What is spherical silica powder used for?
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 spherical silica powder,Overview of spherical silica powder,Spherical silica powder application,Spherical silica powder price,Spherical silica powder supplier.
Overview of spherical silica powder
Spherical silica powder has the advantages of smooth surface, large specific surface area, high hardness and stable chemical properties.
Why spheroidize? First of all, the surface of the sphere has good fluidity and can be mixed with the resin to form a film. The amount of resin added is small, and the fluidity is the best. The filling amount of powder can reach the highest, and the weight ratio can reach 90.5%. Therefore, spheroidization means that as the filling rate of silicon powder increases, the higher the filling rate of silicon powder, the smaller the thermal expansion coefficient, the lower the thermal conductivity, and the closer to the thermal expansion coefficient of single crystal silicon, the better the performance of the electronic components produced. , the spheroidized plastic molding compound has the smallest stress concentration and the highest strength. When the stress concentration of angular powder molding compound is 1, the stress of spherical powder is only 0.6. Therefore, the spherical powder molding compound has a high yield when packaging integrated circuit chips, and is not prone to mechanical damage during transportation, installation and use. Secondly, the friction coefficient of spherical powder is small, and the wear on the mold is less, so that the service life of the mold is long. Compared with horn powder, the service life of the mold can be doubled. Plastic composite packaging molds are expensive.
Spherical silica powder application
Spherical silica powder is mainly used as electronic packaging material. The three main materials of electronic packaging are substrate material, plastic sealing material and lead frame and solder. Due to its low cost, simple process and suitable for mass production, plastic packaging has developed rapidly since its birth, and its proportion in packaging has become larger and larger. Currently, plastic packaging accounts for more than 95% of the global integrated circuit market. Among plastic packaging materials, epoxy plastic packaging (EMC) is the mainstream of integrated circuit packaging, and more than 95% of microelectronic components are sealed with epoxy plastic.
In microelectronic packaging, integrated circuit packaging mainly requires high moisture resistance, low stress, low alpha ray, resistance to dip soldering and reflow soldering, and good sealing performance. To this end, the epoxy resin must be mixed with inorganic fillers in the resin matrix, and the inorganic fillers currently used are almost all quartz powder. With the rapid development of the microelectronics industry, large-scale and ultra-large-scale integrated circuits have higher and higher requirements for packaging materials. As an important support for EMC materials, quartz powder not only conforms to the specific range of packaging, but also proposes its high purity , requirements for low content of radioactive elements, especially the requirements for spherical shape of particles.
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 materials, reduce its dielectric constant, reduce stress, greatly improve rigidity, wear resistance, weather resistance, impact resistance, compression resistance, tensile resistance, moisture resistance, fire resistance, and make the product It has good resistance to arc insulation and UV radiation.
In addition to being used in electronic packaging, spherical quartz powder can also be widely used in the manufacture of electronic inks, optical fibers, high-grade cosmetics, high-grade precision ceramics, precision grinding of optical devices and electronic components, and as fillers for special paints and coatings.

Inflationary pressures on Canadians continue to rise. The consumer-price index rose 6.7% in March from a year earlier, the biggest increase since January 1991, according to the latest figures from Statistics Canada.
On a month-on-month basis, Canada's CPI rose 1.4 percent in March, also accelerating from February's 1.0 percent rise.
Prices in the eight major sectors covered by the statistics continued to rise. The uptrend comes against the backdrop of continued price pressures in the Canadian housing market, widespread supply chain constraints, and geopolitical conflicts, according to CBC. A variety of factors have affected energy, commodity, and agricultural markets. Meanwhile, Canada's employment picture continued to improve in March, with the unemployment rate falling to a record low and the average hourly earnings of employees rising.
Excluding gasoline, Canada's CPI rose 5.5 percent year on year in March. It is also the highest since comparable data began in 1999.
The widespread supply chain constraints and geopolitical conflicts are expected to continue to affect the prices of the spherical silica powder,Overview of spherical silica powder,Spherical silica powder application,Spherical silica powder price,Spherical silica powder supplier.
