b4c Boron carbide ceramicPosted by googlerank faster on March 11th, 2021 b4c Boron Carbide Nozzle Boron carbide nozzle has the characteristics of high wear resistance and high hardness,high compressive strength, strong impact resistance,does not react with acid and alkali.Sintered by pure boron carbide powder,improves sandblasting efficiency, and sandblasting jet is stable,service life is very very long,wear resistance life of boron carbide nozzle is 5-10 times longer than that of tungsten steel.The boron carbide nozzle is gradually replacing the cemented carbide (tungsten steel) and silicon carbide, silicon nitride, alumina, zirconia and other materials. We can supply series of boron carbide ceramic nozzle for sandblasting,such as Boron carbide straight bore nozzle,straight bore nozzle with screw thread,venture nozzle with screw thread, lead-in nozzle and so on.Also we can make boron carbide nozzles according to your design. Boron Carbide Ring Boron Carbide Ring has a wide application scop and high interchargeability. It is compact in structure. The drive collar is clamped by the drive lug to prevent the spring from dropping. It is reliable in performance and widely used in petrochemical pumps. B4C bullet proof ceramic B4C Ceramic bullet proof plate is widely used in heavy armored protection in planes/tanks/ships, and high-class physical protection High Hardness is about HV3300,low density is about 2.5g/cm3 B4C Ceramic Liner Just send us your drawing.We make for you. The boron carbide ceramic lining also can be according to your tolerance,flatness and so on Boron carbide ceramic is one kind of technical ceramic,also can be called advance ceramic and engineering ceramic.We are professional for providing boron carbide ceramic solutions for you in shanghai in china. We are professional for providing boron carbide ceramic solutions in shanghai in china. Boron carbide commonly known as man-made diamond, is a kind of very high hardness boride.Boron Carbide Ceramics is very light technical ceramic material (about 2.5 g/cm3) as well as the hardest (be next only to diamond).Boron carbide is more stiffer and more hard than silicon carbide or tungsten carbide Boron carbide, B4C, is one of the hardest materials in the world, ranking third behind diamond and cubic boron nitride, and it is the hardest material produced in tonnage quantities. Discovered as a byproduct in the production of metal borides during the 19th century, it is produced by reacting carbon with B2O3 in an electric arc furnace through carbo-thermal reduction or gas phase reactions. Boron carbide must be milled and purified to remove metal impurities prior to commercial use. Boron carbide, the molecular formula B4C, usually of black powder. Commonly known as man-made diamond, is a kind of very high hardness boride. And acid, alkali solution can not react, easy to manufacture and relatively cheap price. Widely used in hard material grinding, grinding, drilling and other.Mohs hardness is 9.3. It is widely used in ballistic armor systems, Nozzles,Seal ring, Shaft sleeve, Nuclear Industry Materials,Grinding Materials,wear resistant lining and so on.Also we can make according to your requirement. Indicators for boron carbide ceramic Density≥2.48g/cm³ Mico Hardness≥3500(kgf/mm2) Bending Strength≥400(Mpa) Melting Point 2450℃ Operating environment High temperature,high grinding,high pressure,strong acid and alkali boron carbide Boron Carbide Machining & Grinding Boron Carbide can be machined in green, biscuit, or fully dense states. While in the green or biscuit form it can be machined relatively easily into complex geometries. However, the sintering process that is required to fully densify the material causes the Boron Carbide body to shrink approximately 20%. This shrinkage means that it is impossible to hold very tight tolerances when machining Boron Carbide pre-sintering. In order to achieve very tight tolerances, fully sintered material must be machined/ground with diamond tools. In this process a very precise diamond coated tool/wheel is used to abrade away the material until the desired form is created. Due to the inherit hardness of the material, this can be a time consuming and costly process. Boron Carbide Applications Abrasives Due to its high hardness, Boron Carbide Powder is used as an abrasive in polishing and lapping applications also as a loose abrasive in cutting applications such as water jet cutting. It can also be used for dressing diamond tools. Nozzles The extreme hardness of Boron Carbide (B4C) gives it excellent wear and abrasion resistance and as a consequence it finds application as nozzles for slurry pumping, grit blasting and in water jet cutters. Nuclear Applications Its ability to absorb neutrons without forming lived radio-nuclides make the material attractive as an absorbent for neutron radiation arising in nuclear power plants. Because of its B10 isotope Boron Carbide applications include shielding and control rod and shut down pellets. Ballistic Armour Boron Carbide (B4C) in conjuction with other materials also find use as ballistic armour for personal and military use, the combination of high harness, elastic modulus and low density give the material an exceptionally high specific stopping power to protect high velocity projectiles. Combustion in Solid Fuel Ramjets boron carbide ceramic The effect of bypass air momentum on the combustion efficiency of a Boron Carbide fueled solid fuel ramjet has been investigated theoretically. A 3D model of the flow in the aft-burner has been developed and solve numerically. The theoretical results indicate that combustion efficiency can be increased by employing bypass air with low dump momentum, in agreement with experimental results. High bypass air dump momentum was shown to enhance extinguishing of particle combustion through increased collisions with the motor walls. Other Applications Boron Carbide evaporation boats for material testing mortars and pestles, ceramic tooling dies, precision toll part. Visit our website for more Like it? Share it!
