Document Type and Number:
Japanese Patent JP4804943
Kind Code:
B2
Abstract:
An objective of the present invention is to provide a production method of a dental ceramics material capable of easily expressing a color tone which is approximately similar to that of dentin of a tooth at a low cost, in which the material is not discolored when baking at high temperature. A dental ceramics material is produced by: mixing a pink coloring agent and a yellow coloring agent with zirconium oxide containing a stabilizer at a mixing ratio of 0.001 to 5 wt. % respectively; and baking, where the pink coloring agent is obtained by dissolving manganese oxide in aluminum oxide as a solid solution, the yellow coloring agent is obtained by dissolving vanadium oxide in zirconium oxide as a solid solution, and the zirconium oxide contains 0.1 1 to 30 wt. % aluminum oxide if necessary. The stabilizer is one or more kinds selected from a group including yttrium oxide, magnesium oxide, calcium oxide, and ceriumoxide, and the content thereof is preferably 3 to 7 wt.%.
