Title (EN) SILICA SLURRY FOR POLISHING-LIQUID COMPOSITION
(FR) SUSPENSION DE SILICE POUR COMPOSITION LIQUIDE DE POLISSAGE
(JA) 研磨液組成物用シリカスラリー
Abstract:
(EN) One embodiment of the present invention is a silica slurry for a polishing-liquid composition, said slurry comprising silica particles, a redispersion aid and water, the redispersion aid being an alkali thickening polymer emulsion, and the pH of said silica slurry being 8.0–12.0, inclusive, at 25°C. The average secondary particle size of the silica particles is preferably 150–580nm, inclusive. The silica slurry for a polishing-liquid composition preferably has a viscosity of no less than 20mPa·s at 25°C. When an acid or an oxidising agent is added to adjust the pH to 0.5–6.0, inclusive, the viscosity is preferably no more than 10mPa·s at 25°C.
(FR) Un mode de réalisation de la présente invention concerne une suspension de silice pour une composition liquide de polissage, ladite suspension comprenant des particules de silice, un auxiliaire de redispersion et de l'eau, l'auxiliaire de redispersion étant une émulsion de polymère épaississant alcalin, et le pH de ladite suspension de silice étant compris entre 8,0 et 12,0, inclus, à 25 °C. La taille de particule secondaire moyenne des particules de silice est de préférence comprise entre 150 et 580 nm, inclus. La suspension de silice pour composition de liquide de polissage présente de préférence une viscosité supérieure ou égale à 20 mPa·s à 25 °C. Lorsqu'un acide ou un agent oxydant est ajouté pour ajuster le pH entre 0,5 et 6,0, inclus, la viscosité n'est de préférence pas supérieure à 10 mPa·s à 25° C.
