacturing is a basic aspect of powder metallurgy Different methods for preparing metal powders include reduction, electrolysis, carbonyl decomposition, grinding and atomization…
Amorphous boron is the nonmetallic compound of boron. It is a tasteless and odorless element that falls between the metal element series and the non-metal series. Its atomic radius is relatively small and it has a centralized nuclear charge. It has n…
Introduction to eruptive compoundsEruptive compounds, attired steels (additionally known as eruptive welding), were found by a bit of luck: in 1944, the American L.R. Carl, in an eruptive surge test, mistakenly found two thin brass sheets 1 inch in d…
Boron nitride is a chemical compound that contains equal amounts of boron and nitrogen atoms. Its empirical formula is BN, which is the same as carbon. It can take on various polymorphs, with the diamond-like polymorph being the hardest known materia…
TRUNNANO is a professional nanomaterial supplier of high purity ceramic powder, graphite powder, boron powder, Zinc sulfide (ZnS), 3D printing metal powder, and so on.…
Calcium stearate is a white powder that has a smooth feel. It is soluble in organic solvents, such as ethanol and toluene. It breaks down slowly to produce stearic acid. However, it is not gluten-free. Whether it is safe to eat is debatable.…
Silicon nitride ceramics have many advantages that metal materials and polymer materials do not have, such as high temperature resistance (bending strength above 350MPa at 1200 ℃), acid and alkali corrosion resistance, self-lubrication and so on. Sil…
Among the various applications of bismuth oxide powder are metal surface treatment products, plastics, and coating products. The powder also plays a significant role in chemical vapor deposition, thermal evaporation, and electron beam evaporation.…
Molybdenum grease is a type of lubricant that has low friction and a high pressure-absorption capacity. It also provides protection against stick-slip and anti-corrosion properties. It is used in press-fit production of all types of machine elements.…
Boron carbide is also one of the lightest ceramics available. Its properties include high hardness, low thermal conductivity, and good chemical stability.…
