Nano B4c Powder 0.5um Boron Carbide Nano Powder Particles 500 Boron Carbide for Ceramic¹

Product Description Product DescriptionBoron Carbide Powder (B4C) a black crystal powder, is one of the hardest Man-Made materials. Its hardness with Mohs hardness 9.36 and microscopic hardness 5400-6300kg/mm2 is only near upon diamond. Its density is 2.52g/cm3 and melting point is 2450oC. It has excellent abrasion resistance and large neutron-absorbing cross section. The boron carbide possesses properties of endurance hi/low temperature, no reaction with either acids or alkalis, high grinding efficiency, no magnetism. It is a good replacement of diamond. Boron carbide also possesses the special properties of light quality, neutron absorbing, semi-conductivity, etc., so it is widely used in machinery, electronics, instrumentation, metallurgy, national defense, nuclear, aviation industry, and also used as abrasives, classic refractory and specific welding materials, human protection materials and so on. Boron carbide is widely applied as follows: boriding refractory, ion transfusion, film layer as well as grinding, polishing, lapping, drilling hard metal alloys, sapphire, watches, jewels, etc. Meanwhile, it is main material for the wear-resisting parts, precise meter-age element, sandblasting nozzle, precise spray nozzle, sealed washer, smelting boron steel, boron alloy, etc. Boron carbide has showed many better properties of physics and chemistry in the hi-science/technology fields.Detailed Photos SpecificationPhysical CharacteristicsItemCrystal systemCrystal colorDensityMelting pointMohs hardnessMicro hardnessBoron carbideHexagonalBlack2.52g/cm32450oC9.365400-6300kg/mm2 Chemical CompositionGrain sizesChemical composition(%,by weight)B4CT.BF.BT.CF.CFe2O3F4-F90≥95≥76≤0.318-21≤1.5≤0.3F100-F220≥96.5≥76≤0.318-21≤1.6≤0.3F230-F320≥9677-81≤0.418-21≤1.5≤0.2F360-F500≥9576.5-80≤0.418-21≤1.8≤0.2F600-F800≥9476-80≤0.4518-21≤2.0≤0.25F1000-F1200≥93.576-79≤0.518-21≤2.5≤0.3 Company ProfileHebei Baotong New Materials Co., Ltd. is a collection of production, processing, sales in one of the silicon carbide boron carbide enterprise. It has 26000KVA, 12500KVA black silicon carbide smelting production lines, and multiple boron carbide smelting furnaces. And equipped with segmented sand, fine powder processing equipment, can be customized according to customer requirements. Processing granularity. In order to further meet the needs of our customers for silicon carbide, Baotong has built a new 40000Kva silicon carbide smelting line, which has been put into use, and the monthly output of silicon carbide blocks has reached 6000-7000 tons. The annual output of boron carbide sand can reach 500 tons. Boron carbide refractory powder up to 400 tons. Boron carbide fine powder 90 tons nuclear industrial grade 100 tons.The company has been focusing on local brands in domestic and foreign markets, with huge development opportunities. Under the leadership of Mr. Li, the company has always pursued the brand marketing concept of advancing with The Times, quality innovation, variety innovation and service innovation, adhered to the implementation of brand strategy and sustainable development strategy, and constantly expanded domestic and foreign markets. The products produced by the company sell well in Europe, America, Japan, South Korea, South America and other more than 40 countries and regions, and have won the praise of domestic and foreign customers. ApplicationBoron carbide application:Control Nuclear FissionBoron carbide can absorb large amounts of neutrons without forming any radioactive isotopes, which makes it an ideal neutron absorber for nuclear power plants, and neutron absorbers are mainly used to control the rate of nuclear fission. Boron Carbide is mainly made as a controlled rod in a field, but sometimes it is made into the powder to increase the surface area. At Chernobyl nuclear accident in 1986, Russia eventually stopped the chain reaction in the reactor after dropping nearly 2,000 tons of boron carbide and sand.Grinding Polishing Lapping MaterialsBoron carbide has been used as a coarse abrasive material long before. Due to its high melting point, it is not easy to cast into artifacts, but it can be processed into simple shapes by melting the powder at high temperatures. So it is often used for grinding, lapping, drilling and polishing hard materials such as hard alloy, gems and so on.Ceramic CoatingBoron carbide can also be used as a ceramic coating for helicopters, which is lightweight Boron Carbide Sandblasting Nozzles with Longer Working Life Better Wear-resistanceBoron carbide, extremely hard and wear-resistant, no reaction with acid-base, high/low temperature resistance, high pressure resistance, crystal system: hexagonal, density: 2.52g/cm3, Mohs hardness: 9.36, microhardness 5400-6300kg/mm2, bending strength ≥400Mpa, melting point: 2450oC. Because it has the characteristics of wear resistance and high hardness, Boron Carbide Sandblasting Nozzle will gradually replace the known carbide/tungsten steel and silicon carbide, silicon nitride, alumina, zirconia and other materials sandblasting nozzle.Packaging & ShippingFAQQ1: Can we get the sample for reference?A1: We are glad to send samples for your inspection, but you need to pay thesample(depends on product's value) and the express fees.Q2: How long will be my goods ready for shipment ?A2: Different specification products with different quantity ordered, the time of delivery is different. As usual, it will take 15-25 work days.Q3: How can we guarantee quality?A3: Always a pre-production sample before mass production and always a final inspection beforeshipment.Q4: What is your terms of payment?A4: T/T, L/C, PayPal, and can be negotiated.Q5: How to solve the quality problems after sales?A5: (1) Take photos of the problems and send to us.(2) Take videos of the problems and send to us.(3) Send back the defective products to us if necessary.
