What is Silica Powder?

Quartz powder or silica powder is made of pure quartz (all-natural quartz or merged quartz) by crushing, selecting, cleaning, acid treatment, high temperature melting, squashing, great grinding, and also classification, in addition to iron as well as various other processes processed to satisfy the demands of using powder.

Silica is a type of silicon oxide, chemical formula is SiO2, in nature is one of the most typical quartz as well as various organisms. Silica is the main component of sand. Silica is just one of the most complicated and plentiful households of products, in the form of a selection of mineral compounds as well as synthetic items. Remarkable examples include merged quartz, vapor silica, silica, opal, and aerogel.

It is made use of in architectural products, microelectronics (as electrical insulators), and elements in the food and pharmaceutical industries.

What is Spherical Silica Powder?

Spherical quartz powder has the advantages of a smooth surface area, large certain surface, high firmness, and also steady chemical properties.

To start with, the spherical powder has great fluidity, as well as the resin is mixed right into a film uniformly. The material enhancement quantity is tiny, as well as the filling up quantity of quartz powder is high. The mass fraction can reach up to 90.5%. The higher the filling amount of quartz powder, the reduced the thermal conductivity, the smaller sized the thermal growth coefficient of the plastic securing material, and also the closer to the thermal development coefficient of monocrystal silicon, the far better the efficiency of the electronic parts created.

Second of all, the tension of round powder is just 60% of that of angular powder, and the stress focus of the plastic seal constructed from round quartz powder is the lowest and the stamina is the greatest. Ultimately, the surface of spherical powder is smooth, the rubbing coefficient is little, the wear of the mold and mildew is small, as well as the life span of the mold can be extended greater than 1 times.

What is Spherical Silica Powder Used For?

Mainly made use of as digital packaging materials. The 3 primary products of electronic packaging are substrate product, plastic sealing material and lead framework as well as solder. Because of its affordable, easy procedure, as well as ideal for automation, plastic packaging has been created swiftly because its birth, accounting for a raising share in packaging, the present plastic packaging in the world accounted for more than 95% of the incorporated circuit market. Among the plastic packaging materials, epoxy plastic packaging (EMC) is the mainstream of integrated circuit packaging, more than 95% of microelectronic elements utilize epoxy plastic sealing.

In microelectronic product packaging, the primary requirements of incorporated circuit product packaging high moisture resistance, reduced anxiety, low alpha ray, dip resistance and reflow welding, great sealing efficiency procedure. Consequently, epoxy material should be doped with not natural fillers in the material matrix, the inorganic fillers utilized today are almost quartz powder. With the rapid advancement of microelectronics market, large, really large incorporated circuit is greater as well as higher to the requirement of product packaging products, quartz powder, as a crucial support of EMC materials not just its size satisfy envelop particular scope, but likewise the needs of its, high purity, reduced material of radioactive elements, particularly for the particle form making use of the round needs are put forward.

Spherical silicon powder not only has good condition, yet additionally has high chemical pureness and also low web content of radioactive components, which can fulfill the technical requirements of premium incorporated circuits. It can significantly decrease the thermal development coefficient of plastic sealing product, lower its dielectric consistent, minimize tension, significantly improve the rigidity, wear resistance, weather resistance, effect resistance, compressive resistance, tensile resistance, wetness resistance, fire resistance, so that the items have great arc insulation resistance and uv radiation resistance.

Along with being utilized in the area of digital product packaging, spherical quartz powder can additionally be extensively utilized in the manufacture of electronic ink, fiber optics, top-quality cosmetics, top-quality accuracy porcelains, accuracy grinding of optical gadgets and also electronic elements, and also utilized as filler of special paint coverings, etc.
