Accrue Silica Ore Information

Picture
Accrue Supplied ROM 98%+ Silica Ore
Applications - 
Silica is a fairly widely used ceramic material both as a precursor to the fabrication of other ceramic products and as a material on its own.

Silicon Production - 
Most silicon is produced as a ferroalloy either ferrosilicon or silicon manganese, which is used exclusively in steel making. 

Silicon, as ferroalloy, is the most important deoxidiser in steel making.  

Semiconductor silicon is made mostly by reacting powdered crude metal with a gaseous mixture of hydrogen and hydrogen chloride in a fluidised bed. The main product SiHCl3 is fractionally distilled then reduced by hydrogen and is then deposited on a pre silicon filament, which is heated to about 1150°C. Further purification may be done by zone refining if required. Dopants are generally added subsequent to crystal growth.

Feedstock for silicon production;   

>98.5-99% SiO2, <0.1%Fe2O3 and <0.15% Al2O3.

General Silica Information and Usage

Picture
Background - 
Silica occurs commonly in nature as sandstone, silica sand or quartzite. It is the starting material for the production of silicate glasses and ceramics. Silica is one of the most abundant oxide materials in the earth's crust. It can exist in an amorphous form (vitreous silica) or in a variety of crystalline forms. Often it will occur as a non-crystalline oxidation product on the surface of silicon or silicon compounds.

Crystalline Forms of Silica - There are three crystalline forms of silica; quartz, tridymite, cristobalite and there are two variations of each of these (high and low.)

Fused Silica - A high purity grade of silica, fused silica (which is around 99.4-99.9% SiO2) is produced by carbon arc, plasma arc, gas fired continual extrusion or carbon electrode fusion. Fused is primarily used in the electronics industry (around 70% of the total market) where its good dielectric and insulating properties are exploited; though it may also be used as a refractory material or in investment casting.

Key Proporties - Silica is a group IV metal oxide, which has good abrasion resistance, electrical insulation and high thermal stability. It is insoluble in all acids with the exception of hydrogen fluoride (HF).
