Description:
Monocrystalline silicon is a more active non-metallic element, is
an important part of crystal materials, in the forefront of the
development of new materials. Its main use is as a semiconductor
material and the use of solar photovoltaic power generation,
heating and so on. Because solar energy has many advantages such as
clean, environmental protection and convenience, in the past 30
years, solar energy utilization technology has achieved great
development in research and development, commercial production and
market development, and has become one of the world's rapid and
stable development of emerging industries. Monocrystalline silicon
wafer is monocrystalline silicon rod cut through a series of
processes, the preparation of monocrystalline silicon methods
include CZ method (CZ method), zone melting method (FZ method) and
epitaxy method, in which the cZ method and zone melting method are
used to prepare monocrystalline silicon rod. The largest demand for
zone-fused silicon single crystals comes from power semiconductor
devices.
Features:
Silica can be divided into natural silica and synthetic silica two
categories. Natural silica is mainly ultrafine powder formed by
high grade silicon ore through mechanical grinding and other
physical methods, usually quartz powder or silicon powder.
Synthetic silica is an amorphous synthetic silicon oxide powder
material, although its structure and carbon black are different,
but the application performance is similar to carbon black, and the
appearance is white, so it is customary to call it "white carbon
black". Synthetic silica is normally white flocculent powder,
physical properties for high temperature resistance, non-flammable,
non-toxic, tasteless, with good electrical insulation, so widely
used in rubber, plastics, coatings, adhesives, sealants, thermal
insulation materials and other fields. Synthetic silica is mainly
divided into fumed silica and liquid phase silica, and liquid phase
silica can be divided into precipitated silica and gel silica.

Applications:
Industrial SiO2 is called white carbon black, which is light in
weight and is an ultra-fine powder. It is a nanomaterial with great
industrial application prospects, and its application fields are
very wide, almost involving all the industries that use silica
powder. At present, the preparation methods of silica mainly
include: gas phase method, precipitation method, hydrothermal
synthesis method, microemulsion reaction method, azeotrope
distillation method and hypergravity reaction method.
1. The manufacture of glass, quartz glass, water glass, optical
fiber, electronic industry parts, optical instruments, crafts and
refractory materials.
2. Can be used for egg powder, powdered sugar, milk powder, cocoa
powder, cocoa butter, plant powder, instant coffee, soup powder,
etc.
3. When the silica crystal is perfect, it is crystal; Silica gel
after dehydration is agate; When the silica grain is less than a
few microns, it consists of chalcedony, chert and secondary
quartzite.
