Fumed Silica Powder

Fumed silica powder Fumed silica is a nano-scale white powder produced by the high-temperature hydrolysis of silicon halide in a hydrogen-oxygen flame. It is an amorphous silica product with a primary particle size of 7~40nm. The aggregate particle size is about 200-500 nanometers, and the specific surface area is 100-400m2/g. The purity of fumed...

Fumed Silica Price

Some tips on fumed silica prices are provided in this post, along with advice on where/how to purchase fumed silica. Freight is a large part of the price Fumed silica is very light-weighted. Take containers as an example, one 20’GP loads only 1,800KG fumed silica, while it loads 25,000KG PAC(Poly-aluminium Chloride). Assume the freight...

Fumed Silica

FUMED SILICA Fumed silica (CAS number 112945-52-5), also known as pyrogenic silica because it is produced in a flame, consists of microscopic droplets of amorphous silica fused into branched, chainlike, three-dimensional secondary particles which then agglomerate into tertiary particles. Synonyms Pyrogenic silica; XYSIL; Aerosil; Cab-O-Sil; Cabosil; silicon dioxide amorphous, synthetic amorphous silica; fumed SiO2;...

Is fumed silica dangerous?

The general answer is “no”, fumed silica is not a dangerous material. Fumed silica is an non-toxic non-harmful material. It is not combustible nor explosive. In fact fumed silica has been applied in cosmetic, food and drugs for years. Due to its strong hygroscopicity(absorbing moisture), it may caused dry skin when directly contacted with...

Hydrophilic Fumed Silica

What is hydrophilic fumed silica Hydrophilic fumed silica is a nanomaterials with strong hygroscopicity(absorbing moisture). This fluffy white powder is based on high purity amorphous silica. It is can be wetted by water, and dispersed in water forming a suspension....

Fumed silica and silica fume

Fumed silica and silica fumed are two different terms for two substance. They are both silica dioxide. On some occasions people confused with them. They have different derivations, technical characteristics, and applications, then the price is different. Fumed silica Fumed silica, also known as pyrogenic silica because it is produced in a flame, consists...
