FUMED SILICA

Fumed silica 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 different grades with BET surface area between 90 and 300㎡/g from our CNF COMPANY.
