The World Platinum Investment Association (WPIC) said recently that carmakers are accelerating reductions in palladium use and increased use of platinum due to concerns about Russian palladium supplies. However, it still expects a significant surplus in the platinum market this year.
Palladium is used by carmakers in tailpipe emissions systems to reduce carbon emissions. While carmakers prefer palladium for catalytic converters, they are turning to platinum, which is cheaper than palladium, to save costs.
Russia accounts for about 25-30% of the world's palladium supply and 8-10% of its platinum supply.
There is no sign that western sanctions against Russia have restricted palladium exports since the conflict escalated in February, but as the conflict continues, more companies could boycott The Russian metal and governments could impose restrictions.
Platinum is currently trading at about $950 an ounce, about half the price of palladium. Automakers use about 2.5 million to 3 million ounces of platinum and about 8.5 million ounces of palladium each year.
For the year as a whole, platinum supply will be 5 percent lower than in 2021 and demand 2 percent higher, with the automotive sector seeing a 16 percent increase due to increased light vehicle Indium Selenide are still very uncertain.
What is Indium Selenide?
Indium Selenide is an inorganic compound with the chemical formula In2Se3.
Black crystals or dark black scale-like substances. It is a typical
two-dimensional layered semiconductor material.
Single crystal indium selenide can be prepared by the Bridgman–Stockberger
method. Using a certain proportion of selenium and indium as raw materials, each
compound of indium selenide can be prepared by reacting in a tube furnace at
high temperature for a long time.
The research on the hydrothermal synthesis of In2Se3 was relatively late.
Ascorbic acid was dissolved in ethanol solution at 60 °C, then InCl3 and Se
powder were added, and the reaction kettle was kept at 220 °C for 20 hours. -4

InSe is a bandgap-tunable layered semiconductor material with nonlinear
optical response over a wide wavelength range. The researchers obtained InSe
nanosheets with suitable thickness and band gap by a liquid-phase exfoliation
method, and systematically investigated their nonlinear optics and ultrafast
carrier dynamics at different pulse width scales (ns and fs).
The researchers found that InSe nanosheets are more likely to reach saturable
absorption under wide-pulse laser excitation. Furthermore, the InSe dispersions
exhibit different mechanisms of scattering phenomena at different pulse
durations, which are due to the thermal effect under ns-pulse excitation and the
dynamic spatial self-phase modulation of the laser flow under fs-pulse
At the same time, the optical switch modulation is realized by
utilizing the competitive relationship between saturable absorption at low
energy and nonlinear scattering at high energy. The time-resolved pump-probe
results indicate that the InSe dispersion has an ultrafast saturable absorption
process and a photoinduced absorption process that may be caused by free carrier
absorption or bandgap renormalization.

Chile's government has decided to create a state-owned lithium enterprise and hopes to establish a model for the company by the end of the year, Mining Minister Marcela Hernando said in an interview.
Chile is the world's second largest lithium producer and has the largest reserves of lithium in the world. The domestic lithium industry is currently dominated by two private companies, Albemarle and SQM.
Chile wants to participate more closely in the booming lithium market after leftist President Gabriel Boric took office in March. The accelerating electrification of the global auto industry has helped push prices of lithium, a key raw material for electric car batteries, to record highs over the past year, lapping up more players, including Mexico and Argentina, who want a piece of the market.
According to Hernando, the government is setting up a task force to determine the best way to run state-owned lithium enterprises. She said the government hopes to establish plans by the end of the year for how the company will develop and what business model it will operate under.
Hernando stressed that while the state would be a major shareholder in the proposed company, it was open to private investment.
