Introduction to Spherical silica powder
Spherical silica powder 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, very fine particles, good dielectric properties and thermal conductivity, and has the advantages of low expansion coefficient, and has strong development potential.
When the Spherical silica powder is used in current integrated circuits, the purity requirements become more and more stringent. Under normal circumstances, the silicon content cannot be lower than 99.95%.
Characteristics and performance of Spherical silica powder
Spherical silica powder is produced by flame fusion method. Spherical silicon dioxide is produced by silicon dioxide in a very high temperature flame. It has the characteristics of high purity, low radioactivity, good fluidity, and low thermal stress.
Spherical silica powder 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 silica powder is non-toxic, odorless, and has good activity. It is a new generation of optoelectronic semiconductor materials with wide gap energy semiconductors and is also a high-power light source material.
Spherical silica powder 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 powder
Spherical silica powder 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 products such as 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.
