摘要：
Preparation of blank and dental molded part, containing color donor compounds comprises coating an oxide powder with the color donor substance； optionally classifying the coated powder and optionally filling into a matrix in pressed form； pressing the colored powder to a molded body； sintering the pressed molded body to a blank and optionally forming dental molded part from the blank. Independent claims are included for: (1) uni- or multi- colored molded bodies, blanks or dental molded parts from colored ceramic oxide powder, where the ratio of the ceramic oxide powder and color donor oxide is 100:0.0001 to 2 parts by weight； (2) a composition based on zirconium dioxide comprising 0.0001-0.75 wt.% of praseodymium such as praseodymium oxide, iron such as ferric oxide, terbium such as terbium sesquioxide or manganese such manganese oxides； and (3) molded body comprising the composition.
