KONASIL , is a fluffy, white powder of amorphous structure. Because of its extremely small particle size and spherical morphology, high surface area, unique surface chemistry and high purity, this product is being used in various industrial applications. The average diameter of the spherical primary particle varies from 7 to 40nm by using different reaction conditions during flame hydrolysis. There are various KONASIL grades with BET surface area between 50 and 380m?g.

KONASIL is divided into two groups according to surface chemistry. 

• Hydrophilic silica : These silicas are produced during the normal flame hydrolysis of silane.
• Hydrophobic silica : These silicas are produced by reacting hydrophilic silica with organosilanes such as dimethyldichlorosilane etc. Hydrophobic fumed silica is used in those critical applications where resistance to water absorption is important.
