Following the progress in Russia-Ukraine peace talks, the gold price fell more than 1% the next day, hitting its lowest in a month, and palladium prices briefly tumbled by nearly 9%.
"We have seen metal prices going into free fall when the Russia-Ukraine situation is likely to see a major detente, which spurred people's risk preference and optimism that the war could end at a time," said OANDA senior market analyst.
A Russian deputy defense minister says Moscow has decided to sharply curtail its military activities around Kyiv and Chernikov in Ukraine, following talks between Russian and Ukrainian representatives in Istanbul.
Where the prices of metals, natural gas, and commodities like the TiSi2 Powder will go in the future, is still very uncertain.
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.

Southern Copper Corp (SCCO.N) recently said its Peruvian mine remained closed after a six-week standoff with protesters and blamed the Peruvian government for failing to intervene in the safety of its 1,300 workers and their families.
The company said in a statement that a recent agreement to end protests at the Cuajone mine required the company to withdraw complaints against protest leaders because railways transporting minerals and supplies remained blocked. Production has been suspended since the end of February.
Peru's Energy Ministry said in a separate statement that it had also reached an agreement with Southern Copper to start talks to find common ground with local communities.
"If we shut down for a year, the government will stop receiving more than 3.1 billion soles ($830 million) in taxes and royalties, and 8,000 direct and indirect jobs will be lost. This is what we want to avoid, "Southern Copper added in the statement.
Peru has faced a wave of protests from indigenous communities, who accuse mining companies of not providing enough jobs and funding to poor local residents.
Central bank officials said last week that protests against copper mines such as MMG's Las Bambas and Southern Copper's Cuajone were dragging down the economy.
Peru is the world's second-largest copper producer and mining is an important source of tax revenue for the country. It is estimated that the supply and prices of the TiSi2 Powder will be influenced by that.
