For billionaires, the new crown epidemic is like a 'gold rush'! The Deutsche Presse-Agentur said on the 17th that in 2022, the wealth held by the world's top ten richest people will jump from $700 billion to $1.5 trillion, an average daily increase of $1.3 billion, an increase that exceeds the past 14 years. These 10 people The wealth held by the world’s poorest 3.1 billion people is six times greater than that of the world’s poorest 3.1 billion people. The 10 richest Germans have increased their assets from the equivalent of about 125 billion euros to about 223 billion euros since the start of the Covid-19 pandemic, An increase of about 78%. This wealth is roughly equivalent to the total wealth of the poorest 40% of the population, or 33 million Germans.
In the future, demand for boron carbide will grow as fast as the wealth of the rich during the pandemic.

Boron carbide is one of the most stable substances to acid, and it is stable in all concentrated or dilutes acid or alkali aqueous solutions. Boron carbide is basically stable below 800°C in an air environment. The boron oxide formed by its oxidation at a higher temperature is lost in the gas phase, leading to its instability and oxidation to form carbon dioxide and boron trioxide.
How is Boron Carbide B4C Boride Powder produced?
Boron Carbide B4C Boride Powder is produced by reducing boron oxide with carbon at high temperatures in an electric furnace. After grinding, the black powder is solidified by pressing at temperatures exceeding 2,000°C (3,630°F). Its melting point is approximately 2,350°C (4,260°F).

Other size of Boron Carbide B4C powder: 500nm
Boron Carbide B4C Powder Uses:
Fine and advanced abrasive materials
Because of the high grinding efficiency of boron carbide, it is mainly used as a grinding medium in the grinding process of materials, such as: grinding, grinding, drilling and polishing of hard materials such as gems, ceramics, knives, bearings, and cemented carbides.
Industrial ceramic materials
Products made of boron carbide powder: sandblasting nozzles, sealing rings, nozzles, bearings, plungers of mud pumps, pestles and rocket launchers, ceramic coatings for warships, helicopters, etc., as a new type of material. It has the characteristics of high melting point, high hardness, high elastic modulus, strong wear resistance, and good self-lubricating properties and is widely used in sandblasting machinery, electronics, information, aerospace, automobile and other industries.
Shielding and control materials for the nuclear industry
Boron carbide material has a large thermal neutron capture section, excellent neutron absorption and radiation resistance, and is internationally recognized and recommended as a nuclear reactor control material and shielding material.
Due to its high strength and small specific gravity, it is especially suitable for use in lightweight bulletproof armor, such as the protection of aircraft, vehicles, ships and human bodies.
Improve the life of mechanical parts
Combine boron carbide powder with metal to produce metal-based alloy powder. After special surface treatment of this material, the original mechanical parts are more resistant to wear and corrosion resistance to acid and alkali.
Special absorber provides energy
Boron carbide, also known as "black gold", is used as a power source in powder form as a solid fuel for the rocket.
Chemical industry additives
Due to its stable chemical properties, boron carbide does not react with acid and alkali solutions and has a high chemical potential, so it is widely used in the production of other boron-containing materials, such as zirconium boride and titanium boride.
Because of its anti-oxidation and high-temperature resistance, boron carbide is used as a high-grade shaped and unshaped refractory material and is widely used in various fields of metallurgy, such as steel stoves and kiln furniture.
Storage Condition of Boron Carbide B4C powder:
Damp reunion will affect B4C powder dispersion performance and using effects, therefore, boron carbide B4C powder should be sealed in vacuum packing and stored in cool and dry room, the boron carbide B4C powder can not be exposure to air.

Boron Carbide Health & Safety Information
Goldman Sachs said its forecast for the price of Brent crude in 2023 would be cut from $125 to $10 a barrel if Iranian crude returned to the market.
From January to June in 2022, primary aluminum, copper, lead, tin and nickel were in short supply, while zinc was in excess supply, according to the World Bureau of Metal Statistics.
Global aluminium giant Hydro will close an aluminum smelter in Slovakia next month because of soaring electricity prices in Europe, adding to pressure on European industries, including the metals industry. Zinc prices were also affected, hitting a two-month high on Tuesday.
Hydro said the shutdown was a response to unfavorable conditions, including "no sign of improvement in high electricity prices in the short term". The smelter is operating at 60 per cent of its annual capacity of 175000 tonnes and will suffer huge losses if it continues to operate for the rest of 2022.
Industries from fertiliser to aluminium have been paralysed by soaring energy costs as European natural gas supplies are tight, and the worst energy crisis in decades is expected to continue into next year, with benchmark electricity prices surging to record highs on Tuesday.
