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 Zirconium Silicide ZrSi2 Powder are still very uncertain.
Introduction to Zirconium Silicide ZrSi2 Powder
Zirconium silicide or zirconium disilicide, chemical formula ZrSi2, is a steel gray rhombic glossy crystal, the relative density is 4.8822. Zirconium silicide is insoluble in water, inorganic acid, and aqua regia, but soluble in hydrofluoric acid.
Physicochemical Properties of Zirconium Silicide ZrSi2 Powder
ZrSi2 as a zirconium-silicon intermetallic compound 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. Given the silicon zirconium - intermetallic compound has superior physical and chemical properties, ZrSi2 is a kind of structural material or new engineering material which can be used as the high-temperature corrosive medium.

Preparing Methods of Zirconium Silicide ZrSi2 Powder
Zirconium silicide can be obtained from a mixture of zirconium powder and silicon powder at high temperatures under air isolation.
A method for preparing zirconium silicide nanomaterial comprises the following steps:
1. Add 5mmol zirconia, 5mmol silicon powder, and 50mmol lithium metal into a 20ml stainless steel autoclave and seal it. Then put the autoclave into an electric furnace capable of temperature programmed, set the heating rate of the furnace to 10℃ per minute, and heat the furnace to 600℃. The reaction is cooled naturally to room temperature and the autoclave is opened to remove the product which is black sediment.
2. The reaction products were washed with distilled water, then respectively with dilute hydrochloric acid and anhydrous ethanol washing each time, after washing the product of the filter, then 60 ℃ in the vacuum drying oven drying 4 hours get zirconium silicide nanomaterials, based on the preparation of zirconium silicide nanomaterial quality and the quality of the raw material of zirconium dioxide used, it is concluded that the yield of zirconium silicide was 85%.
Applications of Zirconium Silicide ZrSi2 Powder
ZrSi2 can be used as fine ceramic raw material powder to make crucibles or semiconductor film.
Applications of Zr Zirconium
One of the most important applications of zircon is in the production of white pigment impervious agents for surface glazes and pigments in the tile and ceramic industries. Refractory applications are also a common use of zircon in the manufacture of firebricks and shapes used in the steel and glass industries. Due to its high melting point (2200℃), zircalite is used as casting sand for molds and as "flour" for grinding, especially in warmer applications where it is important to maintain the surface quality of castings. The area of expertise known as "investment casting" is the growing use of zircon in the industry. Zirconium is also used in the production of zirconia, zirconium metals, and zirconium chemicals.
