Silicon Metal Description
Metal silicon is a product obtained by smelting quartz and coke in
an electric furnace. The content of silicon in the main component
is about 98%, and the other impurities are iron, aluminum, calcium
and the like. The main use of metallic silicon is as an additive to
non-ferrous based alloys. The properties of metallic silicon are
similar to those of antimony, lead and tin, and have semiconducting
properties; they are insoluble in acid at room temperature and are
easily soluble in alkali.
The classification of metallic silicon is usually classified
according to the content of three main impurities of iron, aluminum
and calcium contained in the metallic silicon component. According
to the content of iron, aluminum and calcium in the metal silicon,
the metal silicon can be divided into different grades such as 553,
441, 411, 421, 3303, 3305, 2202, 2502, 1501 and 1101.
Silicon Metal Application:
A large amount of silicon is used for smelting into ferrosilicon
alloys as alloying elements in the steel industry, and is used as a
reducing agent in a variety of metal smelting.
Silicon is also a good component in aluminum alloys, and most cast
aluminum alloys contain silicon.
Microporous silicon calcium insulation material Microporous silicon
calcium insulation material is an excellent insulation material. It
has the characteristics of small heat capacity, high mechanical
strength, low thermal conductivity, non-combustion, non-toxic and
tasteless, cutting and convenient transportation.
Special silicon calcium material can be used as a catalyst carrier,
widely used in petroleum refining, automobile exhaust gas
purification and many other aspects.
