Russian president demanded that exports of Russian gas to "unfriendly" countries be settled in rubles. The demand has raised concerns in Germany about possible supply disruptions and the impact on industry and households if utilities do not pay in robles. Europe gets about 40% of its gas from Russia. Last year, Europe imported about 155 billion cubic meters. Germany, Europe's largest economy, depends heavily on Russian gas.
The chief executive of Germany's E.ON said the German economy would face "significant damage, which should be avoided if possible" without Russian supplies. He also said it would take Germany three years to wean itself off Russian gas.
In the event of a supply disruption, Germany's gas network regulator would prioritize home heating over industrial use, so energy-hungry manufacturers such as steelmakers would be the first to suffer, he said.
The volatile international situations will continue to affect the markets and prices of many commodities like the spherical quartz powder.
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.

Due to the limited total amount of traditional energy, people have a huge demand for cleaner and greener new energy alternatives. Now, the emergence of graphene is unlocking the possibility of its application in the energy field, which can create a greener, more efficient, and sustainable future. Here Francesco Bonaccorso, Deputy Director of Innovation at the Graphene Flagship Program, explains how his researchers have developed a series of initiatives to bring graphene from the lab to the commercial market. Graphene has become a research hotspot for new materials in the 21st century. Graphene has been adopted by many industries, the most notable of which are healthcare and key material applications.
The development of graphene has brought huge fluctuations in the demand for spherical quartz powder, and the demand for spherical quartz powder will continue to grow in the future. You can contact us for the latest news on spherical quartz powder.
