High Purity Boron Carbide B4C Powder CAS 12069-32-8, 99%

Description of Boron Carbide Powder ：

Boron carbide is an inorganic compound that is composed of boron and carbon. Its molecular formula is B4C, where the atomic ratio of boron and carbon is 1:1, and it is a covalent compound. Boron carbide is a compound with high hardness, melting point, chemical stability, excellent thermal conductivity, and other physical and chemical properties. The crystal structure of boron carbide is a hexagonal crystal system belonging to the fiber boride family. Its appearance is a black or gray powder that is not soluble in acid or water but in alkali. Boron carbide has a density of about 2.5g/cm³, a melting point of up to 2350°C, and a high hardness, second only to diamond and cubic boron oxide, and is one of the refractory metal borides. Boron carbide has strong reducibility but will not be oxidized at room temperature. It reacts with oxygen, carbon dioxide, nitrogen, and halogens at high temperatures. Boron carbide has good thermal stability in a reducing atmosphere and can maintain its structural integrity at high temperatures.

Boron Carbide Powder Uses ：

Structural materials field 

Boron carbide has high hardness and excellent wear resistance and can be used to manufacture cutting tools, wear resistance, and high-temperature mechanical parts. Its hardness is very high, second only to diamond and cubic boron oxide, so it can replace other cutting tool materials, such as high-speed steel and carbide. At the same time, boron carbide also has good corrosion resistance and high-temperature stability. It can maintain its structural integrity at high temperatures to manufacture high-temperature furnace parts, high-temperature mechanical parts, etc. 

Ceramic additive field 

Boron carbide can improve ceramic materials' hardness and wear resistance and is used as a ceramic additive. In the ceramic industry, boron carbide can be added to alumina, silicon oxide, silicon carbide, and another ceramic matrix to improve its hardness and wear resistance and extend its service life. At the same time, boron carbide can also be used to prepare ceramic materials with high thermal conductivity and low thermal expansion coefficient, such as boron nitride and silicon carbide ceramics. 

Electronic materials field 

Boron carbide has excellent thermal conductivity and can manufacture heat-dissipation materials for high-temperature electronic devices. In power and electronic equipment, high-temperature vacuum tubes, electron beam evaporation sources, and photomultiplier tubes need heat dissipation materials, and boron carbide's high thermal conductivity can meet their requirements. At the same time, boron carbide can also be used to manufacture high-temperature structural materials such as high-temperature sensors and protective covers. 

Other fields 

Boron carbide can also be used as a catalyst, superhard material, protective coating, and other applications in different fields. In the field of catalysts, boron carbide can be used as a catalyst carrier to prepare highly active catalysts. In the field of superhard materials, boron carbide can be used to manufacture high-hardness coatings to improve the surface hardness of materials. In the field of protective coatings, boron carbide can be used to coat various substrates to improve their corrosion and wear resistance.

  
Production Method of Boron Carbide Powder ：

Hot pressing method 

Hot pressing is a commonly used method to prepare boron carbide, which synthesizes boron and carbon raw materials under high temperature and high pressure to produce boron carbide. The advantage of the hot pressing method is that high-purity boron carbide can be prepared while the reaction temperature and pressure are high, and the hardness and melting point of boron carbide can be prepared. The reaction time of the hot pressing method is longer, and it needs to go through several hot pressing and cooling processes, so the production efficiency and cost are low. 

Electric melting method 

The electrowetting method is to melt the raw materials of boron and carbon in an electric furnace at high temperatures and then react to produce boron carbide. The advantage of electrowetting is that a large amount of boron and carbon can react relatively quickly, and high-purity boron carbide can be prepared simultaneously. However, the electric melting method has a large energy consumption, requires high-purity raw materials, and requires higher equipment and operation requirements. 

Laser cladding method 

The laser cladding method uses a high-energy laser beam to react with a powder mixture of boron and carbon on the surface of the substrate to form a layer of boron-carbide coating. The advantage of the laser cladding method is that boron carbide can be coated on the surface of various materials, improve the hardness and wear resistance of the material, and can complete a large area of coating preparation in a relatively short time. However, the equipment cost of the laser cladding method is higher, and the requirements for operation technology are also higher.
