Recently, covid 19 outbreak spreads in Shanghai, China. There are more than 25,000 new asymptomatic domestic infections every day. China is implementing a dynamic zero-out policy. A leading respiratory expert said the key to COVID-19 prevention and control is to minimize transmission and fatality rate. Omicron has a low case fatality rate but is highly transmissible and can still claim many lives in large outbreaks. "Total openness is not applicable in China. For China, we should keep to the dynamic zero-out and gradually open up."
However, "dynamic zero clearance" is not the pursuit of complete "zero infection". As the Novel Coronavirus has its own uniqueness and strong concealment, there may be no way to prevent the detection of cases at present, but rapid detection and prompt treatment must be carried out, as soon as one case is found, one case will be dealt with.
The situation in Shanghai is serious. As the financial center of China, Shanghai is a very important city, and the outbreak of the epidemic in Shanghai will put a great impact on China's economy. The current task is to contain the spread of the epidemic as soon as possible, to achieve social zero so that Shanghai's life and economy quickly return to normal.
As China plays an important role in the global supply chain, the outbreak will have a significant impact on the supply and prices of many 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.
