Silicon Slag

Supplier From China
Apr-07-24

Silicon slag is a grayblack granular solid waste produced by partial oxidation and partial reduction of silicon materials at high temperatures Silicon slag mainly comes from silicon material processing processes in the metallurgy and semiconductor industries such as silicon wafer slicing ferrosilicon smelting and other processes The main components of silicon slag are SiO2 and a small amount of FeO Al2O3 CaO and other elements and oxides

1 Make cement
Silica slag can be used as an additive in cement clinker to replace some materials such as plaster of paris or fly ash in cement clinker Silica slag can promote the hydration reaction of cement clinker and enhance the early strength and longterm performance of cement
2 Making glass
Silica slag is an important raw material for glass manufacturing It can replace part of the raw materials such as quartz sand and sodium carbonate reduce the cost of glass production and at the same time improve the quality and weathering resistance of the glass
3 Manufacturing Ceramics
After silicon slag is mixed with materials such as alumina calcium oxide and magnesium oxide highperformance refractory ceramic materials can be prepared These materials have excellent properties such as hightemperature fire resistance high strength and wear resistance and are widely used in hightemperature furnaces chemical equipment and other fields
4 Manufacturing building materials
Silica slag can be used as a raw material for manufacturing building materials such as building bricks sound insulation panels and thermal insulation materials Building materials made of silicon slag have high strength wear resistance fire resistance and other properties and also have good heat and sound insulation properties
5 Other uses
Silicon slag can also be used to manufacture graphite electrodes iron oxide pigments electrical insulation materials and other products In addition silica slag can also be recycled such as used to make road hardeners lowcarbon cement etc

Silicon Slag 50

$240
MOQ: Not Specified
Supplier From Lanzhou, China
 
Silicon slag is a by-product of smelting metal silicon and ferrosilicon.It is a kind of scum floating on the furnace in the process of smelting silicon.It is content is from 45% to 70%,and the rest are C,S,P,Al,Fe,Ca. It is much cheaper than purity silicon metal.Instead of ferrosilicon for steelmaking, can reduce the cost.

Silicon slag 50 is Si greater than or equal to 50, Ca less than 5, S less than O0.1, P less than 0.05, C less than 5.

Silicon Metal Slag

$1.00K - $3.00K
MOQ: Not Specified
 
Silicon Slag Silicon Metal Slagis a byproduct from the manufacture of silicon metal it is a kind of mixture which contains the main content Silicon 3565 and other components such as C S P Al etc
It is a good substitute for FeSi in steel making which has advantage in lowing the cost of production and reusing resource Usually we use silicon slag to produce silicon briquette which is far and wide market in domestic and internationalour silicon metal is used by the chemical industry in the production of silicon compounds and by semiconductors Aluminum manufactures to improve the useful properties of aluminum as well as in the manufacture of silicon wafers used in photovoltaic solar cells and electronic

CHEMICAL BEHAVIOR
The basicity of the slag is normally fixed by the amount of lime and calcinated dolomite added, the silicon and aluminum levels of the hot metal and steel scrap charged as well as ferro-alloys.
