| description | Kaolin compositions comprising coarse kaolin particles are disclosed herein. The kaolin compositions can include kaolin particles having a GE brightness of at least 78 and a particle size distribution wherein at least 50% by weight of the kaolin particles have an equivalent size diameter (e.s.d.) of 30 μm or greater. In some embodiments, the kaolin compositions can include kaolin particles having a bimodal particle distribution. In other embodiments, the kaolin compositions can include kaolin particles having a low crystalline silica content, such as a crystalline silica content of 0.1% by weight or less and a particle size distribution wherein at least 50% by weight of the kaolin particles have an equivalent size diameter (e.s.d.) of 15 μm or greater. In some embodiments, the kaolin particles can be free of crystalline silica. Methods of making and using the kaolin compositions are also disclosed herein.
La présente invention concerne des compositions de kaolin comprenant des particules de kaolin grossières. Les compositions de kaolin peuvent comprendre des particules de kaolin ayant une luminosité GE d'au moins 78 et une distribution des tailles de particule dans lesquelles au moins 50 % en poids des particules de kaolin présentent un diamètre de taille équivalent (e.s.d.) de 30 µm ou plus. Dans certains modes de réalisation, les compositions de kaolin peuvent comprendre des particules de kaolin ayant une distribution bimodale de particules. Dans d'autres modes de réalisation, les compositions de kaolin peuvent comprendre des particules de kaolin ayant une faible teneur en silice cristalline, telle qu'une teneur en silice cristalline de 0,1 % en poids ou moins et une distribution des tailles de particule dans laquelle au moins 50 % en poids des particules de kaolin présentent un diamètre de taille équivalent (e.s.d.) de 15 µm ou plus. Dans certains modes de réalisation, les particules de kaolin ne contiennent pas de silice cristalline. La présente invention concerne également des procédés de fabrication et d'utilisation des compositions de kaolin. |
