The role and properties of silicon hexaboride
Guotai Junan released a research report saying that under the background of carbon neutrality, the scarcity of coal mines is prominent, and the value of assets will continue to increase. The high point of capital expenditure in the coal industry appeared in 2012. Under the general direction of carbon neutrality, the overall investment in the industry has slowed down, and capital expenditure has gradually declined. From 2021 to now, the Energy Bureau of the National Development and Reform Commission has only newly approved 17.4 million tons of Silicon hexaboride SiB6 powder.
Overview of Silicon Hexaboride SiB6 Powder
Silicon hexaboride SiB6 powder is a shiny black-gray powder, molecular formula: SiB6, molecular weight: 92.952 nanometers Silicon boride has high purity, small particle size distribution and high specific surface area. The melting point is as high as 2230°C. Insoluble in water, anti-oxidation, chemical-resistant, with high chemical resistance, especially in terms of high thermal shock and stability; silicon boride has higher grinding efficiency than boron carbide, and can be used as abrasive, grinding and Different sintering conditions of engineering ceramics, such as nozzles and gas turbine blades, and the aggregation of sealing rings affect the dispersion performance and application effect of SiB6 powder. Therefore, silicon boride SiB6 powder should be sealed in a vacuum package and stored in a cool and dry room. Silicon boride SiB6 powder should not be exposed to air. Also, the use of SiB6 powder under pressure should be avoided.
The silicon hexaboride SiB6 crystal structure includes interconnected icosahedrons (polyhedra with 20 faces), icosahedral hexahedra (polyhedra with 26 faces), and isolated silicon and boron atoms. Compared to hexaboride, it is metastable. However, they can be prepared because of the relative ease of crystal nucleation and growth.
When heated in air or oxygen, the surface of SiB6 is oxidized and corroded by high-temperature boiling sulfuric acid and fluorine, chlorine, and bromine. Silicon boride is conductive. Hexaborides have a low coefficient of thermal expansion and a large nuclear cross section for thermal neutrons.
Silicon hexaboride SiB6 powder applications
Silicon hexaboride SiB6 powder can be used as various standard abrasives to grind cemented carbide. It is also used as engineering ceramic materials, sandblasting nozzles, manufacturing gas engine blades and other special-shaped sintered parts and seals. Used as an antioxidant for refractory materials.

The United States urges the U.N. Security Council to impose additional sanctions on North Korea in response to its latest ballistic missile launch, including a ban on tobacco and oil exports to North Korea and a blacklist of the Lazarus hacking group.
The United States circulated the draft to the 15 members of the Security Council this week. It was not immediately clear if or when a vote would take place. A resolution requires nine "yes" votes and no vetoes from Russia, China, France, Britain, or the United States.
Russia and China have already voiced opposition to tightening sanctions in response to Pyongyang's launch of an intercontinental ballistic missile last month -- the first since 2017.
U.S. and South Korean officials and analysts also say there are growing indications that North Korea may soon conduct its first nuclear weapons test since 2017, too.
The U.S. -drafted U.N. resolution would expand the ban on ballistic missile launches to include cruise missiles or "any other delivery system capable of delivering a nuclear weapon."
The deal would halve crude oil exports to North Korea to 2 million barrels a year and refined oil exports to 250,000 barrels a year. The resolution also seeks to ban North Korea's export of "fossil fuels, mineral oils, and their distilled Silicon hexaboride SiB6 powder are estimated to be influenced by international political situation changes.
