Qu'elle soit sous forme cristalline ou amorphe, sublimée ou colloïdale, poreuse ou gel, la silice se retrouve dans une très large gamme de produits traditionnels ou plus high tech : pneus, revêtements, pâte dentifrice, médicaments, batteries, microélectronique. Le milieu industriel classe ces différentes silices par leur mode d'élaboration dictant le type de matériau et donc le type d'application : la silice précipitée, la silice amorphe sublimée, le gel de silice, la silice colloïdale et le verre de silice : [...] - La silice amorphe sublimée donne des surfaces actives de 50 à 400 m²/g. En tant qu'additif elle améliore la résistance à la traction, la rigidité, la couleur, l'opacité ou la brillance. 3, record 1, French, - silice%20sublim%C3%A9e

Amorphous silica (diatomaceous earth) is composed of the skeletons of prehistoric plants known as diatoms. These skeletons are largely noncrystalline, although diatomaceous earth can contain varying amounts of crystalline quartz, which has led, in the opinon of the ACGIH, to conflicting results in studies of the pulmonary effects of exposure to this colorless to gray, odorless powder. 2, record 2, English, - amorphous%20silica
