Boron carbide, also known as black diamond, is an inorganic substance with a chemical formula of B4C, usually a gray-black micropowder. It is one of the three hardest known materials (after diamond and cubic boron nitride) and is used in tank armor, body armor and many industrial applications. Several preparation methods of nano-boron carbide (supply 100-200nm): 1. Carbothermal reduction method Be...

Measuring the thickness of the coating layer in nanoparticles requires the use of advanced instruments and techniques. The following are possible measurement methods: Transmission Electron Microscope (TEM): This is a microscope that utilizes high-density electron beams to observe and measure the structure and properties of nanoparticles. For the measurement of the thickness of the coating layer, T...

In recent years, there has been a trend of oil-based lubricants being replaced by water-based lubricants. Boron nitride coatings are often used in forging nickel based alloys, high melting point alloys, and titanium machined parts, which not only provide lubrication but also prevent workpiece oxidation. Characteristics that forging lubricants should possess 1. Evenly moisten the surface to prevent...

What is boron carbide powder? Nano boron carbide and ultrafine boron carbide powder were prepared by variable current laser ion vapor phase method. Boron carbide, also known as black diamond, has a molecular formula of B4C and is usually a gray black micro powder. It is one of the three hardest materials known (the other two being diamond and cubic boron nitride). Hard black glossy crystal. The ha...
