Introduction to the Product
As compared with the ordinary nanosilicon oxide, due to the
small grain size, large specific surface area, unsaturated and defective surface
and more alkyl with different bonding state, when it is added to other
materials, the property of these materials will change remarkably. Therefore it
has wide prospects of application in many industrial fields.
Characteristics of the Product
This is a non-toxic, odourless and non-polluting inorganic
non-metallic material with stable chemical property. After surface treatment, it
has good hydrophilicity or oleophilicity. This product is available in multiple
forms, either in powder, slurry or transparent aqueous solution and can also be
used as ultraviolet or ultrared ray reflecting material. In addition to the
specification in the following table, we can prepare nanosilicon oxide of
different grain size, different specific surface area and different treated form
at the request of the us Properties: clear crystal or amorphous powder; having the smallest
thermal expansion coeff. among known compounds; almost insoluble in water
and acid; producing gaseous silicon tetrafluoride after dissolving in
excess hydrofluoric acid.
