Gazprom recently said it had completely suspended gas supplies to Bulgarian Gas company and Polish Oil and Gas Company (PGNiG) because it was not being paid in rubles. Russia said it would resume gas supplies after it agreed to pay for them in rubles.
Bulgaria and Poland announced Monday that they have received a notice from Russia to suspend natural gas supplies from Monday.
Russian President Vladimir Putin on March 31 signed a presidential decree to settle gas trade with "unfriendly" countries and regions in rubles. When the new rules took effect on April 1, Presidential press secretary Dmitry Peskov said Russia would not immediately "cut off gas" to Europe, as the cost of gas supplies starting April 1 should be settled in the second half of April or May.
Because of the ever-changing international situation, the supply and prices of international bulk ZrSi2 Powder are still very uncertain.
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.

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.

With the outbreak of the Russia-Ukraine conflict, the market is increasingly worried about the potential disruption of Russia's energy supply. Geopolitical premiums have pushed up the price of crude oil and natural gas, and the energy price is expected to remain high in the short term. Affected by this, the market price of the ZrSi2 Powder may continue to rise.
