Product performance and application of boron nitride BN powder

 Overview of Boron Nitride BN Powder

Boron Nitride BN powder is a pure white ceramic material with a hexagonal crystal structure similar to graphite. Boron Nitride can withstand temperatures in excess of 2,000°C and, depending on the grade, has a dielectric strength of nearly 1000 volts/mil. Boron Nitride is hot-pressed in billet form and can be easily machined into bars, rods, sheets, and even custom shapes.

Product performance and application of boron nitride BN powder

Boron nitride BN is one of the simplest new polymer materials, and there are two types of hexagonal crystal and cubic crystal. 

It is a product with high temperature resistance, corrosion resistance, high insulation and good lubricity.

Its anti-oxidation temperature can reach 1000 ℃, and it also has good lubricity at high temperature. It is a good high-temperature solid lubricant.

Application of Boron Nitride BN Powder

Hexagonal boron nitride is white (clean appearance), non-toxic, and non-conductive. Excellent substitute for other commonly used lubricants in metalworking such as graphite, molybdenum disulfide, organic waxes and oils. In most cases, boron nitride can greatly improve the efficiency of these applications.

In optical applications, c-BN films are suitable as surface coatings for some optical components due to their high hardness and high transmittance in the entire wavelength range from ultraviolet (about 200 nm) to far-infrared, especially for zinc selenide (ZnSe) , Zinc sulfide (ZnS) and other window materials coating. In addition, it also has good thermal shock resistance and hardness, and is expected to be an ideal window material for high-power lasers and laser detectors.

Lithium nitride is the only stable alkali metal nitride

  Overview of Lithium Nitride  Li3N  Powder Lithium nitride is a metallic nitrogen compound with the molecular formula Li3N. It is the only stable alkali metal nitride. It is a purple or red crystalline solid, with a high melting point and a light green luster in reflected light and ruby color in transmitted light. Exposure to the air over a long period of time will eventually result in lithium carbonate. The chemistry of basic metal nitrides is extremely limited, and only lithium nitride is stable and easily prepared among binary compounds (sodium nitrite and potassium nitrite are prepared only under more extreme conditions). Lithium nitride belongs to the hexagonal crystal system. There are lithium and nitrogen layers composed of lithium and nitrogen atoms in lithium nitride crystal. The lithium atoms are arranged like carbon atoms in a graphite crystal, with nitrogen atoms at the center of a hexagon of lithium atoms. There is a lithium layer between the lithium and ni...

  Overview of Cuprous oxide  Cu2O  Powder Cuprous oxide,   the chemical formula is Cu2O, is monovalent copper oxide, a bright red powder solid, almost insoluble in water, in acidic solution disproportionation into copper and copper elemental, in the wet air gradually oxidized into black copper oxide. Cuprous oxide is mainly used in the manufacture of ship bottom antifouling paint(used to kill lower Marine animals), insecticides, and various copper salts, analytical reagents, red glass, but also used in the preparation of copper plating and copper plating alloy solution. Copper(I)oxide is also known as an inorganic compound of copper oxide with the chemical formula Cu2O. It's essentially covalent. The copper(I)oxide crystallizes in a cubic structure. When heated, hydrogen tends to reduce the disproportionation it undergoes in acidic solutions that produce copper (II) ions and copper. When the copper oxide is gently heated with metal copper, it is converted to cuprous ...

  Overview of Tungsten Disulfide Tungsten disulfide  as a potential battery material is also expected to benefit from more market replenishment. Tungsten disulfide is a layered material with remarkable surface effects, electron mobility, thermochemical stability and high electron density of states. It has been widely used for lithium and sodium storage. For example, nanocomposites as conductive additives or graphene composites as battery cathode materials can exhibit higher specific capacity and discharge efficiency, making up for the deficiencies of single-component WS2 or C as anode materials. The advent of sodium batteries is expected to alleviate the current shortage of lithium resources on the rapid development of the new energy industry, and will further stimulate the application of transition metal dichalcogenides such as tungsten disulfide WS2 in the field of power storage.  Lithium-ion batteries are a key raw material for developing energy devices and realizing t...
