  Product Description:                  


Micro silica ,also called silica fume or micro silica, is a byproduct of production silicon metal or ferrosilicon alloys. Silicon metal and alloys are produced in electric furnaces.The raw materials are quartz,coal and wood-chips.The smoke that results from furnace operation is collected and sold as silica fume, silica fume consists primarily of amorphous(non-crystalline) silicon dioxide(SiO2),its average granule diameter is 0.15~0.20um,specific surface area is 15000~20000m2/kg,and it has extremely strong surface active.

 Microsilica in application of Refractories


Silica Fume has a stable pH and a low impurity level and is perfectly adapted to the requirements of refractory castables. Its use improves the flow, mechanical properties (especially hot strength), and durability (via permeability reduction).

Silica fume use in refractory castables provides better particle packing. Silica fume use requires less water, while maintaining the same flow characteristics. Silica fume use also promotes low temperature sintering, and the formation of mullite in the matrix of castables. This allows production of castables which have a low permeability to gas, slag and metal penetration. Castables made with silica fume are stronger than non-silica fume castables, especially at high temperatures and higher density.  Silica fume use will attain lower porosity and are more volume stable.


 Oil Well Grouting


Whether used for primary (placement of grout as a hydraulic seal in the wellbore) or secondary applications (remedial operations including leak repairs, splits, closing of depleted zones), the addition of silica fume enables a well to achieve full production potential. Besides producing a blocking effect in the oil well grout that prevents gas migration, it provides these advantages:

Improved flow, for easier, more effective application

Dramatically decrease permeability, for better control of gas leakage

Increased durability and compressive strength

Lightweight


 Refactory and Ceramics


The use of silica fume in refractory castables provides better particle packing. It allows for less water to be used while maintaining the same flow characteristics. It also promotes low temperature sintering and the formation of mullite in the matrix of the castable. This produces a castable that has a low permeability to avoid gas, slag and metal penetration. Castables incorporating silica fume are stronger than non-silica fume containing castables especially at high temperatures with higher density they attain lower porosity and are more volume stable.
