Tungsten is one of the hardest metals in nature. It can be used in armor-piercing bullets, rocket engine nozzles and drill bits that can cut through concrete. This strength comes from the fact that tungsten has the highest melting point of any metal. But, while tungsten is very hard, it is not strong on its …
Potassium sulfide is a white, crystalline compound that has several uses across industries such as mining and oil refining. The chemical is also a common ingredient in fertilizers and a drying agent, as well as in some photographic processes. Because of its corrosive nature, proper storage and handling regulations must be followed when using potassium …
Graphite can be as hard and durable as diamond. However, its unique structure means that it is soft, light, and heat-resistant. It’s one of the most popular non-metallic minerals. It was once called Plumbago. It’s a semi-metal and crystal form carbon. Graphite is the stablest form of carbon under normal conditions. This is why graphite …
Nano silicon’s main characteristics Si Pulver The variable current laser-ion beam gasphase method is used for the preparation of nanosilicon powder. High purity, good dispersion, small particle size and uniform distribution are some of the attributes. The nanosilicon powder can also be combined with carbon nanotubes and graphite. Nano silicon carbon anode materials for lithium-ion …
Graphite dust can either be classified as natural or artificial graphite. They have the same structures as each other and share similar chemical and physical properties. However, they are used for different purposes. Researchers have mistakenly called graphite, despite the fact that they are similar in structure and chemical properties. Confusion of these two elements …
high purity graphite powder is used for the manufacture of crucibles, lubricants, stove polish, “lead” pencils, electrodes, brake linings, batteries, glass manufacturing, conductive coatings and for foundry facings. It is also used in the synthesis of single sheet graphene nanoflakes and graphite based magnetorheological elastomers.Graphite powder is produced by processing selected natural graphite with a …
What is boron caride? Boron carbide is a part of the trigonal crystal system. Unit cell contains 12 B and 3 C elements. C atoms within a unit cell are connected in a stereo diagonal arrangement. This configuration can be changed by B atoms. B4C’s molecular weight is 52.25, B21.74% and B78.25%. It can be …
What is Zirconia Toughened Alumina? Zirconia’s toughening has made Alumina more resistant to abrasion. comprises zirconia and alu. Because of its strength, zirconia is an oxide zircon. A zirconia hardened Alumina has an average zirconia:lumina ratio of 1-10 to 1. The ratio can be adjusted to fit the product. ZTA ceramics provide the best balance …
