High Purity Spherical quartz powder Spherical SiO2,99.9%

Spherical quartz powder is characterized by its smooth surface and large specific area. It also has high levels of hardness, stability chemical properties, and high durability. Purity: 99.9% Shape: Spherical Size: 300nm About Spherical Quartz Powder Spherical SiO2 Spherical silicon quartzpowder exhibits excellent characteristics such as a flat surface and large specific area. First, the Spherical Powder Fluidity and the resin are stirred evenly into a thin film. The resin addition amount is low, the quartz dust high, and mass fractions up to 90.5%. A higher filling quantity of quartz powder means a lower thermal conductivity. Also, the plastic sealing material’s thermal expansion factor is smaller. This affects the efficiency of any electronic component produced. Second, the stress level of the spherical powder can be 60% less than the angular, so the strength and stress concentration of plastic sealing materials made from spherical Quartz powder are the best. Final, the surface quality of the spherical quartz powder is very smooth. The friction coefficient and wear are low, which means that the mold’s service life can be increased by up to 1 time.

Performance of Spherical quartz powder Spherical SiO2: 1. You can add high sphericity to uniform size but the viscosity is not affected. 2. The surface of spherical silica oxide is fluid, with uniform film formation when stirring with resin. There’s little resin used, and it has high fluidity. A lower thermal conductivity is better for electronic components. It will also reduce the thermal expansion coefficient. 3. Spherical silicon dioxide-filled plastic is used to encapsulate the integrated circuit chips. The yield is good, the friction coefficient is low, and mold wear is minimal. This makes the mold last a very long time. It is possible to improve the mold performance over angle powder. You can double the life expectancy.

How does Spherical siO2 manufactured? The spherical quartz powder is made out of quartz stone. After its purification and ultrafine milling, it undergoes a high-temperature field so that the phase, crystal, and shape changes instantaneously. The most common methods of preparation are high-temperature plasma melt, high-temperature melting injection, and gas combustion torch method. Spherical siO2 Spherical sio2 quartz powder is most commonly used for high-temperature silicone rubber, silicon defoaming agent and advanced printing ink. Spherical silica is a good form, with high chemical purity and low radioactive elements, it can meet all the technical requirements for high-end integrated systems. The application of this powder can significantly reduce the thermal expansion coefficient of encapsulation materials, decrease stress and increase rigidity, wear resistance and weather resistance. Products that have good insulation properties and resist to ultraviolet radiation are now the essential key components of electronic packaging materials. The main use of sphere quartz powder in electronics packaging is to make electronic ink and optical fiber. It can also be used for the production of high-end cosmetics, electronic ink and precision grinding optical components and optical devices.

Storage condition of Spherical Quartz Powder Spherical SiO2 : Spherical siO2 powder should be stored in dry, cool, and closed areas. This will prevent moisture from oxidizing and affecting dispersion performance.
