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 spherical quartz powder will go in the future, is still very uncertain.
Quartz powder, also known as silica powder, is a hard, wear-resistant, stable chemical properties of silicate minerals, its main mineral composition is SiO2. The color of quartz powder is milky white, or colorless translucent. The hardness is 7. The density is 2.65. Slightly soluble in KOH solution. The melting point is 1650℃.
The product with the general fineness in 120 mesh below is called quartz sand, and that more than 120 mesh is known as quartz powder. Quartz powder can be divided into nanometer silicon dioxide and spherical silica powder because of its fineness and morphology.
Quartz powder is widely used in the industry, including the glass industry, machinery industry, artificial quartz stone plate, ceramics and metallurgy, construction, chemical industry and other industries used in the number of products in dozens to hundreds of mesh, purity requirements are different; In plastics, coatings, adhesives and other industries as fillers, fineness requirements in hundreds of mesh to thousands of mesh, high purity requirements; Used in the integrated circuit industry, product mesh and purity requirements.
Quartz powder can be used as filler to add plastic, rubber, coating, etc., to improve performance, improve process characteristics, reduce costs, etc.
The hardness of paint film can be improved by adding high purity quartz powder into the coating. High purity spherical quartz powder has special optical properties that conventional silicon dioxide does not have. It has strong UV absorption and red-light reflection characteristics. The spectrophotometer test shows that the absorption rate of ultraviolet light within the wavelength of 400mm is as high as 70%. It can be added to the coating to form a shielding effect, to achieve the purpose of UV aging and thermal aging, while increasing the heat insulation of the coating. The high purity quartz powder was added to the coating, which obviously weakened the radiation degree of UV light to the coating, and thus reduced the curing speed of the coating.
Quartz sand can be used to remove rust because of its high hardness.
The quartz sand is installed in the sand-blasting machine, through higher air pressure or water pressure, spewed quartz sand to the metal surface of the rust, through the quartz sand and rust surface of high-speed friction contact to achieve the effect of rust removal. Some manufacturers choose to use river sand instead of quartz sand because of its low cost. But the hardness of river sand is much lower than quartz sand, the content of silica in the two is different, quartz sand silicon content of nearly 99.9%, and the soil content of river sand is more, in the sandblasting process, river sand will be quickly broken or stand on the metal surface, cannot achieve the effect of real friction derusting, and the quartz sand for derusting. High hardness, uniform, and angular particles can be fully stable contact with the rusty surface, to achieve the effect of rust removal.
Quartz powder also has a filtering effect. Quartz powder is mainly used for water treatment to remove turbidity, soften water, and reverse osmosis pretreatment, can also be used for surface water and groundwater. It can effectively remove suspended matter, organic matter, colloid, and sediment in water.

Greece will hand over Iranian oil it intercepted from a Russian-flagged tanker to the United States at the request of the U.S. Justice Department, Greek port police said recently, AFP reported. The decision angered Tehran.
In April, Greek authorities reportedly seized a Russian oil tanker, the Pegas, which was said to be heading to the Turkish port of Marmara.
Reports say the ship was docked in Calistos Bay with a crew of several people said to be Russian. The Greek coast guard said the ship had been renamed the Lana.
The report notes that the European Union imposed sanctions on Russia after the conflict broke out in February. Greek authorities seized the tanker in accordance with European Union sanctions.
According to information at the time, the tanker was carrying 115,000 tons of Iranian oil.
Iran's Ports and Maritime Organization strongly protested Greece's decision, calling it an "international bandit." "The Islamic Republic of Iran will not give up its legitimate rights and expects the Greek government to abide by its international obligations in the area of navigation and shipping," it said in a statement on its website.
Iran's Foreign Ministry, through the International Maritime Organization, called on the Greek government to release the tanker and its crew overnight, adding that "the Americans discharged their cargo," the report said.
Athens did not immediately respond to the Iranian protest and gave no further details about the oil on board or how it was handed over to the United States, the report said.
The spherical quartz powder price is expected to increase in the next few days affected by the change in supply and demand markets.
