Now China has become a powerful country in science and technology, but do you know how powerful China's technology is? The manned space station alone is not enough, and now it has successfully broken through the key technology of nuclear fusion, even leading the world by 15 years. Does this mean that China is not far from the artificial sun? It turned out that the fully superconducting tokamak nuclear fusion experimental device developed by China at the Hefei Research Institute of the Chinese Academy of Sciences successfully achieved a record of 101 seconds of continuous operation at 120 million degrees Celsius, and broke the world record. Compared with the previous record in South Korea, China has time has been directly extended by 5 times, and it seems that we are one step closer to the practical stage of artificial sun.
The success of nuclear fusion technology will lead to the development of hollow glass microsphere.
A hollow glass microsphere is a kind of hollow microsphere with a thin wall, high strength, and smooth surface, which is a new kind of micron-level light inorganic material developed in the 1950s and 1960s. It not only has the advantages of low density, high strength, low thermal conductivity, high wave penetration, and good stability, but also has insulation, self-lubrication, sound insulation, fire resistance, corrosion resistance, radiation, and other excellent properties that other non-metallic materials do not have.
Some byproducts of fly ash were found in the early years. Under the microscope, they were pearl-like hollow beads with diameters of 20~200μm and shell thickness ranging from 5% to 30% of the diameter. Its main components are SiO2, Al2O3, CaO, MgO, Na2O, and K2O. This sphere has a small specific gravity, high surface pressure, strong wear resistance, good flame retardant, and good acid resistance, high-temperature resistance, so it has been excavated out of the new function.
In the early stage of development, artificial hollow glass beads are mainly used in aerospace, national defense, and other cutting-edge applications due to their high cost. Later, the United States and Japan took the lead in the development and mass production of hollow glass beads.
Now, hollow glass beads are widely used in aerospace, 5G communications, military marine, lightweight vehicles, energy-conservative building, oilfield cementing, rubber and plastic elastomers, and many other fields. Specifically,
In 5G communications, hollow glass beads can help improve the transmittance due to their hollow glass material with a low dielectric constant of 1.0~2.0. It can be used to make 5G base station and radome materials, 5G mobile phone frame and backplane, Internet of things equipment, etc.
In rubber, elastomer, and lightweight vehicles, hollow glass beads have a good role in reducing the specific gravity, rubber plastic, and other composite materials can reduce weight by 8%~10%. In addition, hollow glass beads can also effectively improve the processing performance of materials, increase rigidity and resilience, improve the material heat insulation, sound insulation, noise reduction, flame retardant, and a series of special functions, widely used in shoes, elastic pillows, car shell, special parts, and other products.
In the coating industry, the micron particle size of hollow glass beads and hollow microspheres effect give the paint a better heat insulation effect. Therefore, it could be used for military and aerospace equipment, oil pipeline, oil tank, communication base stations, large storage silos, etc.
As an anti-corrosion coating, the addition of hollow beads makes the product has more excellent anti-fouling, anti-corrosion, anti-ultraviolet, anti-yellowing, and anti-scratch effect, so it can be used for weatherproof sunscreen and heat insulation outdoor coatings, automotive coatings, anti-fouling coatings, anti-corrosion coatings, etc.
In the adhesive industry, the addition of hollow beads can reduce the density of the adhesive, reduce the volume cost, improve the rheological properties of the adhesive, improve the thixotropy and chemical corrosion resistance, and give the product better sound insulation, heat insulation, low thermal conductivity, and dielectric properties, more excellent anti-warping, anti-cracking properties. Hollow beads are widely used in silicone, epoxy resin, acrylic acid, polyurethane, synthetic rubber, and other adhesives.
In addition, hollow glass beads are typically used in oilfield cementing, which has long been the most widely used field. The use of oil field cementing includes low-density drilling fluid and cementing cement.
Low-density drilling fluids added with hollow glass beads are not only more chemically stable, but also have excellent fluidity and better lubrication, which can reduce friction during drilling, extend the service life of drill pipe and drill bit, and other equipment, but also greatly improve drilling speed and operational efficiency. Hollow glass beads are added in the cementing cement products of low density, high strength, easy flow features, is to address the low pressure, easy leakage well solid water mud loss one of the main ways of low return, can effectively control the water loss rate, prevent pollution, during 24h the compressive strength can reach more than 15Mpa, and it can improve cementing quality, prolong the life of the well.

According to Reuters, U.S. Treasury officials said they would discuss with G7 leaders pricing caps and tariffs on Russian oil as an alternative to the embargo, which would keep the market supplied, limit price spikes, and reduce Russian revenues.
The EU foreign ministers' meeting was held in Brussels. The meeting failed to agree on the sixth round of sanctions, including an oil embargo on Russia, because of objections from Hungary.
EU High Representative for Foreign Affairs and Security Policy said at a press conference after the meeting, that the meeting failed to reach an agreement on the final adoption of the sixth round of sanctions, the permanent representatives of member states to the EU will continue to discuss. The foreign ministers faced similar difficulties trying to reach an agreement on an oil ban. He said Hungary's position was based on economic rather than political concerns.
Hungary is highly dependent on Russia for energy, getting more than 60 percent of its oil and 85 percent of its natural gas from Russia.
A few days ago, the European Commission submitted the sixth round of proposed sanctions against Russia, including a total ban on Russian oil imports by the end of this year. Hungary immediately objected and said it wanted substantial compensation from the EU to offset its loss from giving up Russian oil.
The hollow glass microsphere price is predicted to increase in the next few days, due to geopolitical factors.
