Hebei Baotong New Materials Co., Ltd. is a manufacturer with advanced silicon carbide particle sand production line, silicon carbide powder production line, silicon carbide ceramic product production line, silicon carbide powder channel reactor production line and related core intellectual property rights, which can produce different specifications of cross section sand, mesh sand, fine powder and ultrafine powder. Can meet the needs of different customers.
Boron carbide application:
Control Nuclear Fission
Boron 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 Materials
Boron 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 Coating
Boron carbide can also be used as a ceramic coating for warships and helicopters, which is lightweight and has the ability to resist armor-piercing bullets penetrating the thermal coating to form a monolithic shield.
Boron Carbide Sandblasting Nozzles with Longer Working Life Better Wear-resistance
It can be used to manufacture gun nozzles in the arms industry. Boron 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.
Q1: Can we get the sample for reference?
A1: We are glad to send samples for your inspection, but you need to pay the
sample(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 before
shipment.
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. After we confirmed the problems, will give you the answer within 7 days.
Q6: Can we make our logo on the products?
A6: Yes. We can do logo as your requirement as well as your design project. And we also accept custom
service.
If you want to know more details, please always feel free to contact us, we will reply WITHIN 12 HOURS. Thank you very much!
