For billionaires, the new crown epidemic is like a 'gold rush'! The Deutsche Presse-Agentur said on the 17th that in 2022, the wealth held by the world's top ten richest people will jump from $700 billion to $1.5 trillion, an average daily increase of $1.3 billion, an increase that exceeds the past 14 years. These 10 people The wealth held by the world’s poorest 3.1 billion people is six times greater than that of the world’s poorest 3.1 billion people. The 10 richest Germans have increased their assets from the equivalent of about 125 billion euros to about 223 billion euros since the start of the Covid-19 pandemic, An increase of about 78%. This wealth is roughly equivalent to the total wealth of the poorest 40% of the population, or 33 million Germans.
In the future, demand for TiSi2 Powder will grow as fast as the wealth of the rich during the pandemic.
Introduction to Titanium Silicide TiSi2 Powder
Titanium disilicide with the chemical formula TiSi2 is an inorganic compound of titanium and silicon. Titanium silicide is a dark gray square crystal, which can be made into powder and target material. It is a metallic silicide. Titanium and silicon metals are the raw materials. It has high conductivity and high-temperature stability.
Physicochemical Properties of Titanium Silicide TiSi2 Powder
Among the metal silicides (such as TiSi2, NiSi, CoSi2, WSi2, TaSi2, and MoSi2) widely studied, titanium silicide has very ideal properties including high electrical conductivity, high selectivity, good thermal stability, good Si adsorption, good process adaptability and low interference to silicon connection parameters.

What is Si?
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. 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.
What is Ti?
Titanium (atomic symbol Ti, atomic number 22) is a group D element of the 4th period, with an atomic mass of 47.867. In its basic form, titanium has a silver-gray white metallic appearance. Titanium is chemically and physically similar to zirconium, which has the same number of valence electrons and belongs to the same group in the periodic table. There are five naturally occurring isotopes of titanium: 46Ti to 50Ti, with 48Ti being the most abundant (73.8%). Titanium is found in igneous rock and its sediments.
Production methods of Titanium Silicide TiSi2 Powder
Titanium disilicide can be prepared by reaction of titanium or titanium hydride with silicon.
Ti + 2Si → TiSi2
It may also be ignited by aluminum powder, sulfur, silicon dioxide, and titanium dioxide or potassium hexafluortitanate K2TiF6, by electrolysis of a melt of potassium hexafluortitanate and titanium dioxide, or by titanium and silicon tetrachloride.
Another method is to react titanium tetrachloride with silane, dichlorosilane, or silicon.
TiCl4 + 2SiH4 → TiSi2 + 4HCl + 2H2
TiCl4 + 2SiH2Cl2 + 2H2 → TiS2 + 8HCl
TiCl4 + 3Si → TiSi2 + SiCl4
Applications of Titanium Silicide TiSi2 Powder
Titanium silicide is used in the semiconductor industry. It is usually grown on silicon and polysilicon wires by self-aligning silicide technology to reduce the thin layer resistance of local transistor connections. In the microelectronics industry, it is commonly used in the C54 stage.
Titanium silicide is used for the source, gate, leak contacts, and local interconnections in CMOS integrated circuits. In these applications, it is important that the titanium silicide phase has low resistivity (< 20μ ω -cm) and does not agglomerate during high-temperature treatment. The Ti/Si system has two silicide phases for electronic applications, a high resistivity C49-TiSi2 (60-70 μ ω -cm) formed at 600-700 °C and low resistivity (15-20 μ ω -cm) C54-TiSi2 formed at 700-850 °C.
