The most important applications of ZrB2 are in the high-temperature fields where it is used as a refractory material; hence, the effect of alumina on the oxidation rate of ZrB2 ceramic should be essentially investigated…
What is Foaming agent?The foaming agent is an indispensable component in the preparation of foam concrete by using prefabricated foams. This study used four types of foaming agents to prepare foam concrete. Effect of the foaming agent on the properti...…
What is Manganese oxide?Manganese oxide minerals have been used for thousands of years—by the ancients for pigments and to clarify glass, and today as ores of Mn metal, catalysts, and battery material. More than 30 Mn oxide minerals occur in various ...…
What is Silicon nitrides?Silicon nitrides (Si3N4) feature an excellent combination of material properties. The microstructure consists of elongated crystals that interlock into micro-rods. One application where this combination of properties has prov...…
The most recently identified iron(III) oxide polymorph, ε-Fe2O3, shows the highest coercivity among all known metal oxides (20–22.5 kOe) and could be used as a magnetic recording material for high-density recording media. In addition, its magnetoelec...…
Molybdenum disulfide (MoS2) is one of the most widely used solid lubricants. Much research has been conducted on its friction properties and the reasons for its good lubricating behavior. Johnson, Winer, and Farr have written excellent reviews on the...…
Antimony-doped tin oxide (ATO) is probably the most extensively studied compound among conductive oxides. The bulk and surface chemistry of SnO2 is well-studied and has been the subject of a detailed review. Various surface additives and lattice dopa...…
Iron is a metal ion in the body that plays a critical role in various physiological functions, including DNA synthesis, mitochondrial respiration, and oxygen transport. Iron in the food sources is primarily absorbed via endocytosis—mediated by divale...…
Scientists at the Tokyo Institute of Technology have shown that copper oxide particles on the sub-nanoscale are more powerful catalysts than those on the nanoscale. These sub-nanoparticles can also catalyze the oxidation reactions of aromatic hydroca...…
What is Molybdenum disulfide?Molybdenum Disulfide is a dry/solid lubricant powder, also known as molybdenite (principal ore from which molybdenum metal is extracted), and has the chemical formula MoS2. It is insoluble in water and dilute acids. The c...…
What is graphite?Graphite is a soft, crystalline form of carbon. Other forms are diamond and fullerenes ("buckyballs"). It is gray to black, opaque, and has a metallic luster. It is flexible but not elastic. Graphite occurs naturally in metamorphic r...…
What is zirconia Zirconium Dioxide has the chemical formula ZrO2. It is zirconium's main oxide. Normal conditions result in a white, tasteless and odorless crystal. It's insoluble with water, hydrochloric or dilute sulfuric acid. Chemically, it is...…
There is also an excellent linear relationship between the consistency of cement slurry and the content of hydroxypropyl methylcellulose, and hydroxypropyl methylcellulose can significantly increase the viscosity of mortar. The more significant the r...…
In principle, any soluble copper salt could be used as a precursor to prepare CuO nanostructures without much difference, or at least there seems to be no report on the influence of copper salt precursor. Various copper salts such as chloride, nitrat...…
Calcium stearate can also be used as a flatting and waterproofing agent in coating material production. Good lubricity is widely used in paper making, applying lubricating agents and perchloroethylene heat stabilizer fields. Accompanied by the rapid ...…
