Global fumed silica market trend 2022-2030 What is Fumed Silica? by Newstiohardiman

Under the spread of the new crown epidemic, after Americans experienced life and death, they set off the largest "resignation wave" in history, and the number of resignations broke the highest record since statistics began in 2000. Since April this year, more than 4 million people in the United States have voluntarily resigned each month. In August, the number of resignations exceeded 4.27 million, and in November, it rose to 4.4 million. The operation of society is linked. The large number of departures in the United States has led to a large shortage of labor; and the shortage of a large number of labor has directly led to the supply chain crisis in the United States; the supply chain crisis has directly affected prices and prices in the United States. The economy has a direct effect on people's lives.
The economic downturn will affect the market demand for fumed silica.

Fumed silica is a nanometer white powder produced by the hydrolysis of silicon halide at high temperature in an oxyhydrogen flame. It is a kind of amorphous silicon dioxide product, the primary particle size is between 7~40nm, the aggregate particle size is about 200-500 nm, the specific surface area is 100~400m2/g, high purity, and SiO2 content is not less than 99.8%. The vapor phase silica aggregates with untreated surfaces contain a variety of silica hydroxyl groups. 
One is an isolated, undisturbed free hydroxyl group; The other is bonded silyl groups that are linked and form hydrogen bonds to each other. The vapor phase silica aggregates with the untreated surface are aggregates containing multiple -Oh compounds, which can easily form a uniform three-dimensional network structure (hydrogen bond) in the liquid system.  This three-dimensional network structure (hydrogen bond) with external force (shear force, electric force, etc.) will be destroyed, the medium becomes thin, the viscosity drops, and once the external force disappears, the three-dimensional structure (hydrogen bond) will restore itself, the viscosity rises, that is, this thixotropy is reversible.



 
Fumed silica is one of the most important new inorganic materials. It has a small particle size, large specific surface area, strong surface adsorption, large surface energy, high chemical purity, good dispersion performance, thermal resistance, resistance, and other aspects of specific performance. In addition, its high stability, its reinforcing effect, thickening, and thixotropy, in many fields of unique characteristics make it irreplaceable.
It is widely used in various industries as additives, catalyst carriers, petrochemical, decolorizing agent, matting agent, rubber reinforcing agent, plastic filling agents, ink thickening agents, metal soft polishing agents, insulation and adiabatic filler, advanced daily cosmetic filler, and spraying materials, medicine, environmental protection, and other fields.
 
Fumed silica mainly has two "sex”: hydrophilic and hydrophobic. People can use physical, chemical, and mechanical methods to deal with the fumed silica surface or interface, in order to change its chemical and physical properties of the fumed silica surface, such as surface energy, surface wettability, electrical, adsorption, and reaction characteristics, surface structure and functional groups, etc. Therefore, it can meet the modern new material, new technology, and the needs of the development of new technology. 



Hydrophobic fumed silica applications
Thickening of polar liquids, such as epoxy resins; Silicone elastomer reinforcement; High addition, as in molded products; Good hydrophobicity, improving anticorrosion; Improved dielectric properties, as in cable composites; Powder flow AIDS, such as powder coatings and fire extinguishing agents; Improve scratch resistance in coatings and plastics.

Chile's government has decided to create a state-owned lithium enterprise and hopes to establish a model for the company by the end of the year, Mining Minister Marcela Hernando said in an interview.  

Chile is the world's second largest lithium producer and has the largest reserves of lithium in the world. The domestic lithium industry is currently dominated by two private companies, Albemarle and SQM.  

Chile wants to participate more closely in the booming lithium market after leftist President Gabriel Boric took office in March. The accelerating electrification of the global auto industry has helped push prices of lithium, a key raw material for electric car batteries, to record highs over the past year, lapping up more players, including Mexico and Argentina, who want a piece of the market.  

According to Hernando, the government is setting up a task force to determine the best way to run state-owned lithium enterprises. She said the government hopes to establish plans by the end of the year for how the company will develop and what business model it will operate under. 

Hernando stressed that while the state would be a major shareholder in the proposed company, it was open to private investment.

Luoyang Tongrun Nano Technology (TRUNNANO) is a global chemical material supplier providing high-quality chemicals and Nanomaterials including graphite powder, 3D printing powder, the fumed silica.
