Fumed Silica Powder - XYSIL® Fumed Silica

Silica fume, also known as microsilica, (CAS number -64-2, EINECS number 273-761-1) is an amorphous (non-crystalline) polymorph of silicon dioxide, silica.It is an ultrafine powder collected as a by-product of the silicon and ferrosilicon alloy production and consists of spherical particles with an average particle diameter of 150 nm.The first solution that come to mind to solve the problem is to use filtered hot air to heat and dry the silica powder. But this solution includes very expensive filters that must be changed regularly. Moreover, the treated product is really powdery once dried. That's why SAIREM designed a custom microwave solution to dry the powder.silica aerogel aerogel powder processing raw materials powder Prior art date -10-22 Legal status (The legal status is an assumption and is not a legal conclusion.
