Title
(EN) COATED PARTICLES OF CALCIUM CARBONATE HAVING A HIGH SPECIFIC SURFACE
(FR) PARTICULES ENROBEES DE CARBONATE DE CALCIUM POSSEDANT UNE SURFACE SPECIFIQUE ELEVEE
Abstract
(EN) The present invention relates to particles of an alkaline earth metal carbonate which are at least partially coated with at least one coating agent and which have a specific surface of more than 50 m2g-1 before coating. Preferably, the alkaline earth metal is calcium and the coating agent comprises a compound selected from the group consisting of organic sulfonic acids, alkylsulfates, fatty acids and the salts thereof.
(FR) L'invention concerne des particules d'un carbonate de métal terreux alcalin du moins partiellement enrobées avec au moins un agent d'enrobage et possédant une surface spécifique supérieure ou égale à 50 m2g-1 avant enrobage. De préférence, le métal terreux alcalin est du calcium et l'agent d'enrobage comprend un composé choisi dans le groupe comprenant des acides sulfoniques organiques, des alkylsulfates, des acides gras et les sels de ceux-ci.
