 Boron carbide B4C powder properties

Boron carbide is insoluble in water and organic solvents, has strong chemical stability, is resistant to acid and alkali corrosion, and hardly reacts with all acid and alkali solutions. The thermal neutron capture cross section of boron carbide is large and the neutron absorption ability is strong, so it is called a neutron absorber and a semiconductor.

Application of boron carbide B4C powder

Due to its attractive combination of properties, it is a suitable material for many high-performance applications.

The excellent hardness of boron carbide makes it a suitable abrasive for grinding, polishing and water jet cutting of metals and ceramics. It is suitable for grinding, polishing, drilling and other processing of various carbide tools, molds, parts, components and gemstones. Boron carbide can be made into abrasive paste and polishing paste with appropriate amount of oil or water as lubricant.

Boron carbide can absorb a large number of neutrons without forming any radioactive isotopes. It is an ideal neutron absorber in nuclear power plants. Neutron absorbers mainly control the rate of nuclear fission. Boron carbide is mainly used in nuclear reactors as controllable rods, but is sometimes powdered due to increased surface area.

During the Chernobyl nuclear accident in 1986, Russia dropped nearly 2,000 tons of boron carbide and sand, which ultimately stopped a chain reaction within the reactor.

Abrasives

Because boron carbide has long been used as a rough grinding material. Due to its high melting point, it is not easy to cast into artificial products, but it can be processed into simple shapes by melting powder at high temperature. For grinding, grinding, drilling and polishing of hard materials such as carbide and gemstones.

Coating

Boron carbide can also be used as ceramic coatings for warships and helicopters. It is lightweight and has the ability to resist penetration of armor-piercing projectiles through thermocompression coatings, forming a complete defensive layer.

Nozzle

Why does properly poured concrete end up cracking

It is very easy to cause concrete cracking if the construction or maintenance are not done correctly. What are then the five main causes of cracking concrete?

1. The cement proportion problem: Some workers in construction will add more water for a more fluid concrete. However, this will result in an increase in water-cement ratio. This will cause the concrete to harden too quickly, and lead to cracking.

2. Transport and mixing issues: If mixing and transporting concrete takes too much time, the water in the concrete will evaporate quickly. concrete . This leads to a concrete that is weaker on the construction site, unable to meet construction specifications.

3. Construction speed

4. Maintenance is unreasonable. During the period of maintenance, if late watering isn't maintained, the result will be the Cracking phenomenon Later in the year, concrete will be used. Concrete is used in later stages of the Concrete Surface Watering You can water the concrete often to speed up the drying process. Concrete will shrink if it is not watered. Late cracking occurs when concrete strength is decreased.

5. Environmental factors: If the environment at the construction site is relatively dry and there is high temperature, wind, or both, then the concrete surface evaporation is accelerated. This results in cracking on the concrete's surface. Concrete constructions are most likely to crack in the winter or summer because of temperature variations.

Add a crack-preventing agent. A variety of inorganic composite materials can prevent the foam concrete from cracking by more than 80%. Add 2-3 kilograms of anti-cracking material per cubic meter.
