Commodity prices are on track for their biggest rally in more than a century, while fixed-income assets have seen their longest run of outflows as the war in Ukraine adds to inflationary pressures in the global economy emerging from the coronavirus lockdown, according to Bank of America.
"Commodity prices this year are on track to record their biggest gains since 1915." the bank said in its weekly briefing. They cite many factors, such as pandemics, lockdown, civil strife, wars, excessive monetary and fiscal stimulus, and supply chain disruptions, that have led to "historically" high inflation.
By the same token, it said government bonds were heading for their worst year since 1949, and "negative-yielding bonds will quietly disappear" from the market as central banks embark on a monetary tightening cycle and raise interest rates to tame soaring inflation.
The prices of many commodities like the Spherical SiO2 powder are expected to increase in the future.
About Spherical quartz powder Spherical SiO2:
Spherical quartz powder has excellent properties such as smooth surface, large specific surface area, high hardness and stable chemical properties. First of all, the spherical powder fluidity is good, and the resin is stirred into a film evenly, the resin addition amount is small, the filling amount of quartz powder is high, and the mass fraction is up to 90.5%. The higher the filling amount of quartz powder, the lower the thermal conductivity, the smaller the thermal expansion coefficient of plastic sealing material, the closer to the thermal expansion coefficient of monocrystalline silicon, the better the performance of the electronic components produced. Secondly, the stress of the spherical powder is only 60% of that of the angular powder, and the plastic sealing material made from the spherical quartz powder has the lowest stress concentration and the highest strength. Finally, the surface of the spherical powder is smooth, the friction coefficient is small, the wear of the mold is small, and the service life of the mold can be extended by more than 1 times. TRUNNANO is a trusted global Spherical silicon oxide quartz supplier. Feel free to send an inquiry about the latest price of spherical silicon oxide quartz powder at any time.
Performance of Spherical quartz powder Spherical SiO2：
1. High sphericity, uniform size, can be added to a large extent, the viscosity of the polymer system does not change significantly;
2. The surface of spherical silicon oxide has good fluidity, uniform film formation by stirring with resin, small amount of resin added, good fluidity and high powder filling amount. The smaller the thermal expansion coefficient and the lower the thermal conductivity, the closer it is to the thermal expansion coefficient of single crystal silicon, and the better the performance of the electronic components produced therefrom;
3. When the spherical silicon oxide-filled plastic encapsulates the integrated circuit chip, the yield is high, the friction coefficient of the spherical silicon oxide powder is small, and the wear of the mold is small, so that the service life of the mold is long. Compared with the angle powder, the mold can be improved. Double the service life;

How is Spherical quartz powder Spherical SiO2 produced?
Spheral quartz powder is made of natural quartz stone after purification and ultrafine grinding, through a certain high-temperature field, so that its phase state, crystal and shape change instantaneously, from solid to molten state to solid-state, from crystal to amorphous state, from irregular angular particles into regular spherical particles and obtained by a powder. At present, the preparation methods include high-temperature plasma melting, high-temperature melt injection and gas combustion flame method.
Applications of Spherical quartz powder Spherical SiO2:
Spherical quartz powder Spherical SiO2 is mainly used for high temperature vulcanized silicone rubber, silicone defoaming agent, advanced printing ink, powder coating, PVC resin, unsaturated polyester resin thickening, thixotropic agent, pharmaceutical powder, sheet material preparation, cosmetics, etc.
Spherical silica powder is not only good shape, and high chemical purity, low content of the radioactive element, can meet the high-end integrated circuits in all kinds of technical requirements, its application can greatly reduce the encapsulation material thermal expansion coefficient, lower the dielectric constant, reduce stress, greatly enhance rigidity and wear resistance, weather resistance, impact resistance, compressive strength, tensile, the wave resistance, flame resistance, make the products with good arc resistance insulation characteristics and resistance to ultraviolet radiation, etc., have become the indispensable key electronic packaging materials.
Spherical quartz powder is mainly used in the field of electronic packaging, but also widely used in the manufacturing of electronic ink, optical fiber, high-end cosmetics, advanced precision ceramics, precision grinding of optical devices and electronic components, and used as a filler for special paints and coatings.
Storage Condition of Spherical quartz powder Spherical SiO2：
The Spherical quartz powder Spherical SiO2 should be Stored in a dry and cool environment in a sealed place, not exposed to the air, to prevent oxidative agglomeration caused by moisture, affecting the dispersion performance and use effect;
Packing & Shipping of Spherical quartz powder Spherical SiO2：
It is packed in double plastic bags inside, which can be filled with argon in a vacuum; it can be vacuumed and filled with argon for protection..
Spherical quartz powder Spherical SiO2 Powder packing: vacuum packing, 100g, 500g or 1kg/bag, 25kg/barrel, or as your request.
