Overview of boron nitride powder
Hexagonal boron nitride is used as an oil additive to enhance the anti-friction and anti-wear properties of lubricating oils and improve the friction and lubrication properties of base oils. Boron nitride has a lubricating effect. Boron nitride is relatively stable to almost all organic solvents and corrosive substances. At the same time, boron nitride is white and non-toxic.
CBN is usually black, brown or dark red crystals with a sphalerite structure and good thermal conductivity. The hardness is second only to diamond, and it is a superhard material that is often used as tool material and abrasive.
Boron nitride is chemically resistant and not attacked by inorganic acids and water. The boron-nitrogen bond is broken in hot concentrated alkali. Above 1200℃, it begins to oxidize in air. Decomposition begins at about 2700°C under vacuum. Slightly soluble in hot acid, insoluble in cold water, relative density 2.29. The compressive strength is 170MPa. The maximum operating temperature is 900 °C in an oxidizing atmosphere, and can reach 2800 °C in an inactive reducing atmosphere, but the lubricating performance is poor at room temperature. Most of the properties of boron nitride are better than carbon materials. For hexagonal boron nitride: low coefficient of friction, good high temperature stability, good thermal shock resistance, high strength, high thermal conductivity, low coefficient of expansion, high electrical resistivity, corrosion resistance, microwave or Infrared transparent.
Boron nitride material structure
Boron nitride is a hexagonal crystal, most commonly a graphite lattice, and there are also amorphous variants. In addition to the hexagonal crystal form, boron nitride has other crystal forms, including: rhombohedral boron nitride (r-BN), cubic Boron nitride (c-BN), wurtzite boron nitride (w-BN). Two-dimensional boron nitride crystals like graphene have even been found.
Application of boron nitride powder
1. Release agent for metal forming and lubricant for metal drawing.
2. High-temperature solid lubricants, extrusion anti-wear additives, additives for ceramic composite production, refractory materials and anti-oxidation additives, especially suitable for molten metal corrosion-resistant occasions, temperature-increasing additives, and high-temperature insulating materials.
3. Metallurgical continuous casting steel separation ring, amorphous iron launder, continuous casting aluminum mold release agent (various optical glass mold release agents)
4. The filler used for lipstick in cosmetics is non-toxic, lubricated and shiny.
5. It can be used as an additive for lubricating oil, because boron nitride itself has good lubricity and meets the needs of lubricating oil, and boron nitride as an additive for lubricating oil also has some other advantages.
6. Boron nitride powder has various functions and is an additive for various materials. Boron nitride is widely used in chemical, textile, aerospace and many other industries.

The day after the shooting at a Texas elementary school, the National Rifle Association issued a statement saying it "extends its deepest sympathies to the families and victims involved in this terrible and evil crime," adding it would "reflect on these events and pray for the victims."
It comes just days before the National Rifle Association's annual convention in Houston, Texas. Houston is less than five hours away. Texas Governor Tony Abbott, Senator Ted Cruz, and others are scheduled to attend the event, which has also caused a lot of controversies.
Texas Democratic gubernatorial candidate Mark O 'Rourke took to social media to call on Abbott to pull out of the convention, urging that it be held outside Texas. Many American netizens also took to social media to express their dissatisfaction. "I wish the NRA's annual meeting was held three days after 19 children and two adults were massacred," said one. "The school shooting was not a lone Wolf, but with the help of the NRA."
Between 2000 and 2020, US gun manufacturers produced more than 139 million guns for the civilian market, according to the Justice Department report. The NATIONAL Rifle Association (NRA) is one of the leading gun rights advocates with more than 5m members and deep pockets. The United States has not passed major gun control laws for more than two decades, blocked by gun interests.
