The roble had hit a record low after the West imposed sweeping sanctions on Russia for its aggression in Ukraine. Russia's president recently ordered exports of Russian gas to "unfriendly" countries to be settled in robles. The speaker of Russia's upper house of parliament said Moscow was prepared and could shift supplies to markets such as Asia if Europe refused to buy Russian energy.
European countries, which pay mostly in euros, say Russia has no right to reset contracts. The G7 rejected Russia's demand and urged companies not to agree to pay in robles, saying most contracts stipulated payment in euros or dollars. Wholesale gas prices in Europe have risen further recently on concerns about potential supply disruptions.
The Kremlin spokesman said, "According to the March 31 deadline set by Russia's president, we are developing all payment methods to get a simple, understandable, and feasible system for relevant European and international buyers,"
The markets and prices of more commodities like the ZrSi2 Powder would be affected because of the volatile international political situations.
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.

Where is the best place for humans to live in outer space? So far, the moon is more habitable in outer space, and it is likely to be turned into a planet. However, whether humans can live on the moon for a long time, these questions have always been lingering in everyone's minds, always There is no way to get an answer. According to the report, a team from the University of Aeronautics and Astronautics in Beijing, after nearly 370 days of closed life, finally simulated the life experiment on the moon, and finally knew what the final truth was. Live here for a long time.
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.
