Hasad Foods, the agricultural investment arm of Qatar's sovereign wealth fund, said the government would increase its grain reserves from 250,000 tons to 300,000 tons in the near future, which is enough to feed the population for six months.
With a lot of deserts, Qatar suffers from water shortages, and Qatar depends on food imports for a long time. Recently, the ongoing tension in Ukraine has caused global food supply tension and rising prices.
In addition to that, the geopolitical situation also affects the supply and prices of many commodities like the 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.

The Free Trade Agreement between India and the United Arab Emirates (UAE) has come into force on.
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 UAE is the gateway to the Middle East, North Africa, Central Asia, and sub-Saharan Africa, said Subramaniam, a senior official at India's Ministry of Commerce and Industry. The agreement will help boost bilateral trade in goods from $60 billion a year now to $100 billion a year within five years.
On 18 February 2022, India and the United Arab Emirates signed the Comprehensive Economic Partnership Agreement. With the entry into force of the agreement, 90 percent of Indian goods and 65 percent of UAE goods will enjoy tariff-free market access.
Apart from its FTA with the UAE, India is also pursuing FTAs with Australia, the UK, Canada, Israel, the European Union, and the Gulf Cooperation Council.
Influenced by international situations, the supply and prices of many ZrSi2 Powder are still very uncertain.
