Boron carbide B4C powder is a synthetic superhard material
Commodity prices are on track for their biggest rally in more than a century, while fixed-income assets have seen their longest run of outflows as the war in Ukraine adds to inflationary pressures in the global economy emerging from the coronavirus lockdown, according to Bank of America.
"Commodity prices this year are on track to record their biggest gains since 1915." the bank said in its weekly briefing. They cite many factors, such as pandemics, lockdown, civil strife, wars, excessive monetary and fiscal stimulus, and supply chain disruptions, that have led to "historically" high inflation.
By the same token, it said government bonds were heading for their worst year since 1949, and "negative-yielding bonds will quietly disappear" from the market as central banks embark on a monetary tightening cycle and raise interest rates to tame soaring inflation.
The prices of many commodities like the Boron Carbide B4C Powder,Overview of Boron Carbide B4C Powder,Boron carbide B4C powder application,Boron carbide B4C powder price,Boron Carbide B4C Powder Supplier are expected to increase in the future.
Overview of Boron Carbide B4C Powder
Boron carbide, also known as black diamond, is an inorganic substance with the chemical formula B4C, usually a gray-black micropowder. Hard black shiny crystals. The hardness is lower than that of industrial diamond, but higher than that of silicon carbide. Less brittle than most pottery. Has a large thermal energy neutron capture cross section. Strong chemical resistance. Not attacked by hot hydrogen fluoride and nitric acid. Soluble in molten alkali, insoluble in water and acid. Relative density (d204) 2.508~2.512. Melting point 2350 ℃. Boiling point 3500 ℃. It is one of the three hardest known materials (after diamond and cubic boron nitride) and is used in tank armor, body armor and many industrial applications. It has a Mohs hardness of about 9.5.

It was discovered in the 19th century as a by-product of metal boride research and was not studied scientifically until the 1930s. Boron carbide can be obtained by reducing boron trioxide with carbon in an electric furnace.
Boron carbide can absorb a large number of neutrons without forming any radioisotopes, so it is an ideal neutron absorber in nuclear power plants, and neutron absorbers mainly control the rate of nuclear fission. Boron carbide is mainly made into controllable rods in nuclear reactors, but sometimes it is made into powder to increase the surface area.
Boron carbide B4C powder application
Because of its low density, high strength, high temperature stability and good chemical stability. It is used in wear-resistant materials, ceramic reinforced phases, especially in lightweight armor, reactor neutron absorbers, etc. In addition, compared with diamond and cubic boron nitride, boron carbide is easy to manufacture and low in cost, so it is more widely used. It can replace expensive diamond in some places and is commonly used in grinding, grinding, drilling, etc. applications.
control nuclear fission
Boron carbide can absorb a large number of neutrons without forming any radioisotopes, so it is an ideal neutron absorber in nuclear power plants, and neutron absorbers mainly control the rate of nuclear fission. Boron carbide is mainly made into controllable rods in nuclear reactors, but sometimes it is made into powder to increase the surface area.
During the Chernobyl nuclear accident in 1986, Russia finally stopped the chain reaction in the reactor after dropping nearly 2,000 tons of boron carbide and sand.
Abrasives
Since boron carbide has been used as a grit abrasive a long time ago. Due to its high melting point, it is not easy to be cast into artificial products, but it can be processed into simple shapes by melting powder at high temperature. It is used for grinding, grinding, drilling and polishing of hard materials such as cemented carbide and precious stones.
coating paint
Boron carbide can also be used as a ceramic coating for warships and helicopters.
nozzle
In the arms industry, it can be used to manufacture gun nozzles. Boron carbide, extremely hard and wear-resistant, no reaction with acid and alkali, high/low temperature resistance, high pressure resistance, density ≥2.46g/cm3; microhardness ≥3500kgf/mm2, flexural strength ≥400MPa, melting point 2450℃.
Because of the above characteristics of wear resistance and high hardness of boron carbide nozzles, boron carbide sandblasting nozzles will gradually replace known sandblasting nozzles of cemented carbide/tungsten steel and silicon carbide, silicon nitride, alumina, zirconia and other materials .
other
Boron carbide is also used in the manufacture of metal borides and in the smelting of sodium boron, boron alloys and special welding.

Southern Copper Corp (SCCO.N) recently said its Peruvian mine remained closed after a six-week standoff with protesters and blamed the Peruvian government for failing to intervene in the safety of its 1,300 workers and their families.
The company said in a statement that a recent agreement to end protests at the Cuajone mine required the company to withdraw complaints against protest leaders because railways transporting minerals and supplies remained blocked. Production has been suspended since the end of February.
Peru's Energy Ministry said in a separate statement that it had also reached an agreement with Southern Copper to start talks to find common ground with local communities.
"If we shut down for a year, the government will stop receiving more than 3.1 billion soles ($830 million) in taxes and royalties, and 8,000 direct and indirect jobs will be lost. This is what we want to avoid, "Southern Copper added in the statement.
Peru has faced a wave of protests from indigenous communities, who accuse mining companies of not providing enough jobs and funding to poor local residents.
Central bank officials said last week that protests against copper mines such as MMG's Las Bambas and Southern Copper's Cuajone were dragging down the economy.
Peru is the world's second-largest copper producer and mining is an important source of tax revenue for the country. It is estimated that the supply and prices of the Boron Carbide B4C Powder,Overview of Boron Carbide B4C Powder,Boron carbide B4C powder application,Boron carbide B4C powder price,Boron Carbide B4C Powder Supplier will be influenced by that.
