Application of gas-phase silicon dioxide in the electronics industry
Insulation coating
Gas phase silica is commonly used in the field of electronics to manufacture insulation coatings for electronic products. Its high purity and nanoscale particle size enable it to effectively prevent current leakage and ensure the safe operation of electronic devices.

Chemical Mechanical Polishing (CMP)
CMP is one of the key processes in semiconductor manufacturing. Gas phase silica is widely used as an abrasive for CMP slurries due to its high purity and low impurity content. Its nanoparticles can provide excellent polishing performance, helping to achieve high-precision planarization of semiconductor substrates.

Lithium battery field
In lithium metal batteries, gas-phase silica can be used to improve the physical and chemical properties of electrodes. Its nanoscale properties can effectively inhibit the growth of lithium dendrites, thereby improving the cycling stability and safety of lithium batteries.

Packaging material
Gas phase silica can be used in electronic packaging materials, providing excellent mechanical properties and thermal stability. Its high specific surface area and adsorption performance can enhance the moisture resistance and aging resistance of packaging materials.

Other application areas of gas-phase silica
In addition to the electronics industry, gas-phase silicon dioxide also plays an important role in the following fields:
Coatings and inks
In coatings and inks, gas-phase silica serves as a thixotropic and thickening agent, which can improve rheological properties, prevent pigment settling, enhance coating adhesion and scratch resistance.
Rubber and plastic
Gas phase silica can be used in rubber and plastics as a reinforcing agent and filler, improving the strength and toughness of materials while reducing density.
Medicine and Food
Gas phase silica is widely used in the fields of medicine and food due to its non toxicity and high purity, such as as as an anti caking agent and adsorbent.
Cosmetics
In cosmetics, gas-phase silica as a filler can improve the texture and stability of the product.

Future Development Prospects
