Technical Parameters of BoronCarbide Nanoparticles B4C Powder

Production Method of Boron Carbide Nanoparticles Nano-B4C Powder:

Mechanical alloying method: It is a standard method for preparing nanometer boron carbide powder. The technique is to mix boron carbide particles with metal or alloy powder and then ball milling for a specific time in a high-energy ball mill to thoroughly mix the boron carbide particles and metal or alloy powder. Finally, the nano-boron carbide powder is obtained. The advantages of mechanical alloying are a simple preparation process and low cost, but the disadvantages are low production efficiency and low powder purity.

Chemical vapor deposition: The method is to mix carbon source gas (such as CH4) and boron source gas (such as B2H6) according to a particular proportion through high-temperature heating to make it undergo a chemical reaction. The generated boron carbide particles are deposited on the cooler or sediment and finally get nano-boron carbide powder. The advantages of chemical vapor deposition are high purity, fine particle size and uniform distribution of the prepared powder, but the disadvantage is that the production cost is high.

Physical vapor deposition is a method of physically depositing carbon and boron elements into nanometer boron carbide powders. The technique is to vaporize or sputter carbon and boron elements into atomic or molecular states in gas or plasma by heating or ion beam bombardment and then deposit them into nano-boron carbide powder on the cooler or sediment. The advantages of physical vapor deposition are high purity, fine particle size and uniform distribution of the prepared powder. Still, the disadvantage is that the production cost is high, making it difficult for large-scale production.

Self-propagating high-temperature synthesis: Self-propagating high-temperature synthesis prepares nanometer boron carbide powder by high-temperature combustion reaction. The method is to mix carbon and boron elements in the form of solid or liquid through external ignition to trigger the combustion reaction; the heat generated by combustion makes the mixture temperature rise rapidly and reach the synthesis temperature of boron carbide and finally get nano-boron carbide powder. The advantages of self-propagating high-temperature synthesis are a simple preparation process and low cost. Still, the disadvantage is that impurities are easily mixed in the production process, affecting the powder's purity.
