What is Silica Powder?

Quartz powder or silica powder is made of pure quartz (natural quartz or fused quartz) by squashing, choosing, cleansing, acid treatment, heat melting, squashing, fine grinding, and category, in addition to iron and other procedures refined to meet the needs of using powder.

Silica is a sort of silicon oxide, chemical formula is SiO2, in nature is the most common quartz as well as various microorganisms. Silica is the main component of sand. Silica is one of one of the most intricate and also plentiful households of products, in the type of a variety of mineral substances and artificial items. Significant instances consist of fused quartz, vapor silica, silica, opal, and also aerogel.

It is used in structural products, microelectronics (as electrical insulators), and also elements in the food and also pharmaceutical markets.

What is Spherical Silica Powder?

Spherical quartz powder has the advantages of a smooth surface area, large certain surface, high solidity, as well as stable chemical residential or commercial properties.

First off, the spherical powder has great fluidness, as well as the resin is mixed right into a movie evenly. The material addition quantity is little, and the filling amount of quartz powder is high. The mass portion can rise to 90.5%. The greater the filling up quantity of quartz powder, the reduced the thermal conductivity, the smaller the thermal development coefficient of the plastic securing material, and also the closer to the thermal development coefficient of monocrystal silicon, the much better the efficiency of the electronic components produced.

Second of all, the stress of spherical powder is only 60% of that of angular powder, and the stress and anxiety concentration of the plastic seal constructed from spherical quartz powder is the lowest as well as the stamina is the highest. Lastly, the surface area of spherical powder is smooth, the friction coefficient is small, the wear of the mold is little, and the service life of the mold can be extended more than 1 times.

What is Spherical Silica Powder Used For?

Mainly utilized as digital product packaging materials. The three primary products of digital product packaging are substrate product, plastic securing product as well as lead frame and solder. Because of its low cost, simple procedure, as well as suitable for automation, plastic product packaging has been developed swiftly since its birth, accounting for an enhancing share in packaging, the existing plastic packaging worldwide accounted for greater than 95% of the incorporated circuit market. Among the plastic packaging products, epoxy plastic product packaging (EMC) is the mainstream of incorporated circuit product packaging, greater than 95% of microelectronic components make use of epoxy plastic sealing.

In microelectronic packaging, the primary requirements of incorporated circuit packaging high moisture resistance, reduced anxiety, reduced alpha ray, dip resistance and also reflow welding, excellent sealing efficiency procedure. Because of this, epoxy material have to be doped with not natural fillers in the resin matrix, the not natural fillers made use of at present are nearly quartz powder. With the quick development of microelectronics sector, large-scale, extremely massive incorporated circuit is higher and greater to the need of packaging products, quartz powder, as a vital assistance of EMC materials not only its size adapt encapsulate specific extent, yet additionally the demands of its, high pureness, low material of radioactive components, particularly for the bit shape using the spherical demands are put forward.

Round silicon powder not just has good condition, however likewise has high chemical pureness and also reduced content of radioactive aspects, which can meet the technological needs of premium integrated circuits. It can significantly reduce the thermal expansion coefficient of plastic sealing material, decrease its dielectric continuous, lower anxiety, considerably improve the strength, use resistance, weather condition resistance, effect resistance, compressive resistance, tensile resistance, dampness resistance, fire resistance, so that the items have great arc insulation resistance and uv radiation resistance.

Along with being made use of in the area of electronic packaging, round quartz powder can additionally be commonly used in the manufacture of digital ink, optical fiber, high-grade cosmetics, state-of-the-art accuracy ceramics, accuracy grinding of optical devices as well as electronic components, and also utilized as filler of special paint finishings, and so on.
