Recently, the EU proclaimed new sanctions on Russia, including coal, timber, rubber, cement, and fertilizer, as well as high-end seafood ZrSi2 Powder.
Introduction to Zirconium Silicide ZrSi2 Powder
Zirconium silicide or zirconium disilicide is an organic compound, the chemical formula ZrSi2, is one of the silicides of zirconium.
It can be made by the reaction of silicon and zirconium at 1100 °C or by the reaction of silicon and zirconium dioxide:
ZrO2 + 4Si -- ZrSi2 + 2SiO
When heated in the air, it forms a protective film of zirconium silicate.
Physicochemical Properties of Zirconium Silicide ZrSi2 Powder
ZrSi2 is insoluble in water, inorganic acid, and aqua regia, but soluble in hydrofluoric acid.
As a zirconium-silicon intermetallic compound, ZrSi2 is a kind of ceramic material with high hardness, high melting point, high conductivity, high heat conductivity, and good thermal shock resistance to high temperature.

Applications of Zirconium Silicide ZrSi2 Powder
ZrSi2 can be used as fine ceramic raw material powder to make crucibles or semiconductor film.
Silicon (atomic symbol Si, atomic number 14) is an element of unit P in group 14 of period 3, with an atomic mass of 28.085. The number of electrons in each shell of silbohr silicon is 2,8,4, and its electron configuration is [Ne] 3s2, 3p2. The radius of a silicon atom is 11 pm and the van der Waals radius is 210pm. By weight, silicon makes up 25.7 percent of the earth's crust and is the second most abundant element after oxygen. These metals rarely exist in pure crystal form and are usually made from an iron-silicon alloy called ferrosilicon. Element Silicon (or silicon dioxide), such as sand, is the main component of glass, which is one of the cheapest materials and has excellent mechanical, optical, thermal, and electrical properties. Ultra-pure silicon can be doped with boron, gallium, phosphorus, or arsenic to produce silicon, which is used in transistors, solar cells, rectifiers, and other solid-state devices widely used in the electronics industry.
Zirconium (Zr, atomic symbol Zr, atomic number 40) is a group D element of period 5 with an atomic mass of 91.224. Each zirconium layer has an electron number of 2,8,18,10,2 and an electron configuration of [Kr]4d2 5s2. The zirconium atom has a radius of 160pm and a van der Waals radius of 186pm. In its elemental form, zirconium has a silvery-white appearance similar to that of titanium. The main mineral of zirconium is zircon (zirconium silicate). Zirconium is commercially produced as a by-product of titanium and tin mining and has many applications as an opaque and refractory. It is not a free element in nature.
Zirconium plays an important role in industrial, medical, and defense applications around the world. Zircon metals are used as key components in many alloys due to their high strength and corrosion resistance. Zirconium alloys with high compressive strength are used in important naval and aerospace industries as components of submarine casings and high-speed aircraft alloys. Zircon's low neutron absorption properties make it irreplaceable in the inner components of fusion engines. In addition, zirconium silicate and zirconium dioxide are minerals with high refractive index and wear resistance, so they can be used in high-temperature furnace lining, refractory ceramics, and nanotechnology industries.

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 ZrSi2 Powder are estimated to be influenced by international political situation changes.
