Boron carbide is used extensively in refractories as well engineering ceramics, nuclear industry, aerospace and other fields due to its high melting and hardness. 1. The crystal structure and properties of boron carbonide Complex crystal structure of Boron Carbide with typical Icosahedral Boride. The stoichiometric ratio is B4C. B4C and Boron carbide have many isomers. …
Two types of zinc sulfuride exist. Zinc sulfurate is more melting than zinc sulfide. Zinc sulfide has different properties, so they can also be used in different ways. What exactly is Zinc Sulfide, and how can it help you? Zinc sulfide can be described as a mix of sulfur and zinc. The reaction of zinc …
Spherical Aluminum Oxide is one of many thermal conductive substances. Spherical HTML2O3 Materials Many crystal types and the unique chemical and physical property of alumina (and its hydrate) make them widely useful in various fields such as electronics, petrochemicals industry, refractories ceramics, papermaking pharmaceuticals and aerospace. It is closely tied to the shape and size …
Potassium Octadecanoate, also called potassium stearate, is another name. It is a white, crystalline powder. The powder is insoluble when heated water is used. The aqueous solution has a strong alkalinity to litmus (phenolphthalein) and the ethanol solution has a slightly acidic pH. The reaction of potassium hydroxide and stearic acid can neutralize it. These …

Molybdenum disulfide, which is composed of the two elements molybdenum & sulfur, has the chemical form MoS2. This compound can be classified as a transitional metal dichalcogenide. The silver-black color of the compound gives it a silvery-black appearance and its natural form is molybdenite. Most molybdenum-containing ores are made from molybdenite. The molybdenum-disulfide crystals typically …
In the beginning of 20th century, the first study to focus on self-assembly nanoparticles at interfacings was done. Pickering Emulsion is an example of a phenomenon where solid particles can spontaneously migrate onto fluid interfaces forming monolayers or multiple layers. Food, cosmetics and the pharmaceutical industry are all interested in using interfaces to aid the …
Silicon Nitride Powder Property A covalent bond compound consisting of silicon nitride and nitrogen (Si3N4). It was found in 1857. Silicon nitride is used extensively in aviation, military and other mechanical applications. Preparation Evaluation of Silicon Nitride Ceramics Silicon nitride is first prepared by obtaining silicon nutride powder. Once the powder has been obtained, then …
First, let’s talk about lubricating. These grease-based oils play an important part in machinery and equipment operation. Technology has brought about unique changes in the manufacturing industry, as well as aerospace and defense technology. The requirements of lubricants are more complex (high, low, fast, high velocity, heavy load or vacuum corrosion), ). With the advancement …
According to zhaomeng, China’s deputy secretary general of the China international graphene industries resources alliance (China IGRTA), the graphene industry is “hot”, but not enough to bring down the fever. Graphene is an alotrope of carbon. It’s a one-layer of atoms that forms each vertex in a 2-dimensional hexagonal lattice. This is the primary structural …
