What is spherical silica powder?

Spherical silicon is also known as spherical silicon dioxide, spherical silicon powder, etc. in the industry. Spherical silica powder is a white powder with relatively high purity, excellent particles, good dielectric properties, and thermal conductivity; and has the advantages of low expansion coefficient and has strong development potential. When applying spherical silicon powder in current integrated circuits, the purity requirements are becoming more stringent. Under normal circumstances, the silicon content cannot be lower than 99.95%.

Features and performance of spherical silicon products:

Spherical silicon is produced by the flame fusion method. Spherical silicon dioxide is produced by silica at a very high-temperature flame. It has the characteristics of high purity, low radioactivity, good fluidity, and low thermal stress.

Nano spherical silicon is spherical crystalline silicon particles with high sphericity and high roundness. It has the characteristics of high purity, small particle size, uniform distribution, large specific surface, high fluidity, insulation, high surface activity, and low bulk density.


Spherical silicon is non-toxic, odorless, and has good activity. It is a new generation of optoelectronic semiconductor material, has a wide gap energy semiconductor, and is also a high-power light source material.

Spherical silicon has excellent properties such as high dielectric, high heat resistance, high humidity resistance, high filling content, low expansion, low stress, low impurities, and low friction coefficient.

The main application areas of spherical silica:

Spherical silica is widely used in aviation, aerospace, semiconductor, electronic components, and other materials. It can be added as a filling material with phenolic epoxy resin, adhesive, paint, high-grade ceramics, coatings, rubber, silica gel to reduce costs, increase weather resistance, hardness, etc. Spherical silica can be added to binders, catalysts, medicines, castings, and packaging materials. Spherical silica has a low thermal shrinkage rate. Adding to PVC, PP, PE, and other plastic products will not affect the color and feel, reduce thermal shrinkage, and prevent warpage.
