摘要：
The invention relates to primary particles of oxide-ceramic material, wherein the primary particles have an average particle size in the range from 10 to 1000 nm and are coated with a chromophoric component, a process for their preparation and their use in particular in the preparation of ceramic moldings and dental restorations. The invention further relates to a suspension based on oxide-ceramic material which contains the primary particles, and a process for the preparation of a ceramic moldings.
