The U.S. and its allies plan to impose sanctions on more Russian industries and supply chains.
The US government representatives recently visited Europe to consult with allies on strengthening and enforcing sanctions to punish Russia. They also plan to take action to disrupt their critical supply chains.
The US government claims that the sanctions imposed on Russia since the invasion began on February 24 have proved extremely effective, plunging Russia into a financial crisis. The sanctions include a freeze on the Russian central bank's foreign exchange assets, a ban on hard currency transactions by major Russian banks and wealthy individuals, and export restrictions on advanced semiconductors and other technologies. The sanctions have weakened the Russian economy and left the Kremlin with fewer resources.
The volatile international political situations will continue to affect the markets and prices of many commodities like the spherical silica powder.
What is Silica Powder?
Quartz powder or silica powder is made of pure quartz (natural quartz or fused quartz) by crushing, picking, cleaning, acid treatment, high temperature melting, crushing, fine grinding, and classification, in addition to iron and other processes processed to meet the requirements of the use of powder.
Silica is a kind of silicon oxide, chemical formula is SiO2, in nature is the most common quartz and various organisms. Silica is the main component of sand. Silica is one of the most complex and abundant families of materials, in the form of a variety of mineral compounds and synthetic products. Notable examples include fused quartz, vapor silica, silica, opal, and aerogel.
It is used in structural materials, microelectronics (as electrical insulators), and components in the food and pharmaceutical industries.
What is Spherical Silica Powder?
Spherical quartz powder has the advantages of a smooth surface, large specific surface area, high hardness, and stable chemical properties.
First of all, the spherical powder has good fluidity, and the resin is stirred into a film evenly. The resin addition amount is small, and the filling amount of quartz powder is high. The mass fraction can reach up to 90.5%. The higher the filling amount of quartz powder, the lower the thermal conductivity, the smaller the thermal expansion coefficient of the plastic sealing material, and the closer to the thermal expansion coefficient of monocrystal silicon, the better the performance of the electronic components produced.
Secondly, the stress of spherical powder is only 60% of that of angular powder, and the stress concentration of the plastic seal made of spherical quartz powder is the lowest and the strength is the highest. Finally, the surface of 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 more than 1 times.
What is Spherical Silica Powder Used For?
Mainly used as electronic packaging materials. The three main materials of electronic packaging are substrate material, plastic sealing material and lead frame and solder. Because of its low cost, simple process, and suitable for mass production, plastic packaging has been developed rapidly since its birth, accounting for an increasing share in packaging, the current plastic packaging in the world accounted for more than 95% of the integrated circuit market. Among the plastic packaging materials, epoxy plastic packaging (EMC) is the mainstream of integrated circuit packaging, more than 95% of microelectronic components use epoxy plastic sealing.
In microelectronic packaging, the main requirements of integrated circuit packaging high moisture resistance, low stress, low alpha ray, dip resistance and reflow welding, good sealing performance process. For this reason, epoxy resin must be doped with inorganic fillers in the resin matrix, the inorganic fillers used at present are almost quartz powder. With the rapid development of microelectronics industry, large-scale, very large-scale integrated circuit is higher and higher to the requirement of packaging materials, quartz powder, as an important support of EMC materials not only its size conform to encapsulate specific scope, but also the demands of its, high purity, low content of radioactive elements, especially for the particle shape using the spherical requirements are put forward.
Spherical silicon powder not only has good shape, but also has high chemical purity and low content of radioactive elements, which can meet the technical requirements of high-end integrated circuits. It can greatly reduce the thermal expansion coefficient of plastic sealing material, reduce its dielectric constant, reduce stress, greatly enhance the rigidity, wear resistance, weather resistance, impact resistance, compressive resistance, tensile resistance, moisture resistance, fire resistance, so that the products have good arc insulation resistance and uv radiation resistance.
In addition to being used in the field of electronic packaging, spherical quartz powder can also be widely used in the manufacture of electronic ink, optical fiber, high-grade cosmetics, high-grade precision ceramics, precision grinding of optical devices and electronic components, and used as filler of special paint coatings, etc.
